/*
* This is a stupid little program that can be used to convert 8-bit
* characters to and from backslashed escape sequences. It is usually
* more efficient to do this to affix files than to uuencode them for
* transport. Ispell will read affix files in either format, so it is
* merely personal preference as to which form to use.
*
* Usage:
*
* fix8bit {-7 | -8} < infile > outfile
*
* One of -7 and -8 must be specified. If -7 is given, any character
* sequence that is not standard printable ASCII will be converted
* into a backslashed octal sequence. If -8 is given, any backslashed
* octal or hex sequence will be converted into the equivalent 8-bit
* character.
*
* This program is not very smart. In particular, it makes no attempt
* to understand comments, quoted strings, or similar constructs in
* which you might not want conversion to take place. I suggest that
* you "diff" the input against the output, and if you don't like the
* result, correct it by hand.
