'''
`runmoore`, `runhex` and `runneumann` are demos to be played in a
80x24 terminal. The `output` function sets the output frequency.
runmoore(x=78, y=18, m=225)
runhex(x=39, y=18, m=112)
runneumann(x=78, y=18, m=225)
`slomobug` simulates a field known to trigger the bug discovered in
0.0.24 (fixed since 0.0.25).
`run623` is a generic field of 6x6x6 with 22 mines.
`run10` appears to be collecting some statistics of a 16x16 with 40 mines.

# BUG:
# sys.stdin.readline() in `ask` dies with IOError and
# errno=EINTR when the terminal gets resized after curses has
# been de-initialized.
# 1: SIGWINCH is sent by the terminal when the screen has been
# resized.
# 2: curses forgot to restore the signal handling of SIGWINCH
# to the default of ignoring the signal.
# NOTE: signal.getsignal(signal.SIGWINCH) incorrectly
# returns signal.SIG_DFL. (Default is to be ignored.)
# 3: Python fails to handle EINTR when reading from stdin.
# REFERENCES:
# Issue 3949: https://bugs.python.org/issue3949
# PEP 0457: https://www.python.org/dev/peps/pep-0475/
