# Supported Variables and their behaviors:
#
# Variables that typically apply to all ports:
# 
# PORTSDIR		- The root of the ports tree (default: /usr/ports).
# DISTDIR 		- Where to get gzip'd, tarballed copies of original sources
#				  (default: ${PORTSDIR}/distfiles).
# PREFIX		- Where to install things in general (default: /usr/local).
# MASTER_SITES	- Primary location(s) for distribution files if not found
#				  locally.
# MASTER_SITE_OVERRIDE - If set, override the MASTER_SITES setting with this
#				  value.
# MASTER_SITE_FREEBSD - If set, only use the FreeBSD master repository for
#				  MASTER_SITES.
# PACKAGES		- A top level directory where all packages go (rather than
#				  going locally to each port). (default: ${PORTSDIR}/packages).
# GMAKE			- Set to path of GNU make if not in $PATH (default: gmake).
# XMKMF			- Set to path of `xmkmf' if not in $PATH (default: xmkmf).
#
# Variables that typically apply to an individual port:
#
# WRKDIR 		- A temporary working directory that gets *clobbered* on clean.
# WRKSRC		- A subdirectory of ${WRKDIR} where the distribution actually
#				  unpacks to.  (Default: ${WRKDIR}/${DISTNAME} unless
#				  NO_WRKSUBDIR is set, in which case simply ${WRKDIR}).
# DISTNAME		- Name of port or distribution.
# DISTFILES		- Name(s) of archive file(s) containing distribution
#				  (default: ${DISTDIR}/${DISTNAME}${EXTRACT_SUFX}).
# EXTRACT_ONLY		- If defined, a subset of ${DISTFILES} you want to
#			  	actually extract.
# PATCHDIR 		- A directory containing any required patches.
# SCRIPTDIR 	- A directory containing any auxilliary scripts.
# FILESDIR 		- A directory containing any miscellaneous additional files.
# PKGDIR 		- A direction containing any package creation files.
#
# NO_EXTRACT	- Use a dummy (do-nothing) extract target.
# NO_CONFIGURE	- Use a dummy (do-nothing) configure target.
# NO_BUILD		- Use a dummy (do-nothing) build target.
# NO_PACKAGE	- Use a dummy (do-nothing) package target.
# NO_INSTALL	- Use a dummy (do-nothing) install target.
# NO_WRKSUBDIR	- Assume port unpacks directly into ${WRKDIR}.
# NO_WRKDIR		- There's no work directory at all; port does this someplace
#				  else.
# NO_DEPENDS	- Don't verify build of dependencies.
# USE_GMAKE		- Says that the port uses gmake.
# USE_IMAKE		- Says that the port uses imake.
# HAS_CONFIGURE	- Says that the port has its own configure script.
# GNU_CONFIGURE	- Set if you are using GNU configure (optional).
# CONFIGURE_ARGS - Pass these args to configure, if $HAS_CONFIGURE.
# IS_INTERACTIVE - Set this if your port needs to interact with the user
#				during a build.  User can then decide to skip this port by
#				setting BATCH, or compile ONLY interactive ports by setting
#				INTERACTIVE.
# DEPENDS		- A list of other ports this package depends on being
#				  made first, relative to ${PORTSDIR} (e.g. x11/tk, lang/tcl,
#				  etc).
# EXTRACT_CMD	- Command for extracting archive (default: tar).
# EXTRACT_SUFX	- Suffix for archive names (default: .tar.gz).
# EXTRACT_ARGS	- Arguments to ${EXTRACT_CMD} (default: -C ${WRKDIR} -xzf).
#
# NCFTP			- Full path to ncftp command if not in $PATH (default: ncftp).
# NCFTP_ARGS	- Arguments to ${NCFTP} (default: -N).
#
#
# Default targets and their behaviors:
#
# fetch			- Retrieves ${DISTFILES} into ${DISTDIR} as necessary.
# extract		- Unpacks ${DISTFILES} into ${WRKDIR}.
# configure		- Applies patches, if any, and runs either GNU configure, one
#				  or more local configure scripts or nothing, depending on
#				  what's available.
# patch			- Apply any provided patches to the source.
# build			- Actually compile the sources.
# install		- Install the results of a build.
# reinstall		- Install the results of a build, ignoring "already installed"
#				  flag.
# package		- Create a package from a build.
#
# Default sequence for "all" is:  fetch extract configure build
