VERSIONINFO="version 1.3, 7 june 1999, scott arrington"

# 27 July 1998
#	this places quotes (with a trailing newline in the quotes) around
#	each line of a file, making it suitable for use as a constant string
#	in C or C++.
#
#	the output of this script goes to stdout
#
# 19 Nov 1998
#	improved the thing to use a case statement that looks for
#	some standard arguments.  also allows you to specify
#	"-e", which makes the program escape any embedded quote
#	characters in the source file.
#
# 7 June 1999
#	better use of sed.  nothing major...
