# pretty printed output to the input file name.

# console rather than write it to the file, but no other debug messages.

# Set Debug to 2 for debug messages on entry and exit from subroutines and
# to not rename the input file iand write the output to the console rather 
# than the file for debugging. 

# Set Debug to 3 for very verbose debug messages.
