-% ExpandFilenames() checks each argument of the command line vector and
-% expands it if they have a wildcard character. For example, *.jpg might
-% expand to: bird.jpg rose.jpg tiki.jpg.
+% ExpandFilenames() checks each argument of the given argument array, and
+% expands it if they have a wildcard character.
+%
+% Any coder prefix (EG: 'coder:filename') or read modifier postfix (EG:
+% 'filename[...]') are ignored during the file the expansion, but will be
+% included in the final argument. If no filename matching the meta-character
+% 'glob' is found the original argument is returned.
+%
+% For example, an argument of '*.gif[20x20]' will be replaced by the list
+% 'abc.gif[20x20]', 'foobar.gif[20x20]', 'xyzzy.gif[20x20]'
+% if such filenames exist, (in the current directory in this case).
+%
+% Meta-characters handled...
+% @ read a list of filenames (no further expansion performed)
+% ~ At start of filename expands to HOME environemtn variable
+% * matches any string including an empty string
+% ? matches by any single character
+%
+% WARNING: filenames starting with '.' (hidden files in a UNIX file system)
+% will never be expanded. Attempting to epand '.*' will produce no change.
+%
+% Expansion is ignored for coders "label:" "caption:" "pango:" and "vid:".
+% Which provide their own '@' meta-character handling.
+%
+% You can see the results of the expansion using "Configure" log
+% events.
+%
+%
+% The returned list should be freed using DestroyStringList().
+%
+% However the strings in the original pointed to argv are not
+% freed (TO BE CHECKED). So a copy of the original pointer (and count)
+% should be kept separate if they need to be freed later.
