 * there is much left to do here before it can be useful for real world
 * programs
 * known problems:
 * -. Only one format of typelibs is supported
 * -. All testing so far is done using special written windows programs
 * -. Data structures are straightforward, but slow for look-ups.
 * -. (related) nothing is hashed
 * -. a typelib is always read in its entirety into memory and never released.
 * -. there are a number of stubs in ITypeLib and ITypeInfo interfaces. Most
 *      of them I don't know yet how to implement them.
 * -. Most error return values are just guessed not checked with windows
 *      behaviour.
 * -. all locale stuff ignored
 * -. move stuff to wine/dlls
 * -. didn't bother with a c++ interface
 * -. lousy fatal error handling
 * -. some methods just return pointers to internal data structures, this is
 *      partly laziness, partly I want to check how windows does it.
