ASC is a simple utility for converting text files (delimited with
\r, \n, or \r\n) to Windows format (\r\n delimited), Unix format
(\n delimited) or Mac format (\r delimited).

ASC is invoked from a DOS prompt with the command:

	> ASC {-m|u|w} file1 file2 ...

The optional switch specifies Mac processing (-m), Unix processing
(-u), or Windows processing (-w).  If no switch is specified, Windows
processing is performed.

Each file is processed in turn.  If the file is name.ext, the converted
file is name.new.
