- =head1 NAME
-
- ExtUtils::MM_VMS - methods to override UN*X behaviour in ExtUtils::MakeMaker
-
- =head1 SYNOPSIS
-
- Do not use this directly.
- Instead, use ExtUtils::MM and it will figure out which MM_*
- class to use for you.
-
- =head1 DESCRIPTION
-
- See ExtUtils::MM_Unix for a documentation of the methods provided
- there. This package overrides the implementation of these methods, not
- the semantics.

- =item wraplist
-
- Converts a list into a string wrapped at approximately 80 columns.

- # This isn't really an override. It's just here because ExtUtils::MM_VMS
- # appears in @MM::ISA before ExtUtils::Liblist::Kid, so if there isn't an ext()
- # in MM_VMS, then AUTOLOAD is called, and bad things happen. So, we just
- # mimic inheritance here and hand off to ExtUtils::Liblist::Kid.
- # XXX This hackery will die soon. --Schwern

- =head2 Methods
-
- Those methods which override default MM_Unix methods are marked
- "(override)", while methods unique to MM_VMS are marked "(specific)".
- For overridden methods, documentation is limited to an explanation
- of why this method overrides the MM_Unix method; see the ExtUtils::MM_Unix
- documentation for more details.

- =item guess_name (override)
-
- Try to determine name of extension being built. We begin with the name
- of the current directory. Since VMS filenames are case-insensitive,
- however, we look for a F<.pm> file whose name matches that of the current
- directory (presumably the 'main' F<.pm> file for this extension), and try
- to find a C<package> statement from which to obtain the Mixed::Case
- package name.

- # extension into a working directory whose name doesn't reflect the
- # extension's name. We'll use the name of a unique .pm file, or the
- # first .pm file with a matching .xs file.

-
- =item maybe_command (override)
-
- Follows VMS naming conventions for executable files.
- If the name passed in doesn't exactly match an executable file,
- appends F<.Exe> (or equivalent) to check for executable image, and F<.Com>
- to check for DCL procedure. If this fails, checks directories in DCL$PATH
- and finally F<Sys$System:> for an executable file having the name specified,
- with or without the F<.Exe>-equivalent suffix.

- }
-
-
- =item pasthru (override)
-
- VMS has $(MMSQUALIFIERS) which is a listing of all the original command line
- options. This is used in every invokation of make in the VMS Makefile so
- PASTHRU should not be necessary. Using PASTHRU tends to blow commands past
- the 256 character limit.

-
-
- =item pm_to_blib (override)
-
- VMS wants a dot in every file so we can't have one called 'pm_to_blib',
- it becomes 'pm_to_blib.' and MMS/K isn't smart enough to know that when
- you have a target called 'pm_to_blib' it should look for 'pm_to_blib.'.
-
- So in VMS its pm_to_blib.ts.

- $(NOECHO) $(NOOP)
-
- MAKE
-
- return $make;
- }
-
-
- =item perl_script (override)
-
- If name passed in doesn't specify a readable file, appends F<.com> or
- F<.pl> and tries again, since it's customary to have file types on all files
- under VMS.
-
- =cut
-
- sub perl_script {
- my($self,$file) = @_;

-
- (override) Because of the difficulty concatenating VMS filepaths we
- must pre-expand the DEST* variables.

-
- =item init_others (override)
-
- Provide VMS-specific forms of various utility commands, then hand
- off to the default MM_Unix method.
-
- DEV_NULL should probably be overriden with something.
-
- Also changes EQUALIZE_TIMESTAMP to set revision date of target file to
- one second later than source file, since MMK interprets precisely
- equal revision dates for a source and target file as a sign that the

- extension into the Perl image, so this isn't the normal build path.
- Consequently, it hasn't really been tested, and may well be incomplete.
