 * 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;
