=head1 NAME
ExtUtils::MM_Unix - methods used by ExtUtils::MakeMaker
=head1 SYNOPSIS
C<require ExtUtils::MM_Unix;>
=head1 DESCRIPTION
The methods provided by this package are designed to be used in
conjunction with ExtUtils::MakeMaker. When MakeMaker writes a
Makefile, it creates one or more objects that inherit their methods
from a package C<MM>. MM itself doesn't provide any methods, but it
ISA ExtUtils::MM_Unix class. The inheritance tree of MM lets operating
specific packages take the responsibility for all the methods provided
by MM_Unix. We are trying to reduce the number of the necessary
overrides by defining rather primitive operations within
ExtUtils::MM_Unix.
If you are going to write a platform specific MM package, please try
to limit the necessary overrides to primitive methods, and if it is not
possible to do so, let's work out how to achieve that gain.
If you are overriding any of these methods in your Makefile.PL (in the
MY class), please report that to the makemaker mailing list. We are
trying to minimize the necessary method overrides and switch to data
driven Makefile.PLs wherever possible. In the long run less methods
will be overridable via the MY class.
=head1 METHODS
The following description of methods is still under
development. Please refer to the code for not suitably documented
sections and complain loudly to the makemaker@perl.org mailing list.
Better yet, provide a patch.
Not all of the methods below are overridable in a
Makefile.PL. Overridable methods are marked as (o). All methods are
overridable by a platform specific MM_*.pm file (See
L<ExtUtils::MM_VMS>) and L<ExtUtils::MM_OS2>).
=cut
# So we don't have to keep calling the methods over and over again,
# we have these globals to cache the values. Faster and shrtr.

I<This function is deprecated> its use is no longer necessary and is I<only

simpler mechanism and pm_to_blib() can create its own directories anyway.
Returns a Makefile entry for a .exists file in each of the @directories.
The purpose is to create a directory and provide a make target to depend on.
The make target is a .exists file in each of those directories.
For example
$mm->dir_target('$(INST_ARCHDIR)');
would return the make target C<$(INST_ARCHDIR)/.exists> which would
create $(INST_ARCHDIR) and touch .exists. You would depend on this target
to make sure $(INST_ARCHDIR) is created.
Ignores directories which have already gone through dir_target() so you
might wind up getting nothing.

You cannot build extensions below the perl source tree after executing
a 'make clean' in the perl source tree.
To rebuild extensions distributed with the perl source you should
simply Configure (to include those extensions) and then build perl as
normal. After installing perl the source tree can be deleted. It is
not needed for building extensions by running 'perl Makefile.PL'
usually without extra arguments.
It is recommended that you unpack and build additional extensions away

=item prefixify
$MM->prefixify($var, $prefix, $new_prefix, $default);
Using either $MM->{uc $var} || $Config{lc $var}, it will attempt to
replace it's $prefix with a $new_prefix.
Should the $prefix fail to match I<AND> a PREFIX was given as an
argument to WriteMakefile() it will set it to the $new_prefix +
$default. This is for systems whose file layouts don't neatly fit into
our ideas of prefixes.
This is for heuristics which attempt to create directory structures
that mirror those of the installed perl.
For example:
$MM->prefixify('installman1dir', '/usr', '/home/foo', 'man/man1');
this will attempt to remove '/usr' from the front of the
$MM->{INSTALLMAN1DIR} path (initializing it to $Config{installman1dir}
if necessary) and replace it with '/home/foo'. If this fails it will
simply use '/home/foo/man/man1'.
