53 | =head1 NAME | |
54 | ||
55 | ExtUtils::MM_Unix - methods used by ExtUtils::MakeMaker | |
56 | ||
57 | =head1 SYNOPSIS | |
58 | ||
59 | C<require ExtUtils::MM_Unix;> | |
60 | ||
61 | =head1 DESCRIPTION | |
62 | ||
63 | The methods provided by this package are designed to be used in | |
64 | conjunction with ExtUtils::MakeMaker. When MakeMaker writes a | |
65 | Makefile, it creates one or more objects that inherit their methods | |
66 | from a package C<MM>. MM itself doesn't provide any methods, but it | |
67 | ISA ExtUtils::MM_Unix class. The inheritance tree of MM lets operating | |
68 | specific packages take the responsibility for all the methods provided | |
69 | by MM_Unix. We are trying to reduce the number of the necessary | |
70 | overrides by defining rather primitive operations within | |
71 | ExtUtils::MM_Unix. | |
72 | ||
73 | If you are going to write a platform specific MM package, please try | |
74 | to limit the necessary overrides to primitive methods, and if it is not | |
75 | possible to do so, let's work out how to achieve that gain. | |
76 | ||
77 | If you are overriding any of these methods in your Makefile.PL (in the | |
78 | MY class), please report that to the makemaker mailing list. We are | |
79 | trying to minimize the necessary method overrides and switch to data | |
80 | driven Makefile.PLs wherever possible. In the long run less methods | |
81 | will be overridable via the MY class. | |
82 | ||
83 | =head1 METHODS | |
84 | ||
85 | The following description of methods is still under | |
86 | development. Please refer to the code for not suitably documented | |
87 | sections and complain loudly to the makemaker@perl.org mailing list. | |
88 | Better yet, provide a patch. | |
89 | ||
90 | Not all of the methods below are overridable in a | |
91 | Makefile.PL. Overridable methods are marked as (o). All methods are | |
92 | overridable by a platform specific MM_*.pm file. | |
93 | ||
94 | Cross-platform methods are being moved into MM_Any. If you can't find | |
95 | something that used to be in here, look in MM_Any. | |
96 | ||

99 | # So we don't have to keep calling the methods over and over again, | |
100 | # we have these globals to cache the values. Faster and shrtr. | |
