# This sed script is used during the construction
# process to extract information from pre-processed
# source files.
#
# See, for example, the macro SCM_PROC.
#
# The effect of this script is to delete all lines
# from the input except for those between a line that
# contains "%%%" and a line that contains the matching
# "@@@" 
#
# The "%%%" are replaced by newlines and the "@@@" are
# deleted from the output.
