Re: [Bug-gnubg] Python (win) stuff

[Massimiliano Maini]

Actually I overestimated the impact on size, since the ziped python lib is 8Mb
because it's not compressed: once compressed it's much less.

Compared to a previuos install archive, the new one (with python 2.6.2 and
the whole python lib) is just 1Mb bigger and a lot comes from the python26.dll
being bigger than the 25 one (700Kb extra, uncompressed) and the 26 lib being
bigger than the 25 one.

Checking at instal time would be good, but could become a mess if the
installed python version changes wrt what gnubg has been compiled against.

I'm for having the installer to be sefl contained, even if tit wastes a few MBs
(download and disk space). Anyway, you won't need to download the full istaller
every day as soon as we reacha stable version: downloading the (most recent)
exes and slammng them into the directory will do the job.

MaX.
