+# Supported Variables and their behaviors:
+#
+# GMAKE		- Set to path of GNU make if not in $PATH.
+# DISTDIR 	- Where to get gzip'd, tarballed copies of original sources.
+# DISTNAME	- Name of package or distribution.
+# WRKDIR 	- A temporary working directory that gets *clobbered* on clean.
+# WRKSRC	- A subdirectory of ${WRKDIR} where the distribution actually
+#		  unpacks to.  Defaults to ${WRKDIR}/${DISTNAME}.
+# PATCHDIR 	- A directory containing required patches.
+# SCRIPTDIR 	- A directory containing auxilliary scripts.
+# FILESDIR 	- A directory containing any miscellaneous additional files.
+# PKGDIR 	- Package creation files.
+#
+# USE_GMAKE	- Says that the package uses gmake (*).
+# GNU_CONFIGURE	- Says that the package uses GNU configure (*).
+# GNU_CONFIGURE_ARGS - If defined, override defaults with these args (*).
+# HOME_LOCATION	- site/path name (or user's email address) describing
+#		  where this package came from or can be obtained if the
+#		  tarball is missing.
+# 
+#
+# Default targets and their behaviors:
+#
+# extract	- Unpacks ${DISTDIR}/${DISTNAME}.tar.gz into ${WRKDIR}.
+# configure	- Applys patches, if any, and runs either GNU configure, a
+#		  local configure or nothing, depending on settings.
+# build		- Actually compile the sources.
+# install	- Install the results of a build.
+# package	- Create a package from a build.
