[Kde-scm-interest] Re: converting QMake plugin (was: importing subproject history)

[Nicolas Alvarez]

I'm trying to convert the KDevelop QMake plugin:

http://websvn.kde.org/trunk/playground/devtools/kdevelop4-extra-
plugins/qmake/?view=log

(That's the current path, it moved around a lot in previous revisions.)

'qmakebuilder' used to be in a separate directory, usually a sibling of 
'qmake' (other times a 'cousin' directory). Later, it was moved into 
/qmake/qmakebuilder.

I want to get the full history of both.

The problem with this solution is that there are many SVN commits that touch 
both qmake and qmakebuilder, and I'd like to keep those as atomic git 
commits too.

I thought of putting 'qmake' and 'qmakebuilder' as directories in the git 
repo, corresponding to the two projects in SVN. Then, in r972147, all files 
under qmake would move to the root of the git repo, and files in 
qmakebuilder would stay there. But I have no idea how to do this in svn2git, 
or if it's possible at all.

Ideas?
