12 | |
13 | Module::Build::Platform::VMS - Builder class for VMS platforms |
14 | |
15 | =head1 DESCRIPTION |
16 | |
17 | This module inherits from C<Module::Build::Base> and alters a few |
18 | minor details of its functionality. Please see L<Module::Build> for |
19 | the general docs. |

25 | =item new |
26 | |
27 | Change $self->{build_script} to 'Build.com' so @Build works. |

41 | =item cull_args |
42 | |
43 | '@Build foo' on VMS will not preserve the case of 'foo'. Rather than forcing |
44 | people to write '@Build "foo"' we'll dispatch case-insensitively. |
