   Example showing how to calculate pot equity using the enumeration functions.
   See also hcmp2.c and hcmpn.c for slightly lower level examples.

Note: games that use the joker are not yet implemented, though listed below.

Typical usage: 
$ pokenum [-mc niter] [-t] [-O]
          [-h|-h8|-o|-o8|-7s|-7s8|-7snsq|-r|-5d|-5d8|-5dnsq|-l|-l27]
          <pocket1> - <pocket2> - ... [ -- <board> ] [ / <dead> ]
      -t     terse output (one line, list of EV values)
      -O     compute and output detailed relative rank ordering histogram
      -mc    sample monte-carlo style instead of full enumeration
      -h     holdem hi (default)
      -h8    holdem hi/lo 8-or-better
      -o     omaha hi
      -o8    omaha hi/lo 8-or-better
      -7s    7-card stud hi
      -7s8   7-card stud hi/lo 8-or-better
      -7snsq 7-card stud hi/lo no stinking qualifier
      -r     7-card stud ace-to-5 low (razz)
      -5d    5-card draw hi (with joker)
      -5d8   5-card draw hi/lo 8-or-better (with joker)
      -5dnsq 5-card draw hi/lo no stinking qualifier (with joker)
      -l     5-card draw ace-to-5 lowball (with joker)
      -l27   5-card draw deuce-to-seven lowball

Streaming usage:
$ pokenum -i
followed by lines on stdin, one enumeration request per line, for example:
  -t -h Ac 7c - 5s 4s - Ks Kd
  -t -h Ac 7c - 5s 4s - Ks Kd -- 7h 2c 3h
  -t -h Ac 7c - 5s 4s - Ks Kd -- 7h 2c 3h 4d
  -t -mc 10000 -l27 5h 4h 3h / 5s Qd - 9s 8h 6d / Ks Kh

Use '-' between each player (optional in flop games).
Use '--' before the board (if any).
Use '/' before dead cards (can appear within a hand for discards).
Use 'Xx' for the joker.

Examples:

$ pokenum -h Ac 7c - 5s 4s - Ks Kd
$ pokenum -h Ac 7c 5s 4s Ks Kd
$ pokenum -h Ac 7c 5s 4s Ks Kd -- 7h 2c 3h

$ pokenum -o As Kh Qs Jh - 8h 8d 7h 6d
$ pokenum -o As Kh Qs Jh 8h 8d 7h 6d
$ pokenum -o As Kh Qs Jh 8h 8d 7h 6d -- 8s Ts Jc

$ pokenum -7s As Ah Ts Th 8h 8d - Kc Qc Jc Td 3c 2d
$ pokenum -7s As Ah Ts Th 8h 8d - Kc Qc Jc Td 3c 2d / 5c 6c 2s Jh

$ pokenum -l 7h 5s 3d Xx / Kd - 9s 8h 6d 4c / 8c
$ pokenum -l27 5h 4h 3h 2h / 5s - 9s 8h 6d 4c / Kd
$ pokenum -mc 10000 -l27 5h 4h 3h / 5s Qd - 9s 8h 6d / Ks Kh
