I'm using it partly. The draft suggests to install anything
into /usr/share/mozilla/extensions/common and then symlink to all
browsers supported in Fedora, e.g.
into /usr/share/mozilla/extensions/$browser_id/$extension_id

(But I do it manually, this seems to be a new draft, but I like the
xpi_unpack cmds etc, that could be easy integrated into the
mozilla-build package.)

The main *BIG* difference is, that draft symlinks the extension
*directory* and the script expects a install.rdf file below that.
This means, the symlinking needs to happen one step below that, so that
all files inside of the extension_id folder are symlinked, but the
install.rdf still needs to be a real copy, so it can be opened at build
time.

Rationale: A directory symlink can't be resolved at build time, so we
cannot follow that symlink on build time.

When that's changed, the scripts are working fine along each other.


About "no dependency using" from above:
	The dependencies will be added automatic with the scripts, so
	to avoid pulling in e.g. seamonkey, when you only want to have
	the firefox extension, there need to be one package for each
	extension, which owns 
	/usr/share/mozilla/extensions/$browser_id/$extension_id.

This way e.g. firefox-$extension would automaticalls require the
correct firefox versions but no seahorse, because that has to be owned
by seahorse-$extension - just as an example, but it would make sense.

Kalev, does this make sense? Can this be integrated into the drafts?
I'll try to add those macros proposed there
into /usr/lib/rpm/macros.mozilla and see if they really work out.

P.S. A working example is uploaded to fedorapeople at [1], which has
this outputs in the end with rpmbuild:  :)
