Tag Plugin Implementation

## How to write tag plugins

To write a plugin, you'll need to download the source for Tomcat 5. There are two steps:

1. Implement the plugin class.

   This class, which implements `org.apache.jasper.compiler.tagplugin.TagPlugin` instructs Jasper what Java codes to generate in place of the tag handler calls. See Javadoc for `org.apache.jasper.compiler.tagplugin.TagPlugin` for details.
2. Create the plugin descriptor file `WEB-INF/tagPlugins.xml`

   This file specifies the plugin classes and their corresponding tag handler classes.
