7 | ||
8 | ExtUtils::MM_Win32 - methods to override UN*X behaviour in ExtUtils::MakeMaker | |
9 | ||
10 | =head1 SYNOPSIS | |
11 | ||
12 | use ExtUtils::MM_Win32; # Done internally by ExtUtils::MakeMaker if needed | |
13 | ||
14 | =head1 DESCRIPTION | |
15 | ||
16 | See ExtUtils::MM_Unix for a documentation of the methods provided | |
17 | there. This package overrides the implementation of these methods, not | |
18 | the semantics. | |
