That's this, right ?
http://techbase.kde.org/Projects/MovetoGit#Script_for_downloading_virtual_KDE_hierarchies:

Script for downloading virtual KDE hierarchies
0% completed (estimate)
  
Owner: 
Status: 
Let's start over on this. 
what we already have: two build scripts for kde; kdesvn-build and build-tool. 
what we want: an easy way for people to get large chunks of kde, without 
thinking about what urls the repos come from or having to look things up. 
do kde-svnbuild and build-tool satisfy this well enough? or do we want a 
computer-readable file listing all the repos too? 
btw, scripty has its own list of repos already. it's just in a rather weird 
bash file.

What does "large chunks of kde" mean ?
All (current) modules at once ?
Maybe CMake's external_project() feature in CMake >= 2.8.0 can do this ?
Documentation can be found here:
http://www.cmake.org/cmake/help/cmake-2-8-docs.html#module:ExternalProject
and page 10 of 
http://www.kitware.com/products/archive/kitware_quarterly1009.pdf

Basically you say something like the following:
ExternalProject_Add(
  CMake-2-6-4
  CVS_REPOSITORY :pserver:anonymous:cmake@
    www.cmake.org:/cvsroot/CMake
  CVS_MODULE CMake
  CVS_TAG -r CMake-2-6-4
  CMAKE_ARGS -DCMAKE_INSTALL_PREFIX:PATH=<INSTALL_DIR>
  )

This then checks out the sources from the given SCM, configures and builds it.
git is supported too, AFAIK.
