# utlogger - execute autolog and make a running log file
#            using the log name CCYYMMDD.log in UTC time.
#
# This script executes autolog and make a log file with the
# name CCYYMMDD.log in the LogDir directory, where CCYYMMDD
# is the UTC Date.   This name is autogenerated by querying
# the system UTC clock (date -u).  If the file already exists, 
# it executes autolog -H (no header) and appends the log data,
# otherwise it generates a header as the first line of the log file.
#
# If you give no arguments on the command line, it pukes.
# If you give it a wildcard argument, it handles it just fine.
#
# This cript assumes the default format file.  If you want to change it,
# add the -Ffmtfile flag below.
#
# Set the LogDir enviroment variable below to set the source 
# directory.  If blank, it will assume the cwd, which might
# be bad.
