+ * Parse the plugin contents to retrieve plugin's metadata.
+ *
+ * The metadata of the plugin's data searches for the following in the plugin's
+ * header. All plugin data must be on its own line. For plugin description, it
+ * must not have any newlines or only parts of the description will be displayed
+ * and the same goes for the plugin data. The below is formatted for printing.
+ *
+ * <code>
+ * /*
+ * Plugin Name: Name of Plugin
+ * Plugin URI: Link to plugin information
+ * Description: Plugin Description
+ * Author: Plugin author's name
+ * Author URI: Link to the author's web site
+ * Version: Must be set in the plugin for WordPress 2.3+
+ * Text Domain: Optional. Unique identifier, should be same as the one used in
+ * plugin_text_domain()
+ * Domain Path: Optional. Only useful if the translations are located in a
+ * folder above the plugin's base path. For example, if .mo files are
+ * located in the locale folder then Domain Path will be "/locale/" and
+ * must have the first slash. Defaults to the base folder the plugin is
+ * located in.
+ * * / # Remove the space to close comment
+ * </code>
+ *
+ * Plugin data returned array contains the following:
+ * 'Name' - Name of the plugin, must be unique.
+ * 'Title' - Title of the plugin and the link to the plugin's web site.
+ * 'Description' - Description of what the plugin does and/or notes
+ * from the author.
+ * 'Author' - The author's name
+ * 'AuthorURI' - The authors web site address.
+ * 'Version' - The plugin version number.
+ * 'PluginURI' - Plugin web site address.
+ * 'TextDomain' - Plugin's text domain for localization.
+ * 'DomainPath' - Plugin's relative directory path to .mo files.
+ *
+ * Some users have issues with opening large files and manipulating the contents
+ * for want is usually the first 1kiB or 2kiB. This function stops pulling in
+ * the plugin contents when it has all of the required plugin data.
+ *
+ * The first 8kiB of the file will be pulled in and if the plugin data is not
+ * within that first 8kiB, then the plugin author should correct their plugin
+ * and move the plugin data headers to the top.
+ *
+ * The plugin file is assumed to have permissions to allow for scripts to read
+ * the file. This is not checked however and the file is only opened for
+ * reading.
+ *
