 /**
  * 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;
