In my flows, the "bundle" is a CVS module. CVS keeps track of  
sources, and ignores the fungus that grows around them (netlists,  
backup files, logs, etc.). The key thing is to keep every symbol  
except completely generic ones (like gnd-1.sym) in some directory in  
the module. Use relative pathnames in makefiles and gafrc files to  
establish relationships (sometimes I also use soft links). So,  
typically, a project "silistat" will have directories:

silistat/schematic
silistat/symbols
silistat/doc

etc. Lots of ways to do the details.

The klunky thing right now is importing symbols. Lots of:

locate thingie-1.sym
cp wherever/thingie-1.sym ../symbols/mythingie.sym

Then remember to rescan directories in the symbol browser (@#$%),  
choose and place the symbol, Hs, customize as needed, fs, Hu, ep. Or,  
if you imported a schematic and got the dreaded red triangle, import  
the missing symbol as above, rescan (this wasn't necessary in older  
versions), pr, yes I really want to, and then you're probably OK.

Yes, it's klunky, but in a big project it saves a lot of time down  
the road.
