+# Title : generateDocumentationAndDeploy.sh
+# Date created : 2016/02/22
+# Notes :
+__AUTHOR__="Jeroen de Bruijn"
+# Preconditions:
+# - Packages doxygen doxygen-doc doxygen-latex doxygen-gui graphviz
+# must be installed.
+# - Doxygen configuration file must have the destination directory empty and
+# source code directory with a $(TRAVIS_BUILD_DIR) prefix.
+# - An gh-pages branch should already exist. See below for mor info on hoe to
+# create a gh-pages branch.
+#
+# Required global variables:
+# - TRAVIS_BUILD_NUMBER : The number of the current build.
+# - TRAVIS_COMMIT : The commit that the current build is testing.
+# - DOXYFILE : The Doxygen configuration file.
+# - TRAVIS_REPO_SLUG : The username / reponame for the repository.
+# - GH_REPO_TOKEN : Secure token to the github repository.
+#
+# For information on how to encrypt variables for Travis CI please go to
+# https://docs.travis-ci.com/user/environment-variables/#Encrypted-Variables
+# or https://gist.github.com/vidavidorra/7ed6166a46c537d3cbd2
+# For information on how to create a clean gh-pages branch from the master
+# branch, please go to https://gist.github.com/vidavidorra/846a2fc7dd51f4fe56a0
+#
+# This script will generate Doxygen documentation and push the documentation to
+# the gh-pages branch of a repository specified by GH_REPO_REF.
+# Before this script is used there should already be a gh-pages branch in the
+# repository.

+# A few notes on contributions
+
+If you want to add code, please make sure it passes the clang-format style (I am using LLVM 4.0):
+
+```bash
+git ls-files -- '.cpp' '.hpp' | xargs clang-format -i -style=file
+```
+
+It is also a good idea to check this with `clang-tidy`; automatic fixes can be made using `-DCLANG_TIDY_FIX-ON` (resets to `OFF` when rerunning CMake).

+## Version 1.3: Refactor
+
+This version focused on refactoring several key systems to ensure correct behavior in the interaction of different settings. Most caveats about
+features only working on the main App have been addressed, and extra arguments have been reworked. Inheritance
+of defaults makes configuring CLI11 much easier without having to subclass. Policies add new ways to handle multiple arguments to match your
+favorite CLI programs. Error messages and help messages are better and more flexible. Several bugs and odd behaviors in the parser have been fixed.
+
+* Added a version macro, `CLI11_VERSION`, along with `*_MAJOR`, `*_MINOR`, and `*_PATCH`, for programmatic access to the version.
+* Reworked the way defaults are set and inherited; explicit control given to user with `->option_defaults()` [#48](https://github.com/CLIUtils/CLI11/pull/48)
+* Hidden options now are based on an empty group name, instead of special "hidden" keyword [#48](https://github.com/CLIUtils/CLI11/pull/48)
+* `parse` no longer returns (so `CLI11_PARSE` is always usable) [#37](https://github.com/CLIUtils/CLI11/pull/37)
+* Added `remaining()` and `remaining_size()` [#37](https://github.com/CLIUtils/CLI11/pull/37)
+* `allow_extras` and `prefix_command` are now valid on subcommands [#37](https://github.com/CLIUtils/CLI11/pull/37)
+* Added `take_last` to only take last value passed [#40](https://github.com/CLIUtils/CLI11/pull/40)
+* Added `multi_option_policy` and shortcuts to provide more control than just a take last policy [#59](https://github.com/CLIUtils/CLI11/pull/59)
+* More detailed error messages in a few cases [#41](https://github.com/CLIUtils/CLI11/pull/41)
+* Footers can be added to help [#42](https://github.com/CLIUtils/CLI11/pull/42)
+* Help flags are easier to customize [#43](https://github.com/CLIUtils/CLI11/pull/43)
+* Subcommand now support groups [#46](https://github.com/CLIUtils/CLI11/pull/46)
+* `CLI::RuntimeError` added, for easy exit with error codes [#45](https://github.com/CLIUtils/CLI11/pull/45)
+* The clang-format script is now no longer "hidden" [#48](https://github.com/CLIUtils/CLI11/pull/48)
+* The order is now preserved for subcommands (list and callbacks) [#49](https://github.com/CLIUtils/CLI11/pull/49)
+* Tests now run individually, utilizing CMake 3.10 additions if possible [#50](https://github.com/CLIUtils/CLI11/pull/50)
+* Failure messages are now customizable, with a shorter default [#52](https://github.com/CLIUtils/CLI11/pull/52)
+* Some improvements to error codes [#53](https://github.com/CLIUtils/CLI11/pull/53)
+* `require_subcommand` now offers a two-argument form and negative values on the one-argument form are more useful [#51](https://github.com/CLIUtils/CLI11/pull/51)
+* Subcommands no longer match after the max required number is obtained [#51](https://github.com/CLIUtils/CLI11/pull/51)
+* Unlimited options no longer prioritize over remaining/unlimited positionals [#51](https://github.com/CLIUtils/CLI11/pull/51)
+* Added `->transform` which modifies the string parsed [#54](https://github.com/CLIUtils/CLI11/pull/54)
+* Changed of API in validators to `void(std::string &)` (const for users), throwing providing nicer errors [#54](https://github.com/CLIUtils/CLI11/pull/54)
+* Added `CLI::ArgumentMismatch` [#56](https://github.com/CLIUtils/CLI11/pull/56) and fixed missing failure if one arg expected [#55](https://github.com/CLIUtils/CLI11/issues/55)
+* Support for minimum unlimited expected arguments [#56](https://github.com/CLIUtils/CLI11/pull/56)
+* Single internal arg parse function [#56](https://github.com/CLIUtils/CLI11/pull/56)
+* Allow options to be disabled from INI file, rename `add_config` to `set_config` [#60](https://github.com/CLIUtils/CLI11/pull/60)
+
+> ### Converting from CLI11 1.2:
+>
+> * `app.parse` no longer returns a vector. Instead, use `app.remaining(true)`.
+> * `"hidden"` is no longer a special group name, instead use `""`
+> * Validators API has changed to return an error string; use `.empty()` to get the old bool back
+> * Use `.set_help_flag` instead of accessing the help pointer directly (discouraged, but not removed yet)
+> * `add_config` has been renamed to `set_config`
+> * Errors thrown in some cases are slightly more specific
+
+## Version 1.2: Stability
+
+This release focuses on making CLI11 behave properly in corner cases, and with config files on the command line. This includes fixes for a variety of reported issues. A few features were added to make life easier, as well; such as a new flag callback and a macro for the parse command.
+
+* Added functional form of flag [#33](https://github.com/CLIUtils/CLI11/pull/33), automatic on C++14
+* Fixed Config file search if passed on command line [#30](https://github.com/CLIUtils/CLI11/issues/30)
+* Added `CLI11_PARSE(app, argc, argv)` macro for simple parse commands (does not support returning arg)
+* The name string can now contain spaces around commas [#29](https://github.com/CLIUtils/CLI11/pull/29)
+* `set_default_str` now only sets string, and `set_default_val` will evaluate the default string given [#26](https://github.com/CLIUtils/CLI11/issues/26)
+* Required positionals now take priority over subcommands [#23](https://github.com/CLIUtils/CLI11/issues/23)
+* Extra requirements enforced by Travis
+
+## Version 1.1: Feedback
+
+This release incorporates feedback from the release announcement. The examples are slowly being expanded, some corner cases improved, and some new functionality for tricky parsing situations.
+
+* Added simple support for enumerations, allow non-printable objects [#12](https://github.com/CLIUtils/CLI11/issues/12)
+* Added `app.parse_order()` with original parse order ([#13](https://github.com/CLIUtils/CLI11/issues/13), [#16](https://github.com/CLIUtils/CLI11/pull/16))
+* Added `prefix_command()`, which is like `allow_extras` but instantly stops and returns. ([#8](https://github.com/CLIUtils/CLI11/issues/8), [#17](https://github.com/CLIUtils/CLI11/pull/17))
+* Removed Windows warning ([#10](https://github.com/CLIUtils/CLI11/issues/10), [#20](https://github.com/CLIUtils/CLI11/pull/20))
+* Some improvements to CMake, detect Python and no dependencies on Python 2 (like Python 3) ([#18](https://github.com/CLIUtils/CLI11/issues/18), [#21](https://github.com/CLIUtils/CLI11/pull/21))
+
+## Version 1.0: Official release
+
+This is the first stable release for CLI11. Future releases will try to remain backward compatible and will follow semantic versioning if possible. There were a few small changes since version 0.9:
+
+* Cleanup using `clang-tidy` and `clang-format`
+* Small improvements to Timers, easier to subclass Error
+* Move to 3-Clause BSD license
+
+## Version 0.9: Polish
+
+This release focused on cleaning up the most exotic compiler warnings, fixing a few oddities of the config parser, and added a more natural method to check subcommands.
+
+* Better CMake named target (CLI11)
+* More warnings added, fixed
+* Ini output now includes `=false` when `default_also` is true
+* Ini no longer lists the help pointer
+* Added test for inclusion in multiple files and linking, fixed issues (rarely needed for CLI, but nice for tools)
+* Support for complex numbers
+* Subcommands now test true/false directly or with `->parsed()`, cleaner parse
+
+## Version 0.8: CLIUtils
+
+This release moved the repository to the CLIUtils master organization.
+
+* Moved to CLIUtils on GitHub
+* Fixed docs build and a few links
+
+## Version 0.7: Code coverage 100%
+
+Lots of small bugs fixed when adding code coverage, better in edge cases. Much more powerful ini support.
+
+* Allow comments in ini files (lines starting with `;`)
+* Ini files support flags, vectors, subcommands
+* Added CodeCov code coverage reports
+* Lots of small bugfixes related to adding tests to increase coverage to 100%
+* Error handling now uses scoped enum in errors
+* Reparsing rules changed a little to accommodate Ini files. Callbacks are now called when parsing INI, and reset any time results are added.
+* Adding extra utilities in full version only, `Timer` (not needed for parsing, but useful for general CLI applications).
+* Better support for custom `add_options` like functions.
+
+## Version 0.6: Cleanup
+
+Lots of cleanup and docs additions made it into this release. Parsing is simpler and more robust; fall through option added and works as expected; much more consistent variable names internally.
+
+* Simplified parsing to use `vector<string>` only
+* Fixed fallthrough, made it optional as well (default: off): `.fallthrough()`.
+* Added string versions of `->requires()` and `->excludes()` for consistency.
+* Renamed protected members for internal consistency, grouped docs.
+* Added the ability to add a number to `.require_subcommand()`.
+
+## Version 0.5: Windows support
+
+* Allow `Hidden` options.
+* Throw `OptionAlreadyAdded` errors for matching subcommands or options, with ignore-case included, tests
+* `->ignore_case()` added to subcommands, options, and `add_set_ignore_case`. Subcommands inherit setting from parent App on creation.
+* Subcommands now can be "chained", that is, left over arguments can now include subcommands that then get parsed. Subcommands are now a list (`get_subcommands`). Added `got_subcommand(App_or_name)` to check for subcommands.
+* Added `.allow_extras()` to disable error on failure. Parse returns a vector of leftover options. Renamed error to `ExtrasError`, and now triggers on extra options too.
+* Added `require_subcommand` to `App`, to simplify forcing subcommands. Do **not** do `add_subcommand()->require_subcommand`, since that is the subcommand, not the master `App`.
+* Added printout of ini file text given parsed options, skips flags.
+* Support for quotes and spaces in ini files
+* Fixes to allow support for Windows (added Appveyor) (Uses `-`, not `/` syntax)
+
+## Version 0.4: Ini support
+
+* Updates to help print
+* Removed `run`, please use `parse` unless you subclass and add it
+* Supports ini files mixed with command line, tested
+* Added Range for further Plumbum compatibility
+* Added function to print out ini file
+
+## Version 0.3: Plumbum compatibility
+
+* Added `->requires`, `->excludes`, and `->envname` from [Plumbum](http://plumbum.readthedocs.io/en/latest/)
+* Supports `->mandatory` from Plubmum
+* More tests for help strings, improvements in formatting
+* Support type and set syntax in positionals help strings
+* Added help groups, with `->group("name")` syntax
+* Added initial support for ini file reading with `add_config` option.
+* Supports GCC 4.7 again
+* Clang 3.5 now required for tests due to googlemock usage, 3.4 should still work otherwise
+* Changes `setup` for an explicit help bool in constructor/`add_subcommand`
+
+## Version 0.2: Leaner and meaner
+
+* Moved to simpler syntax, where `Option` pointers are returned and operated on
+* Removed `make_` style options
+* Simplified Validators, now only requires `->check(function)`
+* Removed Combiners
+* Fixed pointers to Options, stored in `unique_ptr` now
+* Added `Option_p` and `App_p`, mostly for internal use
+* Startup sequence, including help flag, can be modified by subclasses
+
+## Version 0.1: First release
+
+First release before major cleanup. Still has make syntax and combiners; very clever syntax but not the best or most commonly expected way to work.

+
+Thanks for considering to write a Pull Request (PR) for CLI11! Here are a few guidelines to get you started:
+
+Make sure you are comfortable with the license; all contributions are licensed under the original license.
+
+## Adding functionality
+Make sure any new functions you add are are:
+
+* Documented by `///` documentation for Doxygen
+* Mentioned in the instructions in the README, though brief mentions are okay
+* Explained in your PR (or previously explained in an Issue mentioned in the PR)
+* Completely covered by tests
+
+In general, make sure the addition is well thought out and does not increase the complexity of CLI11 if possible.
+
+## Things you should know:
+
+* Once you make the PR, tests will run to make sure your code works on all supported platforms
+* The test coverage is also measured, and that should remain 100%
+* Formatting should be done with clang-format, otherwise the format check will not pass. However, it is trivial to apply this to your PR, so don't worry about this check. If you do have clang-format, just run `scripts/check_style.sh`

+# CLI11: Command line parser for C++11
+
+CLI11 provides all the features you expect in a powerful command line parser, with a beautiful, minimal syntax and no dependencies beyond C++11. It is header only, and comes in a single file form for easy inclusion in projects. It is easy to use for small projects, but powerful enough for complex command line projects, and can be customized for frameworks.
+It is tested on [Travis] and [AppVeyor], and is being included in the [GooFit GPU fitting framework][GooFit]. It was inspired by [`plumbum.cli`][Plumbum] for Python. CLI11 has a user friendly introduction in this README, a more in-depth tutorial [GitBook], as well as [API documentation][api-docs] generated by Travis.
+See the [changelog](./CHANGELOG.md) or [GitHub Releases] for details for current and past releases. Also see the [Version 1.0 post] and [Version 1.3 post] for more information.
+
+You can be notified when new releases are made by subscribing to https://github.com/CLIUtils/CLI11/releases.atom on an RSS reader, like Feedly.
+
+### Why write another CLI parser?
+
+An acceptable CLI parser library should be all of the following:
+
+* Easy to include (i.e., header only, one file if possible, **no external requirements**): While many programs depend on Boost, that should not be a requirement if all you want is CLI parsing.
+* Short Syntax: This is one of the main points of a CLI parser, it should make variables from the command line nearly as easy to define as any other variables. If most of your program is hidden in CLI parsing, this is a problem for readability.
+* C++11 or better: Should work with GCC 4.7+ (such as GCC 4.8 on CentOS 7) or above, or Clang 3.5+, or MSVC 2015+. (Note: for CLI11, Clang 3.4 only fails because of tests, GoogleMock does not support it.)
+* Work on Linux, macOS, and Windows.
+* Well tested using [Travis] (Linux and macOS) and [AppVeyor] (Windows). "Well" is defined as having good coverage measured by [CodeCov].
+* Clear help printing.
+* Nice error messages.
+* Standard shell idioms supported naturally, like grouping flags, a positional separator, etc.
+* Easy to execute, with help, parse errors, etc. providing correct exit and details.
+* Easy to extend as part of a framework that provides "applications" to users.
+* Usable subcommand syntax, with support for multiple subcommands, nested subcommands, and optional fallthrough (explained later).
+* Ability to add a configuration file (`ini` format), and produce it as well.
+* Produce real values that can be used directly in code, not something you have pay compute time to look up, for HPC applications.
+* Work with standard types, simple custom types, and extendible to exotic types.
+* Permissively licensed.
+
+<details><summary>The major CLI parsers for C++ include, with my biased opinions: (click to expand)</summary><p>
+
+| Library | My biased opinion |
+|---------|-------------------|
+| [Boost Program Options] | A great library if you already depend on Boost, but its pre-C++11 syntax is really odd and setting up the correct call in the main function is poorly documented (and is nearly a page of code). A simple wrapper for the Boost library was originally developed, but was discarded as CLI11 became more powerful. The idea of capturing a value and setting it originated with Boost PO. [See this comparison.][cli11-po-compare] |
+| [The Lean Mean C++ Option Parser] | One header file is great, but the syntax is atrocious, in my opinion. It was quite impractical to wrap the syntax or to use in a complex project. It seems to handle standard parsing quite well. |
+| [TCLAP] | The not-quite-standard command line parsing causes common shortcuts to fail. It also seems to be poorly supported, with only minimal bugfixes accepted. Header only, but in quite a few files. Has not managed to get enough support to move to GitHub yet. No subcommands. Produces wrapped values. |
+| [Cxxopts] | C++11, single file, and nice CMake support, but requires regex, therefore GCC 4.8 (CentOS 7 default) does not work. Syntax closely based on Boost PO, so not ideal but familiar. |
+| [DocOpt] | Completely different approach to program options in C++11, you write the docs and the interface is generated. Too fragile and specialized. |
+
+After I wrote this, I also found the following libraries:
+
+| Library | My biased opinion |
+|---------|-------------------|
+| [GFlags] | The Google Commandline Flags library. Uses macros heavily, and is limited in scope, missing things like subcommands. It provides a simple syntax and supports config files/env vars. |
+| [GetOpt] | Very limited C solution with long, convoluted syntax. Does not support much of anything, like help generation. Always available on UNIX, though (but in different flavors). |
+| [ProgramOptions.hxx] | Intresting library, less powerful and no subcommands. Nice callback system. |
+| [Args] | Also interesting, and supports subcommands. I like the optional-like design, but CLI11 is cleaner and provides direct value access, and is less verbose. |
+| [Argument Aggregator] | I'm a big fan of the [fmt] library, and the try-catch statement looks familiar. :thumbsup: Doesn't seem to support subcommands. |
+| [Clara] | Simple library built for the excellent [Catch] testing framework. Unique syntax, limited scope. |
+| [Argh!] | Very minimalistic C++11 parser, single header. Don't have many features. No help generation?!?! At least it's exception-free.|
+| [CLI] | Custom language and parser. Huge build-system overkill for very little benefit. Last release in 2009, but still occasionally active. |
+
+See [Awesome C++] for a less-biased list of parsers.
+
+</p></details>
+<br/>
+
+None of these libraries fulfill all the above requirements, or really even come close. As you probably have already guessed, CLI11 does.
+So, this library was designed to provide a great syntax, good compiler compatibility, and minimal installation fuss.
+
+## Features not supported by this library
+
+There are some other possible "features" that are intentionally not supported by this library:
+
+* Non-standard variations on syntax, like `-long` options. This is non-standard and should be avoided, so that is enforced by this library.
+* Completion of partial options, such as Python's `argparse` supplies for incomplete arguments. It's better not to guess. Most third party command line parsers for python actually reimplement command line parsing rather than using argparse because of this perceived design flaw.
+* In C++14, you could have a set of `callback` methods with differing signatures (tested in a branch). Not deemed worth having a C++14 variation on API and removed.
+* Autocomplete: This might eventually be added to both Plumbum and CLI11, but it is not supported yet.
+* Wide strings / unicode: Since this uses the standard library only, it might be hard to properly implement, but I would be open to suggestions in how to do this.
+
+
+## Installing
+
+To use, there are two methods:
+
+1. Copy `CLI11.hpp` from the [most recent release][Github Releases] into your include directory, and you are set. This is combined from the source files for every release. This includes the entire command parser library, but does not include separate utilities (like `Timer`, `AutoTimer`). The utilities are completely self contained and can be copied separately.
+2. Use `CLI/*.hpp` files. You could check out the repository as a submodule, for example. You can use the `CLI11::CLI11` interface target when linking from `add_subdirectory`. You can also configure and optionally install the project, and then use `find_package(CLI11 CONFIG)` to get the `CLI11::CLI11` target. You can also use [Conan.io][conan-link]. (These are just conveniences to allow you to use your favorite method of managing packages; it's just header only so including the correct path and
+ using C++11 is all you really need.)
+
+To build the tests, checkout the repository and use CMake:
+
+```bash
+mkdir build
+cd build
+cmake ..
+make
+GTEST_COLOR=1 CTEST_OUTPUT_ON_FAILURE=1 make test
+```
+
+## Adding options
+
+To set up, add options, and run, your main function will look something like this:
+
+```cpp
+CLI::App app{"App description"};
+
+std::string filename = "default";
+app.add_option("-f,--file", filename, "A help string");
+
+CLI11_PARSE(app, argc, argv);
+```
+
+<details><summary>Note: If you don't like macros, this is what that macro expands to: (click to expand)</summary><p>
+
+```cpp
+try {
+ app.parse(argc, argv);
+} catch (const CLI::ParseError &e) {
+ return app.exit(e);
+}
+```
+
+The try/catch block ensures that `-h,--help` or a parse error will exit with the correct return code (selected from `CLI::ExitCodes`). (The return here should be inside `main`). You should not assume that the option values have been set inside the catch block; for example, help flags intentionally short-circuit all other processing for speed and to ensure required options and the like do not interfere.
+
+</p></details>
+</br>
+
+
+The initialization is just one line, adding options is just two each. The parse macro is just one line (or 5 for the contents of the macro). After the app runs, the filename will be set to the correct value if it was passed, otherwise it will be set to the default. You can check to see if this was passed on the command line with `app.count("--file")`.
+
+The supported values are:
+
+```cpp
+app.add_option(option_name,
+ variable_to_bind_to, // int, float, vector, or string-like
+ help_string="",
+ default=false)
+
+app.add_complex(... // Special case: support for complex numbers
+
+app.add_flag(option_name,
+ int_or_bool = nothing,
+ help_string="")
+
+app.add_flag_function(option_name,
+ function <void(size_t count)>,
+ help_string="")
+
+app.add_set(option_name,
+ variable_to_bind_to,
+ set_of_possible_options,
+ help_string="",
+ default=false)
+
+app.add_set_ignore_case(... // String only
+
+App* subcom = app.add_subcommand(name, discription);
+```
+
+An option name must start with a alphabetic character or underscore. For long options, anything but an equals sign or a comma is valid after that. Names are given as a comma separated string, with the dash or dashes. An option or flag can have as many names as you want, and afterward, using `count`, you can use any of the names, with dashes as needed, to count the options. One of the names is allowed to be given without proceeding dash(es); if present the option is a positional option, and that name will be used on help line for its positional form. If you want the default value to print in the help description, pass in `true` for the final parameter for `add_option` or `add_set`. The set options allow your users to pick from a set of predefined options.
+
+On a C++14 compiler, you can pass a callback function directly to `.add_flag`, while in C++11 mode you'll need to use `.add_flag_function` if you want a callback function. The function will be given the number of times the flag was passed. You can throw a relevant `CLI::ParseError` to signal a failure.
+
+### Example
+
+* `"one,-o,--one"`: Valid as long as not a flag, would create an option that can be specified positionally, or with `-o` or `--one`
+* `"this"` Can only be passed positionally
+* `"-a,-b,-c"` No limit to the number of non-positional option names
+
+
+The add commands return a pointer to an internally stored `Option`. If you set the final argument to true, the default value is captured and printed on the command line with the help flag. This option can be used directly to check for the count (`->count()`) after parsing to avoid a string based lookup. Before parsing, you can set the following options:
+
+* `->required()`: The program will quit if this option is not present. This is `mandatory` in Plumbum, but required options seems to be a more standard term. For compatibility, `->mandatory()` also works.
+* `->expected(N)`: Take `N` values instead of as many as possible, only for vector args. If negative, require at least `-N`.
+* `->needs(opt)`: This option requires another option to also be present, opt is an `Option` pointer.
+* `->excludes(opt)`: This option cannot be given with `opt` present, opt is an `Option` pointer.
+* `->envname(name)`: Gets the value from the environment if present and not passed on the command line.
+* `->group(name)`: The help group to put the option in. No effect for positional options. Defaults to `"Options"`. `""` will not show up in the help print (hidden).
+* `->ignore_case()`: Ignore the case on the command line (also works on subcommands, does not affect arguments).
+* `->multi_option_policy(CLI::MultiOptionPolicy::Throw)`: Set the multi-option policy. Shortcuts available: `->take_last()`, `->take_first()`, and `->join()`. This will only affect options expecting 1 argument or bool flags (which always default to take last).
+* `->check(CLI::ExistingFile)`: Requires that the file exists if given.
+* `->check(CLI::ExistingDirectory)`: Requires that the directory exists.
+* `->check(CLI::ExistingPath)`: Requires that the path (file or directory) exists.
+* `->check(CLI::NonexistentPath)`: Requires that the path does not exist.
+* `->check(CLI::Range(min,max))`: Requires that the option be between min and max (make sure to use floating point if needed). Min defaults to 0.
+* `->transform(std::string(std::string))`: Converts the input string into the output string, in-place in the parsed options.
+* `->configurable(false)`: Disable this option from being in an ini configuration file.
+
+These options return the `Option` pointer, so you can chain them together, and even skip storing the pointer entirely. Check takes any function that has the signature `void(const std::string&)`; it should throw a `ValidationError` when validation fails. The help message will have the name of the parent option prepended. Since `check` and `transform` use the same underlying mechanism, you can chain as many as you want, and they will be executed in order. If you just want to see the unconverted values, use `.results()` to get the `std::vector<std::string>` of results.
+
+
+On the command line, options can be given as:
+
+* `-a` (flag)
+* `-abc` (flags can be combined)
+* `-f filename` (option)
+* `-ffilename` (no space required)
+* `-abcf filename` (flags and option can be combined)
+* `--long` (long flag)
+* `--file filename` (space)
+* `--file=filename` (equals)
+
+Extra positional arguments will cause the program to exit, so at least one positional option with a vector is recommended if you want to allow extraneous arguments.
+If you set `.allow_extras()` on the main `App`, you will not get an error. You can access the missing options using `remaining` (if you have subcommands, `app.remaining(true)` will get all remaining options, subcommands included).
+
+You can access a vector of pointers to the parsed options in the original order using `parse_order()`.
+If `--` is present in the command line,
+everything after that is positional only.
+
+
+
+## Subcommands
+
+Subcommands are supported, and can be nested infinitely. To add a subcommand, call the `add_subcommand` method with a name and an optional description. This gives a pointer to an `App` that behaves just like the main app, and can take options or further subcommands. Add `->ignore_case()` to a subcommand to allow any variation of caps to also be accepted. Children inherit the current setting from the parent. You cannot add multiple matching subcommand names at the same level (including ignore
+case).
+
+If you want to require that at least one subcommand is given, use `.require_subcommand()` on the parent app. You can optionally give an exact number of subcommands to require, as well. If you give two arguments, that sets the min and max number allowed.
+0 for the max number allowed will allow an unlimited number of subcommands. As a handy shortcut, a single negative value N will set "up to N" values. Limiting the maximimum number allows you to keep arguments that match a previous
+subcommand name from matching.
+
+If an `App` (main or subcommand) has been parsed on the command line, `->parsed` will be true (or convert directly to bool).
+All `App`s have a `get_subcommands()` method, which returns a list of pointers to the subcommands passed on the command line. A `got_subcommand(App_or_name)` method is also provided that will check to see if an `App` pointer or a string name was collected on the command line.
+
+For many cases, however, using an app's callback may be easier. Every app executes a callback function after it parses; just use a lambda function (with capture to get parsed values) to `.set_callback`. If you throw `CLI::Success` or `CLI::RuntimeError(return_value)`, you can
+even exit the program through the callback. The main `App` has a callback slot, as well, but it is generally not as useful.
+You are allowed to throw `CLI::Success` in the callbacks.
+Multiple subcommands are allowed, to allow [`Click`][Click] like series of commands (order is preserved).
+
+There are several options that are supported on the main app and subcommands. These are:
+
+* `.ignore_case()`: Ignore the case of this subcommand. Inherited by added subcommands, so is usually used on the main `App`.
+* `.fallthrough()`: Allow extra unmatched options and positionals to "fall through" and be matched on a parent command. Subcommands always are allowed to fall through.
+* `.require_subcommand()`: Require 1 or more subcommands.
+* `.require_subcommand(N)`: Require `N` subcommands if `N>0`, or up to `N` if `N<0`. `N=0` resets to the default 0 or more.
+* `.require_subcommand(min, max)`: Explicitly set min and max allowed subcommands. Setting `max` to 0 is unlimited.
+* `.add_subcommand(name, description="")` Add a subcommand, returns a pointer to the internally stored subcommand.
+* `.got_subcommand(App_or_name)`: Check to see if a subcommand was received on the command line
+* `.get_subcommands()`: The list of subcommands given on the command line
+* `.get_parent()`: Get the parent App or nullptr if called on master App **Coming in version 1.4**
+* `.parsed()`: True if this subcommand was given on the command line
+* `.set_callback(void() function)`: Set the callback that runs at the end of parsing. The options have already run at this point.
+* `.allow_extras()`: Do not throw an error if extra arguments are left over
+* `.prefix_command()`: Like `allow_extras`, but stop immediately on the first unrecognised item. It is ideal for allowing your app or subcommand to be a "prefix" to calling another app.
+* `.set_footer(message)`: Set text to appear at the bottom of the help string.
+* `.set_failure_message(func)`: Set the failure message function. Two provided: `CLI::FailureMessage::help` and `CLI::FailureMessage::simple` (the default).
+* `.group(name)`: Set a group name, defaults to `"Subcommands"`. Setting `""` will be hide the subcommand.
+
+> Note: if you have a fixed number of required positional options, that will match before subcommand names.
+
+## Configuration file
+
+```cpp
+app.set_config(option_name="",
+ default_file_name="",
+ help_string="Read an ini file",
+ required=false)
+```
+
+If this is called with no arguments, it will remove the configuration file option (like `set_help_flag`). Setting a configuration option is special. If it is present, it will be read along with the normal command line arguments. The file will be read if it exists, and does not throw an error unless `required` is `true`. Configuration files are in `ini` format. An example of a file:
+
+```ini
+; Commments are supported, using a ;
+; The default section is [default], case insensitive
+
+value = 1
+str = "A string"
+vector = 1 2 3
+
+; Section map to subcommands
+[subcommand]
+in_subcommand = Wow
+sub.subcommand = true
+```
+
+Spaces before and after the name and argument are ignored. Multiple arguments are separated by spaces. One set of quotes will be removed, preserving spaces (the same way the command line works). Boolean options can be `true`, `on`, `1`, `yes`; or `false`, `off`, `0`, `no` (case insensitive). Sections (and `.` separated names) are treated as subcommands (note: this does not mean that subcommand was passed, it just sets the "defaults". To print a configuration file from the passed
+arguments, use `.config_to_str(default_also=false, prefix="", write_description=false)`, where `default_also` will also show any defaulted arguments, `prefix` will add a prefix, and `write_description` will include option descriptions.
+
+## Inheriting defaults
+
+Many of the defaults for subcommands and even options are inherited from their creators. The inherited default values for subcommands are `allow_extras`, `prefix_command`, `ignore_case`, `fallthrough`, `group`, `footer`, and maximum number of required subcommands. The help flag existence, name, and description are inherited, as well.
+
+Options have defaults for `group`, `required`, `multi_option_policy`, and `ignore_case`. To set these defaults, you should set the `option_defaults()` object, for example:
+
+```cpp
+app.option_defaults()->required();
+// All future options will be required
+```
+
+The default settings for options are inherited to subcommands, as well.
+
+## Subclassing
+
+The App class was designed allow toolkits to subclass it, to provide preset default options (see above) and setup/teardown code. Subcommands remain an unsubclassed `App`, since those are not expected to need setup and teardown. The default `App` only adds a help flag, `-h,--help`, than can removed/replaced using `.set_help_flag(name, help_string)`. You can remove options if you have pointers to them using `.remove_option(opt)`. You can add a `pre_callback` override to customize the after parse
+but before run behavior, while
+still giving the user freedom to `set_callback` on the main app.
+
+The most important parse function is `parse(std::vector<std::string>)`, which takes a reversed list of arguments (so that `pop_back` processes the args in the correct order). `get_help_ptr` and `get_config_ptr` give you access to the help/config option pointers. The standard `parse` manually sets the name from the first argument, so it should not be in this vector.
+
+Also, in a related note, the `App` you get a pointer to is stored in the parent `App` in a `unique_ptr`s (like `Option`s) and are deleted when the main `App` goes out of scope.
+
+
+## How it works
+
+Every `add_` option you have seen so far depends on one method that takes a lambda function. Each of these methods is just making a different lambda function with capture to populate the option. The function has full access to the vector of strings, so it knows how many times an option was passed or how many arguments it received (flags add empty strings to keep the counts correct). The lambda returns `true` if it could validate the option strings, and
+`false` if it failed. If you wanted to extend this to support a new type, just use a lambda. An example of a new parser for `complex<double>` that supports all of the features of a standard `add_options` call is in [one of the tests](./tests/NewParseTest.cpp). A simpler example is shown below:
+
+### Example
+
+```cpp
+app.add_option("--fancy-count", [](std::vector<std::string> val){
+ std::cout << "This option was given " << val.size() << " times." << std::endl
+ });
+```
+
+## Utilities
+
+There are a few other utilities that are often useful in CLI programming. These are in separate headers, and do not appear in `CLI11.hpp`, but are completely independent and can be used as needed. The `Timer`/`AutoTimer` class allows you to easily time a block of code, with custom print output.
+
+```cpp
+{
+CLI::AutoTimer timer {"My Long Process", CLI::Timer::Big};
+some_long_running_process();
+}
+```
+
+This will create a timer with a title (default: `Timer`), and will customize the output using the predefined `Big` output (default: `Simple`). Because it is an `AutoTimer`, it will print out the time elapsed when the timer is destroyed at the end of the block. If you use `Timer` instead, you can use `to_string` or `std::cout << timer << std::endl;` to print the time. The print function can be any function that takes two strings, the title and the time, and returns a formatted
+string for printing.
+
+## Other libraries
+
+If you use the excellent [Rang] library to add color to your terminal in a safe, multi-platform way, you can combine it with CLI11 nicely:
+
+```cpp
+std::atexit([](){std::cout << rang::style::reset;});
+try {
+ app.parse(argc, argv);
+} catch (const CLI::ParseError &e) {
+ std::cout << (e.get_exit_code()==0 ? rang::fg::blue : rang::fg::red);
+ return app.exit(e);
+}
+```
+
+This will print help in blue, errors in red, and will reset before returning the terminal to the user.
+
+If you are on a Unix-like system, and you'd like to handle control-c and color, you can add:
+
+```cpp
+ #include <csignal>
+ void signal_handler(int s) {
+ std::cout << std::endl << rang::style::reset << rang::fg::red << rang::fg::bold;
+ std::cout << "Control-C detected, exiting..." << rang::style::reset << std::endl;
+ std::exit(1); // will call the correct exit func, no unwinding of the stack though
+ }
+```
+
+And, in your main function:
+
+```cpp
+ // Nice Control-C
+ struct sigaction sigIntHandler;
+ sigIntHandler.sa_handler = signal_handler;
+ sigemptyset(&sigIntHandler.sa_mask);
+ sigIntHandler.sa_flags = 0;
+ sigaction(SIGINT, &sigIntHandler, nullptr);
+```

+# USAGE:
+
+# 0. (Mac only) If you use Xcode 5.1 make sure to patch geninfo as described here:
+# http://stackoverflow.com/a/22404544/80480
+#
+# 1. Copy this file into your cmake modules path.
+#
+# 2. Add the following line to your CMakeLists.txt:
+# INCLUDE(CodeCoverage)
+#
+# 3. Set compiler flags to turn off optimization and enable coverage:
+# SET(CMAKE_CXX_FLAGS "-g -O0 -fprofile-arcs -ftest-coverage")
+# SET(CMAKE_C_FLAGS "-g -O0 -fprofile-arcs -ftest-coverage")
+#
+# 3. Use the function SETUP_TARGET_FOR_COVERAGE to create a custom make target
+# which runs your test executable and produces a lcov code coverage report:
+# Example:
+# SETUP_TARGET_FOR_COVERAGE(
+# my_coverage_target # Name for custom target.
+# test_driver # Name of the test driver executable that runs the tests.
+# # NOTE! This should always have a ZERO as exit code
+# # otherwise the coverage generation will not complete.
+# coverage # Name of output directory.
+# )
+#

+# MODULE: DownloadProject
+#
+# PROVIDES:
+# download_project( PROJ projectName
+# [PREFIX prefixDir]
+# [DOWNLOAD_DIR downloadDir]
+# [SOURCE_DIR srcDir]
+# [BINARY_DIR binDir]
+# [QUIET]
+# ...
+# )
+#
+# Provides the ability to download and unpack a tarball, zip file, git repository,
+# etc. at configure time (i.e. when the cmake command is run). How the downloaded
+# and unpacked contents are used is up to the caller, but the motivating case is
+# to download source code which can then be included directly in the build with
+# add_subdirectory() after the call to download_project(). Source and build
+# directories are set up with this in mind.
+#
+# The PROJ argument is required. The projectName value will be used to construct
+# the following variables upon exit (obviously replace projectName with its actual
+# value):
+#
+# projectName_SOURCE_DIR
+# projectName_BINARY_DIR
+#
+# The SOURCE_DIR and BINARY_DIR arguments are optional and would not typically
+# need to be provided. They can be specified if you want the downloaded source
+# and build directories to be located in a specific place. The contents of
+# projectName_SOURCE_DIR and projectName_BINARY_DIR will be populated with the
+# locations used whether you provide SOURCE_DIR/BINARY_DIR or not.
+#
+# The DOWNLOAD_DIR argument does not normally need to be set. It controls the
+# location of the temporary CMake build used to perform the download.
+#
+# The PREFIX argument can be provided to change the base location of the default
+# values of DOWNLOAD_DIR, SOURCE_DIR and BINARY_DIR. If all of those three arguments
+# are provided, then PREFIX will have no effect. The default value for PREFIX is
+# CMAKE_BINARY_DIR.
+#
+# The QUIET option can be given if you do not want to show the output associated
+# with downloading the specified project.
+#
+# In addition to the above, any other options are passed through unmodified to
+# ExternalProject_Add() to perform the actual download, patch and update steps.
+# The following ExternalProject_Add() options are explicitly prohibited (they
+# are reserved for use by the download_project() command):
+#
+# CONFIGURE_COMMAND
+# BUILD_COMMAND
+# INSTALL_COMMAND
+# TEST_COMMAND
+#
+# Only those ExternalProject_Add() arguments which relate to downloading, patching
+# and updating of the project sources are intended to be used. Also note that at
+# least one set of download-related arguments are required.
+#
+# If using CMake 3.2 or later, the UPDATE_DISCONNECTED option can be used to
+# prevent a check at the remote end for changes every time CMake is run
+# after the first successful download. See the documentation of the ExternalProject
+# module for more information. It is likely you will want to use this option if it
+# is available to you. Note, however, that the ExternalProject implementation contains
+# bugs which result in incorrect handling of the UPDATE_DISCONNECTED option when
+# using the URL download method or when specifying a SOURCE_DIR with no download
+# method. Fixes for these have been created, the last of which is scheduled for
+# inclusion in CMake 3.8.0. Details can be found here:
+#
+# https://gitlab.kitware.com/cmake/cmake/commit/bdca68388bd57f8302d3c1d83d691034b7ffa70c
+# https://gitlab.kitware.com/cmake/cmake/issues/16428
+#
+# If you experience build errors related to the update step, consider avoiding
+# the use of UPDATE_DISCONNECTED.

+# Introduction
+
+This is the Doxygen API documentation for CLI11 parser. There is a friendly introduction to CLI11 on the [Github page](https://github.com/CLIUtils/CLI11).
+
+The main classes are:
+
+| Name | Where used |
+|---------------|-------------------------------------|
+|CLI::Option | Options, stored in the app |
+|CLI::App | The main application or subcommands |
+|CLI::ExitCode | A scoped enum with exit codes |
+|CLI::Timer | A timer class, only in CLI/Timer.hpp (not in `CLI11.hpp`) |
+|CLI::AutoTimer | A timer that prints on deletion |
+
+
+Groups of related topics:
+
+| Name | Description |
+|----------------------|------------------------------------------------|
+| @ref error_group | Errors that can be thrown |
+| @ref validator_group | Common validators used in CLI::Option::check() |
+
