switch_all_submodules_to_head_and_clean -> Stopping at 'experimental'; script returned non-zero status.

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 Enter your TDE GIT username []: drankin HEAD is now at 6df356b Reset submodule main/tdebase to latest HEAD Removing libqt-mt.so Removing libqt-mt.so.3 Removing libqt-mt.so.3.3 Already up-to-date.

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?
