I guess it depends on your definition of "pretty small files" since the
g++ manpage in question is 127k gzipped (nearly 500k uncompressed).
If you have most everything installed we're still probably talking about
less than 100M of disk savings, but it's better than nothing--especially
on old machines like my laptop with a 1.5G disk. :)
