# ad2c : Convert app-defaults file to C strings decls.
#
# DESCRIPTION
#      Ad2c  converts  X  resource  files  into   C   declarations,
#      appropriate  for  inclusion as fallback resources.
#      It reads from the given files (or stdin if none  are  given)
#      and writes the C declarations to stdout.

# CHANGE HISTORY
#	19 Mar 1991: gf
#		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
#       24 Feb 1994: david@ora.com (David Flanagan)
#		convert `!' comments to C-style comments.
#		output blank lines rather than deleting them.
#		this makes the output resemble the input a bit more.
#	30 May 1995: david@ora.com (David Flanagan)
#		an Xmt-specific change to comment out xmtRequires lines,
#		as suggested by Mike McGary.
#


# convert comments

# comment out xmtRequires lines, since we probably will run this script
# on those files too.  Only do this if the line is not \-terminated, since
# the multi-line case is too tricky and rare to bother handling correctly.
# Thanks to Mike McGary for this suggestion.

# ignore blanks

# escape backslash

# except the line continuation ones

# escape quotes

# add leading quote

# just like "read" only does not add leading quote
