Changes:
---------------------


April 06, 2008:
---------------

emerald-0.7.4 comes from source being patched with the
urefd.patch already ---> took it out.

mutual dependencies between the packages of this compiz-series 
were often stated with explicite reference to the version number
---> replaced those with the ${PV} statement.

compiz-bcop was suggested (Bug 197284) to be moved from 
x11-libs to dev-util ---> well, why not. done that!

let the dependency on libxcb of package compiz depend on 
the xcb 'USE' flag: ---> xcb? ( x11-libs/libxcb )


April 07, 2008:
---------------

added USE flags fuse and metacity to compiz-0.7.4 including the
corresponding 'use_enable' statement in 'econf'

added USE doc to compiz with correspondingly depending dodoc.


April 08, 2008:
---------------

Changed mutual dependencies of the packages and added and moved USE flags
in the family. On http://wiki.compiz-fusion.org/Installation dependencies
are listed and a canonical order of package installation is provided.

Added dependency on x11-proto/damageproto in x11-wm/compiz

Added USE flags "plugins-extra plugins-unsupported emerald"
to compiz-fusion

Moved the dependency on x11-apps/ccsm from compiz-fusion to
compiz-fusion-plugins-main in order to ensure correct installation
sequence.

Added dependency on x11-wm/compiz to dev-util/compiz-bcop in order to
ensure correct emerging sequence.

Added the new "simple-ccsm" package as x11-apps/simple-ccsm-0.7.4.
It depends on compizconfig-python and pygtk-2.0.

Compiz-fusion-plugins-mains is now equipped with USE flags
"simple-ccsm" and "ccsm" plus corresponding sensitive dependencies.
The idea is to be able to emerge simple-ccsm and/or ccsm as
configurator. In case both simple-ccsm and ccsm are not enabled per
USE flags, emerge will die! Maybe there is a better way of doing this.

Added dependency on dev-util/compiz-bcop in x11-libs/libcompizconfig.
Once again to ensure correct emerging sequence.
