with my package maintainer hat on, I can say I much prefer a single 
package and it is easy enough for me to add an option to the package for 
including or not including the docs.


To put things in perspective, here is the rough breakdown of installed 
sizes:

total:  18.8 Mb

bin total: 4Mb.  This is roughly 2Mb for gschem, 1Mb for gattrib, 200 kB 
for gnetlist, 800 kB for the rest.

lib : 3.6 Mb

share : 11.2 Mb.  This is broken down to 5 Mb of documentation and 5.1 
Mb of symbols, about 500 kB of gnetlist scheme files, and the rest is 
all little files here and there.

So the biggest disk savings (by far) comes from skipping the 
documentation and also skipping the symbols.  This gets you down to 8.7 
Mb.  gschem+libgeda (which I think we can argue are core requirements 
and it doesn't make sense to skip either of these) makes up 5.6 of that 
8.7 so gnetlist, the utilities, gattrib, etc only takes about 3 Mb.

I see no real reason why we can't work towards a single unified build 
where you can use --disable-foo to disable optional components if so 
desired.

 From a developer and user of git or cvs sources point of view, I'd 
*much* rather run configure once instead of 9 (!) times.  Also parallel 
make jobs can work with the unified system which can really help with 
development speed.
