# Command line processing - Process any options set in the

#####
# Command Line Preprocessing
#
# Some things have to be done *before* the command line
# options can actually be processed. This includes:
#
# 1) Prepending any options specified in the environment variable.
#
# 2) Resolving any include file references
#
# 3) Building the data structures that depend on the file/dir names
# specified for renaming. We have to do this first, because
# -r renaming operations specified on the command line will
# need this information if they make use of renaming tokens.
