# Made it self-contained.
# 6 Jan 1992 : mycroft@gnu.ai.mit.edu (Charles Hannum)
# Removed use of "-n" and ":read" label since Gnu and
# IBM sed print pattern space on "n" command. Still works
# with Sun sed, of course.
# 7 Jan 1992: matthew@sunpix.East.Sun.COM (Matthew Stier)
# Escape quotes after escaping backslashes.
# 8 Jul 1992: Version 1.6
# Manpage fixes.
# 19 Apr 1993: Version 1.7
# Remove comments that were inside the sed command since
# some versions of sed don't like them. The comments are
# now given here in the header.
#
# Comments on the script by line:
# /^!/d Remove comments
# /^$/d Remove blanks
# s/\\/\\\\/g Escape backslashes...
# s/\\$//g ...except the line continuation ones
# s/"/\\"/g Escape quotes
# s/^/"/ Add leading quote
# : test Establish label for later branch
# /\\$/b slash Branch to label "slash" if line ends in backslash
# s/$/",/ Otherwise add closing quote and comma...
# p ...output the line...
# d ...and clear the pattern space so it's not printed again
# : slash Branch comes here if line ends in backslash
# n Read next line, append to pattern space
# [...] The "d" and "s" commands that follow just delete
# comments and blank lines and escape control sequences
# b test Branch up to see if the line ends in backslash or not
