I like counting unique lines as a lower bound, since that eliminates a lot of redundancy (e.g., r""" lines for all docstrings). I get just over 300,000 doing that: teragon:sage wstein$ cat *.py */*.py */*/*.py */*/*/*.py *.pyx */*.pyx */*/*.pyx */*/*/*.pyx *.pxd */*.pxd */*/*.pxd */*/*/*.pxd |sort |uniq |wc -l cat: *.pyx: No such file or directory cat: *.pxd: No such file or directory 343084 But there are indeed a lot of lines of code to deal with! > > Algebras > - "has been hardly touched since" sounds pessimistic.

That sentence was not about all algebras code, but about free_algebra's, which indeed has hardly been touched. > > Combinat > - Is there a good quote by the combinat people about how happy they > are to have switched? After all, we're trying to sell switching. I don't have such a quote. > - It doesn't come across very strong that more than just porting > has been going on. I actually have the impression that not much beyond "just porting" has been going on. Somebody who knows better should correct me if I'm wrong (but I don't see "just porting" as unimpressive, personally). The only thing I know about is Dan Bump's work and the words library. I've added something about the words library. > > Ext > - Yes, we should remove all of the python_* files now that they're > shipped with Cython.
