Clearly I need to do some more reading...but where?
http://velocity.apache.org/engine/devel/developer-guide.html only says in
relation to #parse, "this may be used to make all includes relative to the
current directory". Where is the current directory set for Velocity? I got a
hold of Pro Jakarta Velocity (2004) but #parse was not mentioned.

Cheers,

Tom.
