See ExtUtils::MM_Unix for a documentation of the methods
provided there. This package overrides the implementation
of these methods, not the semantics.

eliminate_macros
Expands MM[KS]/Make macros in a text string, using
the contents of identically named elements of %$self,
and returns the result as a file specification in
Unix syntax.
fixpath
Catchall routine to clean up problem MM[SK]/Make
macros. Expands macros in any directory
specification, in order to avoid juxtaposing two
VMS-syntax directories when MM[SK] is run. Also
expands expressions which are all macro, so that we
can tell how long the expansion is, and avoid
overrunning DCL's command buffer when MM[KS] is
running.
If optional second argument has a TRUE value, then
the return string is a VMS-syntax directory
specification, otherwise it is a VMS-syntax file
specification.
catdir
Concatenates a list of file specifications, and
returns the result as a VMS-syntax directory
specification.
catfile
Concatenates a list of file specifications, and
returns the result as a VMS-syntax directory
specification.
wraplist
Converts a list into a string wrapped at
approximately 80 columns.
curdir (override)
Returns a string representing of the current
directory.
rootdir (override)
Returns a string representing of the root directory.
updir (override)
Returns a string representing of the parent
directory.

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.
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 .pm file whose name matches that of the current
directory (presumably the 'main' .pm file for this
extension), and try to find a package statement from
which to obtain the Mixed::Case package name.
find_perl (override)
Use VMS file specification syntax and CLI commands to
find and invoke Perl images.
path (override)
Translate logical name DCL$PATH as a searchlist,
rather than trying to split string value of
$ENV{'PATH'}.
maybe_command (override)
Follows VMS naming conventions for executable files.
If the name passed in doesn't exactly match an
executable file, appends .Exe (or equivalent) to
check for executable image, and .Com to check for DCL
procedure. If this fails, checks directories in
DCL$PATH and finally Sys$System: for an executable
file having the name specified, with or without the
.Exe-equivalent suffix.
maybe_command_in_dirs (override)
Uses DCL argument quoting on test command line.
perl_script (override)
If name passed in doesn't specify a readable file,
appends .com or .pl and tries again, since it's
customary to have file types on all files under VMS.
file_name_is_absolute (override)
Checks for VMS directory spec as well as Unix
separators.
replace_manpage_separator
Use as separator a character which is legal in a
VMS-syntax file name.
init_others (override)
Provide VMS-specific forms of various utility
commands, then hand off to the default MM_Unix
method.
constants (override)
Fixes up numerous file and directory macros to insure
VMS syntax regardless of input syntax. Also adds a
few VMS-specific macros and makes lists of files
comma-separated.
cflags (override)
Bypass shell script and produce qualifiers for CC
directly (but warn user if a shell script for this
extension exists). Fold multiple /Defines into one,
since some C compilers pay attention to only one
instance of this qualifier on the command line.
const_cccmd (override)
Adds directives to point C preprocessor to the right
place when handling #include <sys/foo.h> directives.
Also constructs CC command line a bit differently
than MM_Unix method.
pm_to_blib (override)
DCL still accepts a maximum of 255 characters on a
command line, so we write the (potentially) long list
of file names to a temp file, then persuade Perl to
read it instead of the command line to find args.
tool_autosplit (override)
Use VMS-style quoting on command line.
tool_sxubpp (override)
Use VMS-style quoting on xsubpp command line.
xsubpp_version (override)
Test xsubpp exit status according to VMS rules ($sts
& 1 ==> good) rather than Unix rules ($sts == 0 ==>
good).
tools_other (override)
Adds a few MM[SK] macros, and shortens some the
installatin commands, in order to stay under DCL's
255-character limit. 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 target needs to be
updated.
dist (override)
Provide VMSish defaults for some values, then hand
off to default MM_Unix method.
c_o (override)
Use VMS syntax on command line. In particular,
$(DEFINE) and $(PERL_INC) have been pulled into
$(CCCMD). Also use MM[SK] macros.
xs_c (override)
Use MM[SK] macros.
xs_o (override)
Use MM[SK] macros, and VMS command line for C
compiler.
top_targets (override)
Use VMS quoting on command line for Version_check.
dlsyms (override)
Create VMS linker options files specifying universal
symbols for this extension's shareable image, and
listing other shareable images or libraries to which
it should be linked.
dynamic_lib (override)
Use VMS Link command.
dynamic_bs (override)
Use VMS-style quoting on Mkbootstrap command line.
static_lib (override)
Use VMS commands to manipulate object library.
manifypods (override)
Use VMS-style quoting on command line, and VMS
logical name to specify fallback location at build
time if we can't find pod2man.
processPL (override)
Use VMS-style quoting on command line.
installbin (override)
Stay under DCL's 255 character command line limit
once again by splitting potentially long list of
files across multiple lines in realclean target.
subdir_x (override)
Use VMS commands to change default directory.
clean (override)
Split potentially long list of files across multiple
commands (in order to stay under the magic command
line limit). Also use MM[SK] commands for handling
subdirectories.
realclean (override)
Guess what we're working around? Also, use MM[SK]
for subdirectories.
dist_basics (override)
Use VMS-style quoting on command line.
dist_core (override)
Syntax for invoking VMS_Share differs from that for
Unix shar, so shdist target actions are VMS-specific.
dist_dir (override)
Use VMS-style quoting on command line.
dist_test (override)
Use VMS commands to change default directory, and use
VMS-style quoting on command line.
install (override)
Work around DCL's 255 character limit several
times,and use VMS-style command line quoting in a few
cases.
perldepend (override)
Use VMS-style syntax for files; it's cheaper to just
do it directly here than to have the MM_Unix method
call catfile repeatedly. Also use config.vms as
source of original config data if the Perl
distribution is available; config.sh is an ancillary
file under VMS. Finally, if we have to rebuild
Config.pm, use MM[SK] to do it.
makefile (override)
Use VMS commands and quoting.
test (override)
Use VMS commands for handling subdirectories.
test_via_harness (override)
Use VMS-style quoting on command line.
test_via_script (override)
Use VMS-style quoting on command line.
makeaperl (override)
Undertake to build a new set of Perl images using VMS
commands. Since VMS does dynamic loading, it's not
necessary to statically link each 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.
nicetext (override)
Insure that colons marking targets are preceded by
space, in order to distinguish the target delimiter
from a colon appearing as part of a filespec.
