/**
- * Returns a list of information about file t ypes based on extensions
+ * Returns a list of information about file types based on extensions.
+ *
+ * The following elements expected in value array for each extension:
+ * 'type' - mimetype
+ * 'icon' - location of the icon file. If value is FILENAME, then either pix/f/FILENAME.gif
+ * or pix/f/FILENAME.png must be present in moodle and contain 16x16 filetype icon;
+ * also files with bigger sizes under names
+ * FILENAME-24, FILENAME-32, FILENAME-64, FILENAME-128, FILENAME-256 are recommended.
+ * 'groups' (optional) - array of filetype groups this filetype extension is part of;
+ * commonly used in moodle the following groups:
+ * - web_image - image that can be included as <img> in HTML
+ * - image - image that we can parse using GD to find it's dimensions, also used for portfolio format
+ * - video - file that can be imported as video in text editor
+ * - audio - file that can be imported as audio in text editor
+ * - archive - we can extract files from this archive
+ * - spreadsheet - used for portfolio format
+ * - document - used for portfolio format
+ * - presentation - used for portfolio format
+ * 'string' (optional) - the name of the string from lang/en/mimetypes.php that displays
+ * human-readable description for this filetype;
+ * Function {@link get_mimetype_description()} first looks at the presence of string for
+ * particular mimetype (value of 'type'), if not found looks for string specified in 'string'
+ * attribute, if not found returns the value of 'type';
+ * 'defaulticon' (boolean, optional) - used by function {@link file_mimetype_icon()} to find
+ * an icon for mimetype. If an entry with 'defaulticon' is not found for a particular mimetype,
+ * this function will return first found icon; Especially usefull for types such as 'text/plain'
*
* @category files
* @return array List of information about file types based on extensions.
* from 'element name' to data. Current element names are 'type' and 'icon'.
* Unknown types should use the 'xxx' entry which includes defaults.
