=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
=over 4
=item maybe_command
Returns true, if the argument is likely to be a command.

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