# Some, but not all of variables are required. The following list
# describes the required variables:
#
# * URL:	The main website of the upstream project
# * REPO:	The location of the package on the source pacakge
#		server. This might be one of core, main, dev, or
#		perhaps others.
# * BRIEF:	Short description, should be 50 chars or less
# * SNAPVER:	This is the package version. When a package is
#		changed, but no changes are made to the source code
#		this value should be increased. This would include
#		things like usher being modified, changes to default
#		configuration files, file permissions, etc.
# * ARCHIVE:	The default commands that set this variable should
#		work in most cases, but in some cases it may need
#		to be modified. This variable should contain the
#		path to the source of the package (./SRC/filename)
# * TYPE:	This is probably not really needed due to the
#		ability	of gnu tar to figure it out on its own.
#		Should probably be removed at some point.
# * SRCDIR:	This is the name of the source directory after the
#		package source is extracted. The default command
#		should in most cases set this automatically.
# * PATCHDIR:	This directory should be ./SRC/patches and is
#		required, whether or not patches are used.
# * VERSION:	This should be set automatically based on the
#		version string in the source directory and SNAPVER.
#		The default command here should work in many cases,
#		but certain packages may need to use a different
#		method.
#
# Variables that aren't required:
#
# * ARCH:	This should be populated for packages which contain
#		compiled binaries. If it is not populated the ARCH
#		will be set to 'noarch'.
# * DEPENDS:	If any other packages are required for this package
#		to function then they need to be listed here,
#		preferably in alphabetical order.
# * BUILDDEPS:	Any package beyond packages from the core repo
#		need to be listed here. The idea is that we
#		can automate building and testing packages
#		from clean core systems. The core repo is
#		intended to include only the base minimum
#		packages which provide a functional system.
# * SRCPKG:	By default this is populated automatically with
#		the name of the package (current directory). If
#		the source package is used to generate multiple
#		packages then this variable should contain the
#		name of the git repo that tracks the source.
# * DESC:	This is to be used to provide a longer description
#		of the package.
