Provide File Comment (PFC)

Description:

According to Sun Code Conventions for Java, all source files should begin with a C-style comment that lists the class name, version information, date, and copyright notice:

/*
 * Classname
 * Version information
 * Date
 * Copyright notice
 */

This audit rule verifies whether the file begins with a C-style comment. It may optionally verify whether this comment contains the name of the top-level class the given file contains.
