I finally managed to get a clean test run for assignment 6, but I still have to
grade the results. I will tell you when your grades are ready; do not bother
me for your grades before I tell you they are ready.

One person's code passed all the tests; another couple of people probably
passed all the tests once I get a chance to see why their code didn't work.

For those of you that are interested, what follows is an annotated script of
the test and the results of a perfect run. The script itself is indented two
spaces; comments are flush left.

Your program should always handle the empty case properly, which usually means
either printing an error message or generating code that handles no commands.
It does not mean core-dumping or producing code that doesn't compile.
  $ gen-cmds < /dev/null > cmds.cc
  $ g++ -c cmds.cc
A test to see if the empty input string was handled properly.  The output
should be "red", "white", and "blue".
  $ echo red white blue | gen-cmds > cmds.cc
  $ g++ -c cmds.cc
  $ g++ -o test-cmds ../../empty.cc cmds.o
A test to crash the code of people who've been ignoring my semester-long advice
to not use char * strings.
  $ echo 8192-character command | gen-cmds > cmds.cc
  $ g++ -c cmds.cc
A test to crash the code of people who use fixed-length arrays and then don't
bother to check to see when they're running off the end of the array.
  $ echo 8192 commands | gen-cmds > cmds.cc
  -rw-------   1 rclayton faculty    81475 Apr 17 11:40 cmds.cc
  $ g++ -c cmds.cc
A test to see how case-insensitive input was handled.  The output should be a
one of the five alphas, because duplicates should have been eliminated (if you
did it that way; a few people printed an error message and exited, which was
ok).
  $ echo Alpha aLpha alPha alpHa alphA | gen-cmds > cmds.cc
  $ g++ -o test-cmds ../../empty.cc cmds.cc
  $ test-cmds
  $ echo alpha | test-cmds
Same test as before, except without case conversions; the output should be one
alpha. 
  $ echo alpha alpha alpha alpha alpha | gen-cmds > cmds.cc
  $ g++ -o test-cmds ../../empty.cc cmds.cc
A test to see how well prefix matching was implemented.  Each input should
produce one less output than the test before; the first test should produce all
commands. 
  $ echo ! !@ !@# !@#$ !@#$% | gen-cmds > cmds.cc
  $ g++ -o test-cmds ../../empty.cc cmds.cc
  $ echo ! | test-cmds
  $ echo !@ | test-cmds
  $ echo !@# | test-cmds
  $ echo !@#$ | test-cmds
  $ echo !@#$% | test-cmds
  $ echo !@#$%^ | test-cmds
A test to see if people used extra files or not.
  $ ulimit -n 0 -f 0 ; test-cmds
A test to see if code managed memory properly.
  $ echo 1000 256-character commands | gen-cmds > cmds.cc
  -rw-------   1 rclayton faculty   265555 Apr 17 11:41 cmds.cc
  $ g++ -o exhaust-cmds ../../exhaust.cc cmds.cc
  $ exhaust-cmds
