Things still to do:

  - comma-separated training folders (-T spam1,spam2,spam3 nonspam1,2,3)
  20050131: option to set min token count before giving a score
  20050131: option to set max pruning count, not just 100,000
  20050131: investigate MySQL performance if read timers/counters added
  20050201: support for SQLite v3
  20050201: use static linking with SQLite library

Any assistance would be appreciated.
