help acbot-words2 (continued from `help acbot-words1')

If one of your criteria to `words' is `/pattern', ACBot looks for words
containing the pattern.  Allowable patterns are made up of letters and:

^          Start of word
$          End of word
.          Any letter
[ar-u]     Any letter in `arstu'
[^ar-u]    Any letter not in `arstu'

Examples
  w 2 /^a                    2lws (2-letter words) starting with A
  w 5 /c.t                   5lws with C, then any letter, then a T
  w /ings$ /^[a-c]           words ending in INGS, beginning A B or C
  w /[^s]$ 8 >adeirt         8lws containing ADEIRT, without S at the end
