=head1 NAME
buildext.pl - build extensions
=head1 SYNOPSIS
buildext.pl make [-make_opts] dep directory [target] [--static|--dynamic] +ext2 !ext1
E.g.
buildext.pl nmake -nologo perldll.def ..\ext
buildext.pl nmake -nologo perldll.def ..\ext clean
buildext.pl dmake perldll.def ..\ext
buildext.pl dmake perldll.def ..\ext clean
Will skip building extensions which are marked with an '!' char.
Mostly because they still not ported to specified platform.
If any extensions are listed with a '+' char then only those
extensions will be built, but only if they arent countermanded
by an '!ext' and are appropriate to the type of building being done.
If '--static' specified, only static extensions will be built.
If '--dynamic' specified, only dynamic extensions will be built.
--create-perllibst-h
creates perllibst.h file for inclusion from perllib.c
--list-static-libs:
prints libraries for static linking and exits
