# Authors:	Joe Sapp <nixphoeni@gentoo.org>

#
# Usage:
# As a writer for an ebuild for gDesklets, you should set a few things:
#
#	DESKLET_NAME: The name of the desklet.
#	DOCS: Anything (like a README) that should be dodoc'd.
#	S: *Optional* The package's base directory.
#		Usually ${WORKDIR}/${DESKLET_NAME} if it was packaged
#		correctly (hence, this is the default).
# 	RDEPEND: *Optional* Set if the desklet requires a minimum version
#		of gDesklets greater than 0.34 or other packages.
