Re: git-changelog package?

Hi Simon,

OK, with your and Jim's consent, I've requested the creation of the project on
Savannah. Name: 'git-changelog'. We should ask for it to become a GNU project
later.

Yes, that would be good, to be claim copyright on 100% of the code.
For the initial code review of Savannah I've only included Jim's and
my code for now.

git-merge-changelog needs to be fast. When you have to rebase a series
of 30 patches, each step should take 1 second at most. You can spend
0.5 seconds on the ChangeLog file. So, the input are 3 files of ca. 2 MB
size, and you need it processed intelligently in 0.5 seconds. I don't
think Perl gives you this speed. (Jim's gitlog-to-changelog program
needs ca. 0.8 seconds to reformat the 1.5 MB of "git log" output. With
6 MB of input and more intelligent processing, I guess you cannot get
away with less than 5 seconds.)

Besides that, I won't write or maintain any Perl code.
