getkeys scripts question

[Jude DaShiell]

I'm spending some of my vacation time writing a debian getkeys script. 
What it does is to go out on the web and import keys so that unofficial 
debian sites with packages can have packages downloaded and have their 
contents verified later.  The marillat repository was replaced by 
debian-multimedia.org and I have the getkeys code in the script for that 
particular repository.  A question I have is what additional repositories 
do others using debian like for package downloads?  I can add their code 
to the script and then see if it will be possible to contribute to the 
speakup goodies collection.  Other distributions of Linux also have their 
own unofficial repositories where extra packages may be downloaded that 
weren't shipped with the distribution and are not available from its 
creators too.  I found an old getkeys script I had written for fedora back 
when FC3 was current on one of my disks. If there was some way using a 
shell script to get the name of the distro loaded into a variable, I might 
be able to make one getkeys script and have it work for each of the 
speakup-enabled distributions now available.  I know debian fedora and 
slackware all have unofficial packages so far.
