Pardon?  There's about a zillion TIFFs.  Do you mean revision 4, revision 
5, revision 6, class B, class F?  Big-endian or little-endian?  Do you 
support image negatives, rotation, bitmaps, RGB, multiple strips, RLE 
compression, fax group 3 compression, fax group 4 compression, no 
compression, word-boundary compression, PackBits compression?  I guess it 
is well-defined but "not too hard" isn't the description I'd choose.

That's the trouble with tagged file formats -- very flexible but a pain 
in the ass to support if people can't resist throwing in features.

$on_a_mac = defined($MacPerl::Version);


And while I'm at it, a third topic, a feature request:

How about cmd-D meaning "Don't Save" in the close-dirty dialog box?
