According to http://manual.phpdoc.org/HTMLframesConverter/default/

@property shows a "magic" property variable that is found inside the class.

The property is presumed to be available for both read and write operations. If the property is read-only, you should use the @property-read tag instead. If the property is write-only, use @property-write.

Example:

/**
 * show

Somebody needs to rewrite the French and the Japanese guides using the English guide as the source of truth.
