	  UUUUnnnnddddoooossss	and ttttoooouuuunnnniiiixxxx convert DOS or CP/M format source files to
	  Unix format by deleting carriage returns preceding linefeeds
	  and eliminating characters starting with CPMEOF (^Z).

	  TTTTooooddddoooossss	converts Unix format source files to DOS format	by
	  adding a carriage return (if not already present) before
	  each linefeed, and eliminates	characters starting with
	  CPMEOF (^Z).	TTTTooooccccppppmmmm additionally appends CPMEOF (^Z)
	  characters to	the resulting file to make the file length a
	  multiple of the 128 byte CP/M	record length.

	  Any combination of uuuunnnnddddoooossss,,,, ttttooooddddoooossss,,,, or ttttooooccccppppmmmm (without flags)
	  may be applied to a proper ASCII file	without	destroying
	  information.	Lone carriage returns used to force
	  overprinting are not translated to CR/LF pairs.

	  UUUUnnnnmmmmaaaacccc	converts files with lines terminated only by carriage
	  return to Unix format.  UUUUnnnnmmmmaaaacccc	should only be used to
	  translate files whose	lines are terminated by	lone carriage
	  returns.

	  TTTToooommmmaaaacccc	converts Unix format files to Macintosh	format (lines
	  terminated by	carriage return	only).

	  The optional flag ----ssss Strips the parity bit on	all characters
	  and discards all resulting characters	with values less than
	  7.

	  UUUUnnnnppppaaaarrrriiiittttyyyy strips the parity bit from each character and
	  writes the result unconditionally.

	  The access and modification times of the modified files are
	  set to those of the original files.

	  Without filenames, the programs act as filters.

	  Does not detect short	files without linefeeds.  UUUUnnnnmmmmaaaacccc	and

	  allows either	LF or CR/LF to delimit lines, but not CR.)
