There's a useful perl script called "rename", which has been shipped
as an example in the perl distribution for many years, though we don't
install it from pkgsrc.  If you install it by hand ("make extract"
under pkgsrc/lang/perl5, and then look in the work/perl-<version>/eg
subdirectory) then you will be able to do stuff like

	rename 's/.p$/.pas$/' *.p

to rename all your Pascal source code from *.p to *.pas, or

	rename 'tr/A-Z/a-z/' *

to change all uppercase A-Z to lowercase a-z.
