Currently the latest SPD is based on Sage 3.4.2, this is the master
branch in our git repo:
http://github.com/certik/spd/tree/master
and all SPD patches are in the "spd" branch here:
http://github.com/certik/spd/tree/spd
e.g. if you click the history link, you get a list:
http://github.com/certik/spd/commits/spd/
Basically most of them are stuff like changing the banner, renaming
"sage" to "spd", and so on. One change that I did was that I unpacked
sage_scripts and keep it unpacked, then modified the install script to
pack the sage_scripts before installing, see this patch for details:
http://github.com/certik/spd/commit/efe29a35d2259522c7998e5a87b80340a3efb99a
Then all is needed when developing SPD is just change some files in
spkg/standard/sage_scripts/*, and it will just work. Previously I had
to unpack the sage_scripts.spkg, change it, and pack it again. With
the new way, I can keep everything in one (small) git repository.
