Comment (by SimonKing):
Replying to [comment:58 jhpalmieri]:
> Perhaps for a future version you might consider it, depending on how
much work it would be. A simple short-term solution would be to just
include html docs in the spkg; they shouldn't add too much to the size.
(Maybe a top-level directory `docs`, not under revision control.)
It is 3.4MB.
> Yes, that sounds good. Maybe also a list somewhere of which specific
calculations would make a good database.
Or perhaps another syntax would be better. My previous suggestion was:
"Declare during creation of a specific cohomology ring that it should go
into a data base." But the computation of one ring typically involves the
computation of rings for several subgroups (elementary abelian, Sylow,
...), and it would be reasonable to have them ALL in the data base.
Therefore, I think it would be better to have a ''global'' switch, for
example
{{{
sage: CohomologyRing.create_database("/path/to/data_base")
}}}
with the effect that all subsequent cohomology computations will work as
they usually do, but would additionally write the tar files into the given
data base folder.

Oops. I will try what happens with parallel make - after all, the comment
"Building in parallel is bad" is probably there for a reason (but I can't
recall).
> I'm going to browse the source a bit more, but it all looks very good
right now.
OK. Would it be OK to postpone the doc and data base additon, or would you
strongly prefer to have it in 2.1.2 already?
