# 99 bottles of beer on the wall, Expect-style
# Author: Don Libes <libes@nist.gov>

# Unlike programs (http://www.ionet.net/~timtroyr/funhouse/beer.html)
# which merely print out the 99 verses, this one SIMULATES a human
# typing the beer song.  Like a real human, typing mistakes and timing
# becomes more erratic with each beer - the final verse is barely
# recognizable and it is really like watching a typist hunt and peck
# while drunk.

# Finally, no humans actually sing all 99 verses - particularly when
# drunk.  In reality, they occasionally lose their place (or just get
# bored) and skip verses, so this program does likewise.

# Because the output is timed, just looking at the output isn't enough
# - you really have to see the program running to appreciate it.
# Nonetheless, for convenience, output from one run (it's different
# every time of course) can be found in the file beer.exp.out
# But it won't show the erratic timing;  you have to run it for that.
