Your problem sounds interesting to me as well.  But I don't quite
understand it.  Is this following a representative test case?

  mkdir -p srcdir/proj1/CVS
  mkdir -p srcdir/proj1/foo1dir/CVS
  touch srcdir/proj1/foo1dir/foo
  mkdir -p srcdir/proj2/CVS
  mkdir -p srcdir/proj2/foo2dir/CVS
  touch srcdir/proj2/foo srcdir/proj2/foo2dir/bar
  mkdir -p srcdir/proj3/.svn
  mkdir -p srcdir/proj3/foo3dir/.svn
  touch srcdir/proj3/foo srcdir/proj3/foo3dir/bar
  mkdir -p srcdir/proj4/.git
  mkdir -p srcdir/proj4/foo3dir
  touch srcdir/proj4/foo srcdir/proj4/foo3dir/bar
  mkdir -p srcdir/subdir/proj5/.svn
  mkdir -p srcdir/subdir/proj5/foo5dir
  mkdir -p srcdir/subdir/proj6/.svn

Given that you are looking to list out the following directories?

  srcdir/proj1/CVS
  srcdir/proj2/CVS
  srcdir/proj3/.svn
  srcdir/proj4/.git
  srcdir/subdir/proj5/.svn
  srcdir/subdir/proj6/.svn

Is that right?

Using the above test case the following seems to work.

  find srcdir \( -exec test -d {}/CVS \; -o -exec test -d {}/.svn \; -o -exec 
test -d {}/.git \; \) -print -prune | sort

Produces:

  srcdir/proj1
  srcdir/proj2
  srcdir/proj3
  srcdir/proj4
  srcdir/subdir/proj5
  srcdir/subdir/proj6

Is that what you are looking for?
