/**
 * Composer plugin that allows merging multiple composer.json files.
 *
 * When installed, this plugin will look for a "merge-plugin" key in the
 * composer configuration's "extra" section. The value for this key is
 * a set of options configuring the plugin.
 *
 * An "include" setting is required. The value of this setting can be either
 * a single value or an array of values. Each value is treated as a glob()
 * pattern identifying additional composer.json style configuration files to
 * merge into the configuration for the current compser execution.
 *
 * The "autoload", "autoload-dev", "conflict", "provide", "replace",
 * "repositories", "require", "require-dev", and "suggest" sections of the
 * found configuration files will be merged into the root package
 * configuration as though they were directly included in the top-level
 * composer.json file.
 *
 * If included files specify conflicting package versions for "require" or
 * "require-dev", the normal Composer dependency solver process will be used
 * to attempt to resolve the conflict. Specifying the 'replace' key as true will
 * change this default behaviour so that the last-defined version of a package
 * will win, allowing for force-overrides of package defines.
 *
 * By default the "extra" section is not merged. This can be enabled by
 * setitng the 'merge-extra' key to true. In normal mode, when the same key is
 * found in both the original and the imported extra section, the version in
 * the original config is used and the imported version is skipped. If
 * 'replace' mode is active, this behaviour changes so the imported version of
 * the key is used, replacing the version in the original config.
