<!--
This module demonstrates how to build a custom Velocity parser.
The proposed custom parser replaces '#' with '@' and '@' with '%'
so that it's suitable to use with Markdown template files, for instance.
The generated parser class is ${parser.package}.${parser.basename}Parser,
and must be specified at runtime using the Velocity property parser.class:
parser.class = foo.bar.MyCustomParser
Please note that all configurable chars (*, @, $, #) must be specified, even when similar to default ones.
