+dnl # The META file format is as follows:
+dnl # ^[ ]*KEY:[ \t]+VALUE$
+dnl #
+dnl # In other words:
+dnl # - KEY is separated from VALUE by a colon and one or more spaces/tabs.
+dnl # - KEY and VALUE are case sensitive.
+dnl # - Leading spaces are ignored.
+dnl # - First match wins for duplicate keys.
+dnl #
+dnl # A line can be commented out by preceding it with a '#' (or technically
+dnl # any non-space character since that will prevent the regex from
+dnl # matching).
+dnl #
+dnl # WARNING:
+dnl # Placing a colon followed by a space or tab (ie, ":[ \t]+") within the
+dnl # VALUE will prematurely terminate the string since that sequence is
+dnl # used as the awk field separator.
+dnl #
+dnl # KEYS:
+dnl # The following META keys are recognized:
+dnl # Name, Version, Release, Date, Author, LT_Current, LT_Revision, LT_Age
