 ExtUtils::MM::Utils

If you cannot afford depending on ExtUtils::MakeMaker, you can
depend on ExtUtils::MM::Utils instead.

+=head1 NAME
+
+ExtUtils::MM::Utils - ExtUtils::MM methods without dependency on ExtUtils::MakeMaker
+
+=head1 SYNOPSIS
+
+    require ExtUtils::MM::Utils;
+    MM->maybe_command($file);
+
+=head1 DESCRIPTION
+
+This is a collection of L<ExtUtils::MM> subroutines that are used by many
+other modules but that do not need full-featured L<ExtUtils::MakeMaker>. The
+issue with L<ExtUtils::MakeMaker> is it pulls in Perl header files and that is
+an overkill for small subroutines.
+
+An example is the L<IPC::Cmd> that caused installing GCC just because of
+three-line I<maybe_command()> from L<ExtUtils::MM_Unix>.
+
+The intentions is to use L<ExtUtils::MM::Utils> instead of
+L<ExtUtils::MakeMaker> for these trivial methods. You can still call them via
+L<MM> class name.
+
+=head1 METHODS
+

+
+=item maybe_command
+
+Returns true, if the argument is likely to be a command.

+=head1 BUGS
+
+These methods are copied from L<ExtUtils::MM_Unix>. Other operating systems
+are not supported yet. The reason is this
