30ExtUtils::MM_Unix - methods used by ExtUtils::MakeMaker
31
32=head1 SYNOPSIS
33
34C<require ExtUtils::MM_Unix;>
35
36=head1 DESCRIPTION
37
38The methods provided by this package are designed to be used in
39conjunction with ExtUtils::MakeMaker. When MakeMaker writes a
40Makefile, it creates one or more objects that inherit their methods
41from a package C<MM>. MM itself doesn't provide any methods, but it
42ISA ExtUtils::MM_Unix class. The inheritance tree of MM lets operating
43specific packages take the responsibility for all the methods provided
44by MM_Unix. We are trying to reduce the number of the necessary
45overrides by defining rather primitive operations within
46ExtUtils::MM_Unix.
47
48If you are going to write a platform specific MM package, please try
1fef88e7
JM
49to limit the necessary overrides to primitive methods, and if it is not
50possible to do so, let's work out how to achieve that gain.
1e44e2bf 51
f4ae0f5e
PP
52If you are overriding any of these methods in your Makefile.PL (in the
53MY class), please report that to the makemaker mailing list. We are
54trying to minimize the necessary method overrides and switch to data
55driven Makefile.PLs wherever possible. In the long run less methods
56will be overridable via the MY class.
57
1e44e2bf
PP
58=head1 METHODS
59
60The following description of methods is still under
61development. Please refer to the code for not suitably documented
62sections and complain loudly to the makemaker mailing list.
63
f1387719 64Not all of the methods below are overridable in a
f4ae0f5e
PP
65Makefile.PL. Overridable methods are marked as (o). All methods are
66overridable by a platform specific MM_*.pm file (See
bab2b58e 67L<ExtUtils::MM_VMS>) and L<ExtUtils::MM_OS2>).
