  * This is used as a fallback to mime.types files.
  * An extensive list of well known mime types is provided by
  * the file mime.types in the includes directory.
+ * 
+ * This list concatenated with mime.types is used to create a mime <-> ext
+ * map. Each line contains a mime type followed by a space separated list of
+ * extensions. If multiple extensions for a single mime type exist or if 
+ * multiple mime types exist for a single extension then in most cases
+ * MediaWiki assumes that the first extension following the mime type is the
+ * canonical extension, and the first time a mime type appears for a certain
+ * extension is considered the canonical mime type.
+ * 
+ * (Note that appending $wgMimeTypeFile to the end of MM_WELL_KNOWN_MIME_TYPES
+ * sucks because you can't redefine canonical types. This could be fixed by 
+ * appending MM_WELL_KNOWN_MIME_TYPES behind $wgMimeTypeFile, but who knows
+ * what will break? In practice this probably isn't a problem anyway -- Bryan)
