-/**
- * Base class for other PEAR classes.  Provides rudimentary
- * emulation of destructors.
- *
- * If you want a destructor in your class, inherit PEAR and make a
- * destructor method called _yourclassname (same name as the
- * constructor, but with a "_" prefix).  Also, in your constructor you
- * have to call the PEAR constructor: $this->PEAR();.
- * The destructor method will be called without parameters.  Note that
- * at in some SAPI implementations (such as Apache), any output during
- * the request shutdown (in which destructors are called) seems to be
- * discarded.  If you need to get any debug information from your
- * destructor, use error_log(), syslog() or something similar.
- *
- * IMPORTANT! To use the emulated destructors you need to create the
- * objects by reference: $obj =& new PEAR_child;
