In true Perl spirit (TMTOWTDI, etc.) I usually map{} arrays instead of
iterating over them with for loops and am a great fan of xargs:

	find . -name "*.TTF" | \
	xargs perl -e 'map{rename($_,lc) || warn "$_: $!\n"} @ARGV'

Cool trick though.  It has been my favorite way of mass-renaming files
for a long time.  It's faster to check and harder to get wrong than the
equivalent echo/sed/mv stuff in sh(1).
