Re: First pass at script to build start menu icons

[Harold L Hunt II <huntharo at msu dot edu>]

Brian,

That script looks great to me.

I would like some input on a few things before I go ahead with this 
(unless no one responds, in which case I will just go ahead):

The list of programs to create icons for is embedded in the script 
itself.  The script will still work, since I just copy the whole thing 
to /etc/postinstall/XWin-bin-icons.sh.  However, I was thinking about 
how we should probably install this script in /usr/X11R6/bin and the 
list of icons in some other location.  That way a user could manually 
run or rerun the script to replace icons that they had removed 
accidentally.  Furthermore, having the list of icons in a plain text 
file would allow the creation of a preremove script that (is this 
possible?) did a diff between the old icon list and the new icon list to 
find out which icons were being specifically removed between versions.

Alternatively, we could make the preremove script remove the entire list 
of icons that were created the first time, then have the upgraded 
postinstall script just put them all back.  In any case it would be 
smart to have that list of icons in a shared location so that the 
postinstall and preremove scripts could both reference it.

Thanks for contributing Brian, I really appreciate it.
