Tim, all,

  Is this OK? I have run into this error with the script after cloning the
current repository:

01:02 archangel:/dat_e/tde> ./scripts/switch_all_submodules_to_head_and_clean
Preparing /dat_e/tde for development use

Entering 'experimental'
This script can only be run from a top level git directory.  Exiting...
Stopping at 'experimental'; script returned non-zero status.

  I presume this is OK, but wanted to check before I start down a path with a
messed up clone of the repository. What say the experts?

P.S. - How is the audiofile 3.2 -> 3.3 release and libpng 1.5.8 release
impacting current building?
