[imp] What's the advantage of using CVS?

It also lets you use some of the less developed modules that don't work 
with the released versions.

There's a lot of info about how to get CVS files, and use CVS to update 
a local tree, but all that's gotten me is a mirror of the CVS tree, set 
up to distribute files as opposed to run a horde system.  Not much clue 
how to get from "ok, I've got the files" to "now I have a running 
system".  Many of the files appear to be optional, extraneous, or not 
in the directory they would be in for a working installation.

I suppose if I understood how to arrange the files for a working 
configuration, it would be easier to understand how to update an 
installation from CVS, but that's even less clear.

Applying the patches for the stable versions, while undocumented, 
wasn't too hard to figure out.  (You copy the patch file to the folder 
containing the installed program, then use patch -p1 < patchfile).  
Assuming that you left the .dist files in the config directory, you can 
now use diff <file>.php <file>.php.dist and figure out how to put your 
old configuration into the new file.  

(It would be great if someone came up with some sort of automation to 
preserve the old configuration while updating the config file and 
annotating new options...)
