Hehe, that's what I ended up doing, resorting to patterns and having
the parser try each of them out. Only my patterns are the following:

verb + direct object (i.e. get ball)
verb + indirect object (i.e. kill him)
verb + direct object + indirect object (i.e. give ball to him)
verb + indirect object + direct object (i.e. give him the ball)
verb + string (i.e. say 'hello everybody')

I believe all possible commands are simple variations of the above
mentioned patterns. Conjunctions merely compound the patterns.

The parser would handle conjunctions a bit differently. Basically,
"get ball and stick" would be broken down into "get ball" and
"get stick".
