# bsd.perl.mk - Support for Perl-based ports.
#
# Created by: Gabor Kovesdan <gabor@FreeBSD.org>
#
# For FreeBSD committers:
# Please send all suggested changes to the maintainer instead of committing
# them to CVS yourself.
#
# PERL5			- Set to full path of perl5, either in the system or
#				  installed from a port.
# PERL			- Set to full path of perl5, either in the system or
#				  installed from a port, but without the version number.
#				  Use this if you need to replace "#!" lines in scripts.
# PERL_VERSION	- Full version of perl5 (see below for current value).
# PERL_LEVEL	- Perl version as an integer of the form MNNNPP, where
#				  M is major version, N is minor version, and P is
#				  the patch level. E.g., PERL_VERSION=5.8.1 would give
#				  a PERL_LEVEL of 500801. This can be used in comparisons
#				  to determine if the version of perl is high enough,
#				  whether a particular dependency is needed, etc.
# PERL_ARCH		- Directory name of architecture dependent libraries
#				  (value: mach).
# PERL_PORT		- Name of the perl port that is installed
#				  (value: perl5.8)
# SITE_PERL		- Directory name where site specific perl packages go.
#				  This value is added to PLIST_SUB.
# USE_PERL5		- If your port needs a specific version of Perl, you
#				  can easily specify that with this knob.  If
#				  you need a certain minimal version, but don't
#				  care if about the upperversion, just put the
#				  + sign behind the version.  If you want to
#				  specify a latest version your port can be used
#				  with, suffix the version number with a - sign.
#				  Exact version can also be specified if you just
#				  set USE_PERL5 to the desired version.  If you
#				  just set USE_PERL5 to "yes", Perl will be
#				  pulled in as a dependency but no version check
#				  is done.
# USE_PERL5_REASON
#				- Along with USE_PERL5, you can set a specific reason,
#				  why a given version is required.
#
# Examples:
# 	USE_PERL5=	yes	# port requires any version of Perl5 to build.
# 	USE_PERL5=	5.8.0+	# port requires at least Perl 5.8.0 to build.
#	USE_PERL5=	5.8.2	# port is only usable with Perl 5.8.2.
#	USE_PERL5=	5.8.6-	# port is only usbale with Perl 5.8.6 or prior.
#
# This line along with a properly set USE_PERL5 will give the user a reason,
# why the specific ports cannot be installed into the given environment.
#
#	USE_PERL5_REASON=	this module is already part of your Perl version
#
# PERL_CONFIGURE
#				- Configure using Perl's MakeMaker.  Implies USE_PERL5.
#				  The version requirement can be specified here,
#				  as well.
# USE_PERL5_BUILD
#				- If set, this port uses perl5 in one or more of the
#				  extract, patch, build or install phases.
#				  The version requirement can be specified here,
#				  as well.
# USE_PERL5_RUN	- If set, this port uses perl5 for running.  The
#			 	  version requirement can be specified here,
#				  as well.
# PERL_MODBUILD	- Use Module::Build to configure, build and install
#				  port.  The version requirement can be specified
#				  here, as well.
#
# WANT_PERL		- Set this if your port conditionally depends on Perl.
#				  This MUST appear before the inclusion of bsd.port.pre.mk.
