Since these are comments, you'll have to parse the content yourself.
My advice is to open a stream for reading via 'openr' and read the
lines of the header via 'readline', then get all the rest of the data
via read_nested_list(S) where S is the stream. 

To extract the foo=bar stuff, you can call 'substring' and then split
the result via 'split'. You can parse numbers via 'parse_string'
although I guess you'll need to assign ibase:16 before parsing RGBident.

There is a regular expression package in Maxima, although it is not as
powerful as the ones in other languages, and it is Lisp-only. But I'll
explain how you could use it for this if you're interested.
