## Velocity template used to generate JSF1.2-compatible component classes
## from component meta-data.
##
## Note that there are two types of component generation:
##  * "subclass mode" (use annotated class as a parent class)
##  * "template mode" (use annotated class as a template)
## This template file is used for both.
##
## Variable $component refers to a ComponentMeta object to process
## Variable $utils refers to an instance of MyfacesUtils.
##
## When "template mode" is being used then variable $innersource
## holds a String containing all the non-abstract functions defined
## in the annotated class.
##
## The java package of the generated class is always the same as
## the package in which the annotated class exists.
