Re[1]: [Suggestion] New function `emacs-version>=' (Wedler, Christoph)

["Eric M. Ludlam" <eric@siege-engine.com>]

I apologize for the non-existent CC list, I'm responding to a digest.
I also apologize for not reading all the messages associated with this
thread first on the off chance I am repeating something.

I develop and maintain several Emacs Lisp tools in my imaginary spare
time which I keep in my CEDET project.

http://cedet.sourceforge.net/

and have had versioning trouble between my own packages, and with
other not-in-emacs packages.  To help confine version problems, I
wrote (and posted to gnu.emacs.sources) a little tool I called
"inversion" to help identify if what you need is "in version"
whatever of some package.

You can peek at it in CVS here.

http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/cedet/cedet/common/

or

http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/*checkout*/cedet/cedet/common/inversion.el?rev=HEAD&content-type=text/plain

Perhaps it would be useful.
