# Annotation:  There had been the `OPTIMIZE' option included.  But:
# This resulted in a faulty version of `cweave' (`ctangle' worked fine).
# The `TeX' code produced by this version had a lot of extra `$' characters
# in various combinations with `cwebmac' macros, which made it impossible
# for \TeX\ to compile the results correctly.  Hopefully the version 6.1
# of the SAS/C optimizer will do a better job.

# It will be needed if you made additional changes to
