Welcome to Velocity!
As always, the if you have any questions :
1) Make sure you followed any directions :) (did you build everything?)
2) Review documentation included in this package, or online at
http://jakarta.apache.org/velocity
3) Ask on the velocity-user list. This is a great source of support information.
To join, read http://jakarta.apache.org/site/mail.html and then follow the
link at the bottom to join the lists.

Another simple example showing how to use Velocity in a standalone
program. This examples uses the org.apache.velocity.util.Velocity application utility
class, which provides a few convenient methods for application programmers. It also
should be precompiled for you. To run :
./example2.sh
