git svn with non-standard svn layout

[Fabian Molder <fm122@arcor.de>]

Hello,

- want to use git inside an huge SVN project
 --> so git-svn could do the job ..


- I struggle with two things:
   A) - the SVN project has an non-standard layout
   B) - want to have (several) git's for just the (few) peaces I work on

for A)
======
- svn layout looks like this (simplified):
  - trunk  (not really used, all interesting work in branches)
  - branches
    - r1.2
     - development
     - integration
    - r1.3
     - development
     - integration
    ...

- inside development and integration is:
       - xapplication1
       - xapplication2
       - xapplication3
       ...
       - aa
        -bb
         -cc
          - zapplication1
          - zapplication2
          - zapplication3
          ...

- I created an simplified svn test (from scratch; import/repo/workdir) 
  via this bash-script:   http://pastebin.ca/1608231

for B)
======
- the svn repo is very huge, but I'm only interested in these dirs:
         xapplication2/
         aa/bb/cc/zapplication1
- my objectives: 
   - have several local git's, just the ones I need:
     --> xapplication2/.git
     --> aa/bb/cc/zapplication1/.git


I tried to use "git config svn-remote.svn.branches" to do this,
 please see in function "do_git_svn" in bash-script - but no success

any hints appreciated 

regards,
Fabian
