=head1 NAME
ExtUtils::Command::MM - Commands for the MM's to use in Makefiles
=head1 SYNOPSIS
perl "-MExtUtils::Command::MM" -e "function" "--" arguments...
=head1 DESCRIPTION
B<FOR INTERNAL USE ONLY!> The interface is not stable.
ExtUtils::Command::MM encapsulates code which would otherwise have to
be done with large "one" liners.
Any $(FOO) used in the examples are make variables, not Perl.

=item B<test_harness>
test_harness($verbose, @test_libs);
Runs the tests on @ARGV via Test::Harness passing through the $verbose
flag. Any @test_libs will be unshifted onto the test's @INC.
@test_libs are run in alphabetical order.

# or args on @ARGV
pod2man() is a function performing most of the duties of the pod2man
program. Its arguments are exactly the same as pod2man as of 5.8.0
with the addition of:
--perm_rw octal permission to set the resulting manpage to
And the removal of:
--verbose/-v
--help/-h
If no arguments are given to pod2man it will read from @ARGV.
If Pod::Man is unavailable, this function will warn and return undef.

perl "-MExtUtils::Command::MM" -e perllocal_install

Prints a fragment of POD suitable for appending to perllocal.pod.
Arguments are read from @ARGV.
'type' is the type of what you're installing. Usually 'Module'.
'module name' is simply the name of your module. (Foo::Bar)
Key/value pairs are extra information about the module. Fields include:
installed into which directory your module was out into
LINKTYPE dynamic or static linking
VERSION module version number
EXE_FILES any executables installed in a space separated
list

uninstallation.
