=head1 DESCRIPTION
The module is used to replace common UNIX commands. In all cases the
functions work from @ARGV rather than taking arguments. This makes
-them easier to deal with in Makefiles.
+them easier to deal with in Makefiles. Call them like this:
perl -MExtUtils::Command -e some_command some files to work on
-I<NOT>
+and I<NOT> like this:
perl -MExtUtils::Command -e 'some_command qw(some files to work on)'
+For that use L<Shell::Command>.
+
Filenames with * and ? will be glob expanded.
