#9 (minor) typo in documentation section 5.2

[Gorbag]

The example given at the end of this section incorrectly uses '!boston' as a primitive task symbol. The correct primitive task symbol should be !drive with boston as the first argument (as in the preceeding text).

Thanks, fixed in our svn. When I push 2.9.1 to sourceforge, the fix will be there.
