# 2) Resolving any include file references
#
# 3) Building the data structures that depend on the file/dir names
# 3) Separating the command line into [options ... filenames ..]
# groupings so that user can interweave multiple options
# and names on the command line.
#
# 4) 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.
