=head1 DESCRIPTION
-The module is used in Win32 port to replace common UNIX commands.
-Most commands are wrapers on generic modules File::Path and File::Basename.
+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.
+
+ perl -MExtUtils::Command -e some_command some files to work on
+
+I<NOT>
+
+ perl -MExtUtils::Command -e 'some_command qw(some files to work on)'
+
+Filenames with * and ? will be glob expanded.
