Hi all,

I've been wanting to make some changes to this eclass for a while since I've
been putting on some bandages to make things work.  This is a rather major
overhaul.  Basically packaging upstream got a lot more regulated since obz and
I wrote the original eclass [1], so we can simplify many things.  This results
in trivial ebuilds, ease of maintaining, quicker installs, and (I think) a
better user interface.

Anyways, a diff would be useless so I've attached the proposed eclass [2].

My plan for updating the tree is as follows:
 1) Wait until at least 25 January 2010, discussing on the gentoo-dev ml
 2) As long as there are no pending items for review, I will test with all
current x11-plugins/desklet-* ebuilds, diffing the "old" and "new" directories
 3) Commit the new eclass
 4) Tweak the x11-plugins/desklet-* ebuilds to remove unneeded variables

Please let me know what you think.

Thanks,
Joe

# @BLURB: Installation functions for Desklets and Controls supported
# by gDesklets
# @DESCRIPTION:
# The gdesklets eclass provides a simple way to create ebuilds for
# globally installing desktop applets ("Desklets") and supporting code
# ("Controls") used in the gDesklets framework (provided by
# gnome-extra/gdesklets-core)
#
# This eclass assumes a package following the instructions at
# http://gdesklets.de/index.php?q=node/2 .  Specifically, the package
# should be a Desklet or Control ONLY (and *not* a Sensor).  You
# technically could have an ebuild that works around this limitation,
# but no new packages should be added to the tree that do this (mainly
# for ease of maintenance).
#
# Original authors:	Joe Sapp <nixphoeni@gentoo.org>
#			Mike Gardiner <obz@gentoo.org>

# @ECLASS_VARIABLE: DESKLET_NAME
# @DESCRIPTION:
# *Optional*  The name of the Desklet, if the package is one. The
# default is to assume a Desklet with the name being ${PN} without the
# "desklet-" prefix.

# @ECLASS_VARIABLE: CONTROL_NAME
# @DESCRIPTION:
# *Optional*  The name of the Control, if the package is one.

# @ECLASS_VARIABLE: DOCS
# @DESCRIPTION:
# Anything (like a README) that should be dodoc'd.

# @ECLASS_VARIABLE: SLOT
# @DESCRIPTION:
# Set only if the package is a Control and it provides a different
# interface (i.e. expands to a different install directory) than a
# previous version.
