+=head1 NAME
+
+ExtUtils::MM_Any - Platform-agnostic MM methods
+
+=head1 SYNOPSIS
+
+ FOR INTERNAL USE ONLY!
+
+ package ExtUtils::MM_SomeOS;
+
+ # Temporarily, you have to subclass both. Put MM_Any first.
+ require ExtUtils::MM_Any;
+ require ExtUtils::MM_Unix;
+ @ISA = qw(ExtUtils::MM_Any ExtUtils::Unix);
+
+=head1 DESCRIPTION
+
+B<FOR INTERNAL USE ONLY!>
+
+ExtUtils::MM_Any is a superclass for the ExtUtils::MM_* set of
+modules. It contains methods which are either inherently
+cross-platform or are written in a cross-platform manner.
+
+Subclass off of ExtUtils::MM_Any I<and> ExtUtils::MM_Unix. This is a
+temporary solution.
+
+B<THIS MAY BE TEMPORARY!>
+
+
+=head1 METHODS
+
+Any methods marked I<Abstract> must be implemented by subclasses.
+
+
+=head2 Cross-platform helper methods
+
+These are methods which help writing cross-platform code.
+
+
+
+=head3 os_flavor I<Abstract>
+
+ my @os_flavor = $mm->os_flavor;
+
+@os_flavor is the style of operating system this is, usually
+corresponding to the MM_*.pm file we're using.
+
+The first element of @os_flavor is the major family (ie. Unix,
+Windows, VMS, OS/2, etc...) and the rest are sub families.
+
+Some examples:
+
+ Cygwin98 ('Unix', 'Cygwin', 'Cygwin9x')
+ Windows NT ('Win32', 'WinNT')
+ Win98 ('Win32', 'Win9x')
+ Linux ('Unix', 'Linux')
+ MacOS X ('Unix', 'Darwin', 'MacOS', 'MacOS X')
+ OS/2 ('OS/2')
+
+This is used to write code for styles of operating system.
+See os_flavor_is() for use.
+
+
+=head3 os_flavor_is
+
+ my $is_this_flavor = $mm->os_flavor_is($this_flavor);
+ my $is_this_flavor = $mm->os_flavor_is(@one_of_these_flavors);
+
+Checks to see if the current operating system is one of the given flavors.
+
+This is useful for code like:
+
+ if( $mm->os_flavor_is('Unix') ) {
+ $out = `foo 2>&1`;
+ }
+ else {
+ $out = `foo`;
+ }
+
+=cut
+
+sub os_flavor_is {
+ my $self = shift;
+ my %flavors = map { ($_ => 1) } $self->os_flavor;
+ return (grep { $flavors{$_} } @_) ? 1 : 0;
+}
+
+
+=head3 can_load_xs
+
+ my $can_load_xs = $self->can_load_xs;
+
+Returns true if we have the ability to load XS.
+
+This is important because miniperl, used to build XS modules in the
+core, can not load XS.
+
+=cut
+
+sub can_load_xs {
+ return defined &DynaLoader::boot_DynaLoader ? 1 : 0;
+}
+
+
+=head3 split_command
+
+ my @cmds = $MM->split_command($cmd, @args);
+
+Most OS have a maximum command length they can execute at once. Large
+modules can easily generate commands well past that limit. Its
+necessary to split long commands up into a series of shorter commands.
+
+C<split_command> will return a series of @cmds each processing part of
+the args. Collectively they will process all the arguments. Each
+individual line in @cmds will not be longer than the
+$self->max_exec_len being careful to take into account macro expansion.
+
+$cmd should include any switches and repeated initial arguments.
+
+If no @args are given, no @cmds will be returned.
+
+Pairs of arguments will always be preserved in a single command, this
+is a heuristic for things like pm_to_blib and pod2man which work on
+pairs of arguments. This makes things like this safe:
+
+ $self->split_command($cmd, %pod2man);
+
+
+=cut
+
+sub split_command {
+ my($self, $cmd, @args) = @_;
+
+ my @cmds = ();
+ return(@cmds) unless @args;
+
+ # If the command was given as a here-doc, there's probably a trailing
+ # newline.
+ chomp $cmd;
+
+ # set aside 30% for macro expansion.
+ my $len_left = int($self->max_exec_len * 0.70);
+ $len_left -= length $self->_expand_macros($cmd);
+
+ do {
+ my $arg_str = '';
+ my @next_args;
+ while( @next_args = splice(@args, 0, 2) ) {
+ # Two at a time to preserve pairs.
+ my $next_arg_str = "\t ". join ' ', @next_args, "\n";
+
+ if( !length $arg_str ) {
+ $arg_str .= $next_arg_str
+ }
+ elsif( length($arg_str) + length($next_arg_str) > $len_left ) {
+ unshift @args, @next_args;
+ last;
+ }
+ else {
+ $arg_str .= $next_arg_str;
+ }
+ }
+ chop $arg_str;
+
+ push @cmds, $self->escape_newlines("$cmd \n$arg_str");
+ } while @args;
+
+ return @cmds;
+}
+
+
+sub _expand_macros {
+ my($self, $cmd) = @_;
+
+ $cmd =~ s{\$\((\w+)\)}{
+ defined $self->{$1} ? $self->{$1} : "\$($1)"
+ }e;
+ return $cmd;
+}
+
+
+=head3 echo
+
+ my @commands = $MM->echo($text);
+ my @commands = $MM->echo($text, $file);
+ my @commands = $MM->echo($text, $file, $appending);
+
+Generates a set of @commands which print the $text to a $file.
+
+If $file is not given, output goes to STDOUT.
+
+If $appending is true the $file will be appended to rather than
+overwritten.
+
+=cut
+
+sub echo {
+ my($self, $text, $file, $appending) = @_;
+ $appending ||= 0;
+
+ my @cmds = map { '$(NOECHO) $(ECHO) '.$self->quote_literal($_) }
+ split /\n/, $text;
+ if( $file ) {
+ my $redirect = $appending ? '>>' : '>';
+ $cmds[0] .= " $redirect $file";
+ $_ .= " >> $file" foreach @cmds[1..$#cmds];
+ }
+
+ return @cmds;
+}
+
+
+=head3 wraplist
+
+ my $args = $mm->wraplist(@list);
+
+Takes an array of items and turns them into a well-formatted list of
+arguments. In most cases this is simply something like:
+
+ FOO \
+ BAR \
+ BAZ
+
+=cut
+
+sub wraplist {
+ my $self = shift;
+ return join " \\\n\t", @_;
+}
+
+
+=head3 maketext_filter
+
+ my $filter_make_text = $mm->maketext_filter($make_text);
+
+The text of the Makefile is run through this method before writing to
+disk. It allows systems a chance to make portability fixes to the
+Makefile.
+
+By default it does nothing.
+
+This method is protected and not intended to be called outside of
+MakeMaker.
+
+=cut
+
+sub maketext_filter { return $_[1] }
+
+
+=head3 cd I<Abstract>
+
+ my $subdir_cmd = $MM->cd($subdir, @cmds);
+
+This will generate a make fragment which runs the @cmds in the given
+$dir. The rough equivalent to this, except cross platform.
+
+ cd $subdir && $cmd
+
+Currently $dir can only go down one level. "foo" is fine. "foo/bar" is
+not. "../foo" is right out.
+
+The resulting $subdir_cmd has no leading tab nor trailing newline. This
+makes it easier to embed in a make string. For example.
+
+ my $make = sprintf <<'CODE', $subdir_cmd;
+ foo :
+ $(ECHO) what
+ %s
+ $(ECHO) mouche
+ CODE
+
+
+=head3 oneliner I<Abstract>
+
+ my $oneliner = $MM->oneliner($perl_code);
+ my $oneliner = $MM->oneliner($perl_code, \@switches);
+
+This will generate a perl one-liner safe for the particular platform
+you're on based on the given $perl_code and @switches (a -e is
+assumed) suitable for using in a make target. It will use the proper
+shell quoting and escapes.
+
+$(PERLRUN) will be used as perl.
+
+Any newlines in $perl_code will be escaped. Leading and trailing
+newlines will be stripped. Makes this idiom much easier:
+
+ my $code = $MM->oneliner(<<'CODE', [...switches...]);
+some code here
+another line here
+CODE
+
+Usage might be something like:
+
+ # an echo emulation
+ $oneliner = $MM->oneliner('print "Foo\n"');
+ $make = '$oneliner > somefile';
+
+All dollar signs must be doubled in the $perl_code if you expect them
+to be interpreted normally, otherwise it will be considered a make
+macro. Also remember to quote make macros else it might be used as a
+bareword. For example:
+
+ # Assign the value of the $(VERSION_FROM) make macro to $vf.
+ $oneliner = $MM->oneliner('$$vf = "$(VERSION_FROM)"');
+
+Its currently very simple and may be expanded sometime in the figure
+to include more flexible code and switches.
+
+
+=head3 quote_literal I<Abstract>
+
+ my $safe_text = $MM->quote_literal($text);
+
+This will quote $text so it is interpreted literally in the shell.
+
+For example, on Unix this would escape any single-quotes in $text and
+put single-quotes around the whole thing.
+
+
+=head3 escape_newlines I<Abstract>
+
+ my $escaped_text = $MM->escape_newlines($text);
+
+Shell escapes newlines in $text.
+
+
+=head3 max_exec_len I<Abstract>
+
+ my $max_exec_len = $MM->max_exec_len;
+
+Calculates the maximum command size the OS can exec. Effectively,
+this is the max size of a shell command line.
+
+=for _private
+$self->{_MAX_EXEC_LEN} is set by this method, but only for testing purposes.
+
+
+=head3 make
+
+ my $make = $MM->make;
+
+Returns the make variant we're generating the Makefile for. This attempts
+to do some normalization on the information from %Config or the user.
+
+=cut
+
+sub make {
+ my $self = shift;
+
+ my $make = lc $self->{MAKE};
+
+ # Truncate anything like foomake6 to just foomake.
+ $make =~ s/^(\w+make).*/$1/;
+
+ # Turn gnumake into gmake.
+ $make =~ s/^gnu/g/;
+
+ return $make;
+}
+
+
+=head2 Targets

+These are methods which produce make targets.
+
+
+=head3 all_target
+

+in blib/.
