# This script is invoked by "commitinfo" just after the incoming file has 
# been uploaded to the server.  It gets passed these arguments:
#
#	tidy-bowl file ...
#
# If we approve of the commit for EVERY file in the list, then we return 
# a zero (0).  Any non-zero return aborts the commit, so we must be very
# careful here.
#
# AFAIK, the $PWD is the temporary file where the incoming "file" is located,
# but that needs to be verified.
#
# For every "file" that ends with ".xml", we will attempt to normalize the
# formatting by using tidy(1) to prettyprint it.  We must overwrite "file" so
# that the rest of CVS knows where to find the file.
#
# There doesn't seem to be any way to return error messages, so we'll just bang
# them out to "/var/log/messages".
