# This script acts as a simple interface for building extensions.
# It's actually a cut and shut of the Unix version ext/utils/makeext and the
# Windows version win32/build_ext.pl hence the two invocation styles.
# On Unix, it primarily used by the perl Makefile one extension at a time:
#
# d_dummy $(dynamic_ext): miniperl preplibrary FORCE
# @$(RUN) ./miniperl make_ext.pl --target=dynamic $@ MAKE=$(MAKE) LIBPERL_A=$(LIBPERL)
#
# On Windows or VMS,
# If '--static' is specified, static extensions will be built.
# If '--dynamic' is specified, dynamic extensions will be built.
# If '--nonxs' is specified, nonxs extensions will be built.
# If '--dynaloader' is specified, DynaLoader will be built.
# If '--all' is specified, all extensions will be built.
#
# make_ext.pl "MAKE=make [-make_opts]" --dir=directory [--target=target] [--static|--dynamic|--all] +ext2 !ext1
#
# E.g.
#
# make_ext.pl "MAKE=nmake -nologo" --dir=..\ext
#
# make_ext.pl "MAKE=nmake -nologo" --dir=..\ext --target=clean
#
# make_ext.pl MAKE=dmake --dir=..\ext
#
# make_ext.pl MAKE=dmake --dir=..\ext --target=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 aren't countermanded
# by an '!ext' and are appropriate to the type of building being done.
# An extensions follows the format of Foo/Bar, which would be extension Foo::Bar
# It may be deleted in a later release of perl so try to
# avoid using it for other purposes.
