Those programs are NOT what you want.  They do not find distant mates.  What
they *do* find is the shortest possible path to mates even in the most difficult
of problems for ordinary chess computer programs.  Some positions may be
Zugzwang or the like and the mate may not even be seen by an ordinary chess
program.  These mate solvers will absolutely find the most efficient possible
mate.  Some of them will produce an "audit trail" to demonstrate the mate.

If you want distant mates, just get a program with a tablebase and run some
sparse positions through it.

You can give Problemiste a try.  One warning, though.  It only reads white to
move EPD correctly.  But it does not make mistakes when you set the board up
manually.

There's another interesing one listed on KK's home page [IIRC] but I tried it
and it does not read EPD at all.
