/*
* 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!
*
