/*
 * This module implements support for COM components that support the IDispatch
 * interface.  Both local (COM) and remote (DCOM) components can be accessed.
 *
 * Type libraries can be loaded (in order for PHP to recognize automation constants)
 * by specifying a typelib_file in the PHP .ini file.  That file should contain
 * paths to type libraries, one in every line.  By default, constants are registered
 * as case-sensitive.  If you want them to be defined as case-insensitive, add
 * #case_insensitive or #cis at the end of the type library path.
 *
 * This is also the first module to demonstrate Zend's OO syntax overloading
 * capabilities.  CORBA coders are invited to write a CORBA module as well!
 *
