this program takes a dos tape, and
extracts  files from tape, leaving them on
the current directory
	forrest howard, 8-75

	modifications by john burruss, 8-75:
		syntax is
	& dostape # [-]
		# is tape drive number (/dev/tap#)

		optional third arg means-- gimme only listing of filenames on
		the tape, don't extract any files

		the program does a 'dsw' style interactive extraction:
	 it types
		extract file.ext ?
	and the user replys "x"  for exit, "y" for extract, and
	anything else for skip file.
	before using this program you must get access
	to the appropriate tape drive with the "use" program.
	i.e.:

	& use dt# -shell
	...
	>&     (you now are in a sub-shell, with ownership
		of dectape number #, and now may run the dostape
		program.  remember to leave the subshell when
		done with the tape drive, so others may use it. --
		see help use)
