# This script processes raw page text into its final form for display.
# Invoke this command as follows:
#
# tclsh wrap.tcl $(DOC) $(SRC) $(DEST) source1.in source2.in ...
#
# The $(DOC) and $(SRC) values are the names of directories containing
# the documentation source and program source. $(DEST) is the name of
# of the directory where generated HTML is written. sourceN.in is the
# input file to be processed. The output is sourceN.html in the
# local directory.
#
# Changes made to the source files:
#
# * An appropriate header is prepended to the file.
# * Any
... in the input is moved into the prepended
# header.
# * An appropriate footer is appended.
# * Scripts within ... are evaluated. Output that
# is emitted from these scripts by "puts" appears in place of
# the original script.
