#
# The CTANGLE program converts a CWEB source document into a C program that
# may be compiled in the usual way. The output file includes #line specifica-
# tions so that debugging can be done in terms of the CWEB source file.
#
# The CWEAVE program converts the same CWEB file into a TeX file that may be
# formatted and printed in the usual way. It takes appropriate care of typo-
# graphic details like page layout and the use of indentation, italics,
# boldface, etc., and it supplies extensive cross-index information that it
# gathers automatically.
#
# CWEB allows you to prepare a single document containing all the information
# that is needed both to produce a compilable C program and to produce a well-
# formatted document describing the program in as much detail as the writer
# may desire.  The user of CWEB ought to be familiar with TeX as well as C.
