# This script should be run nightly from cron. It checks out hdf5
# from the CVS source tree and compares it against the previous
# snapshot. If anything significant changed then a new snapshot is
# created, the minor version number is incremented, and the change is
# checked back into the CVS repository.

# The path isn't properly initialized on hawkwind -- /usr/local/bin is
# either missing or is after /usr/bin when it should be before.
