/*
** KILLFF.C - A program was written to strip out all the Form Feeds
** in text files.
**
** Public domain by Erik VanRiper, 12/22/91
** Modified by Bob Stout, 17 Feb 93
**
** Reads a text file and makes a duplicate with NO Form Feed
** characters! The default action is to create a duplicate without
** Form Feeds, then remove the original and rename the dupliicate,
** although an explicit output file name may be specified.
**
** Form Feed characters are replaced with newline characters ('\n').
** Since ANSI mandates that fwrite() will translate newlines when
** a stream is opened in text (non-binary) mode, these will appear
** in the ouput file in a format appropriate to the implementation,
** e.g. CRLF pairs on PC's.
**
** Usage: KILLFF filename [newname]
