Add MimeType too!
However, I was thinking on something easier. Just storing the .desktop
file in the files dir and processing/installing it automatically as done
with the rc.d scripts. This'd have the advantage of being able to add
new lines at will to specific packages (say localized comments, which
may be good).

Cool :) Didn't know these tools, but as they already exist... it's
another point in favor of this approach.

I think it'd be easier to simply have a wm.d directory where each wm
could place its generation file. Then, at install time, run all the
scripts found in that directory.
SYSCONFDIR/wm.d exclusively seems incorrect to me though. We should
first look there, but then fall back to a directory under PREFIX, say
PREFIX/share/wm.d. How? First construct a list of wms based on all
the files available under the prefix directory. Then, for each item,
see if there is one with the same name in the sysconfdir. If found,
run it; otherwise, run the one in prefix.
This can be easily done from an INSTALL script, shared by all
packages that provide .desktop files. Then you'd have transparent
handling of all the wms.
(Of course, the installation of a specific wm should also trigger
the execution of the files.)

/usr/pkg/share/gnome/apps is deprecated. All the stuff now goes into
share/applications (referred by XDG_DATA_DIRS ) and each file
classifies itself by its Categories entry.
Dunno what KDE will do, but using a single directory seems simpler,
easier to parse and to manage. But as long as the files have the
Categories property, it doesn't really matter where they are; you
can read them from many places and merge them in the same menu.
 Please, don't get me started on the XDG spec...
