mini-explor as described in the ken knowlton paper now exists on unix.
it is not totally cleaned up.

to use it:
1) create a file named 'filename.mx', where 'filename' is the name of
   your choice.
2) then just type:  'mx filename'.
   the file 'filename' should be a single fortran main program, without
   the 'stop' or 'end' cards.
   if an 'implicit integer /a-z/' statement is needed, it
   must be supplied by the user.
3) this file will be compiled, linked to mini-explor and executed.
   mx will print out 'i' and 'ii' on the screen as it works, and
   will clear the tektronix screen just as it starts.
4) overstriking is not yet implemented, and there may be a bug in
   the way the last line of the buffer is printed.
5) it is suggested that to fit on the screen, one use
	call put(37,17,73,33)
