phpDocumentor tags are very similar to tags for the JavaDoc tool for Sun’s Java Programming Language. Tags are only parsed if they are the first thing on a new line of a DocBlock. You may use the @ character freely throughout documents as long as it does not begin a new line. An example:
/**
* tags demonstration
* @author this tag is parsed, but this @version tag is ignored
* @version 1.0 this version tag is parsed
*/
