/**
* Create a POT file for a WordPress project.
*
* Scans PHP, Blade-PHP and JavaScript files for translatable strings, as well as theme stylesheets and plugin files
* if the source directory is detected as either a plugin or theme.
*
* ## OPTIONS
*
* <source>
* : Directory to scan for string extraction.
*
* [<destination>]
* : Name of the resulting POT file.
*
* [--slug=<slug>]
* : Plugin or theme slug. Defaults to the source directory's basename.
*
* [--domain=<domain>]
* : Text domain to look for in the source code, unless the `--ignore-domain` option is used.
* By default, the "Text Domain" header of the plugin or theme is used.
* If none is provided, it falls back to the project slug.
*
* [--ignore-domain]
* : Ignore the text domain completely and extract strings with any text domain.
*
* [--merge[=<paths>]]
* : Comma-separated list of POT files whose contents should be merged with the extracted strings.
* If left empty, defaults to the destination POT file. POT file headers will be ignored.
*
* [--subtract=<paths>]
* : Comma-separated list of POT files whose contents should act as some sort of denylist for string extraction.
* Any string which is found on that denylist will not be extracted.
* This can be useful when you want to create multiple POT files from the same source directory with slightly
* different content and no duplicate strings between them.
*
* [--subtract-and-merge]
* : Whether source code references and comments from the generated POT file should be instead added to the POT file
* used for subtraction. Warning: this modifies the files passed to `--subtract`!
*
* [--include=<paths>]
* : Comma-separated list of files and paths that should be used for string extraction.
* If provided, only these files and folders will be taken into account for string extraction.
* For example, `--include="src,my-file.php` will ignore anything besides `my-file.php` and files in the `src`
* directory. Simple glob patterns can be used, i.e. `--include=foo-*.php` includes any PHP file with the `foo-`
* prefix. Leading and trailing slashes are ignored, i.e. `/my/directory/` is the same as `my/directory`.
*
* [--exclude=<paths>]
* : Comma-separated list of files and paths that should be skipped for string extraction.
* For example, `--exclude=.github,myfile.php` would ignore any strings found within `myfile.php` or the `.github`
* folder. Simple glob patterns can be used, i.e. `--exclude=foo-*.php` excludes any PHP file with the `foo-`
* prefix. Leading and trailing slashes are ignored, i.e. `/my/directory/` is the same as `my/directory`. The
* following files and folders are always excluded: node_modules, .git, .svn, .CVS, .hg, vendor, *.min.js.
*
* [--headers=<headers>]
* : Array in JSON format of custom headers which will be added to the POT file. Defaults to empty array.
*
* [--location]
* : Whether to write `#: filename:line` lines.
* Defaults to true, use `--no-location` to skip the removal.
* Note that disabling this option makes it harder for technically skilled translators to understand each message’s context.
*
* [--skip-js]
* : Skips JavaScript string extraction. Useful when this is done in another build step, e.g. through Babel.
*
* [--skip-php]
* : Skips PHP string extraction.
*
* [--skip-blade]
* : Skips Blade-PHP string extraction.
*
* [--skip-block-json]
* : Skips string extraction from block.json files.
*
* [--skip-theme-json]
* : Skips string extraction from theme.json files.
*
* [--skip-audit]
* : Skips string audit where it tries to find possible mistakes in translatable strings. Useful when running in an
* automated environment.
*
* [--file-comment=<file-comment>]
* : String that should be added as a comment to the top of the resulting POT file.
* By default, a copyright comment is added for WordPress plugins and themes in the following manner:
*
* ```
* Copyright (C) 2018 Example Plugin Author
* This file is distributed under the same license as the Example Plugin package.
* ```
*
* If a plugin or theme specifies a license in their main plugin file or stylesheet, the comment looks like
* this:
*
* ```
* Copyright (C) 2018 Example Plugin Author
* This file is distributed under the GPLv2.
* ```
*
* [--package-name=<name>]
* : Name to use for package name in the resulting POT file's `Project-Id-Version` header.
* Overrides plugin or theme name, if applicable.
*
* ## EXAMPLES
*
* # Create a POT file for the WordPress plugin/theme in the current directory.
* $ wp i18n make-pot . languages/my-plugin.pot
*
* # Create a POT file for the continents and cities list in WordPress core.
* $ wp i18n make-pot . continents-and-cities.pot --include="wp-admin/includes/continents-cities.php" --ignore-domain
*
* # Create a POT file for the WordPress theme in the current directory with custom headers.
* $ wp i18n make-pot . languages/my-theme.pot --headers='{"Report-Msgid-Bugs-To":"https://github.com/theme-author/my-theme/","POT-Creation-Date":""}'
