genstruct is a system for marshalling/unmarshalling C structures. It
has a number of unusual features:

- can handle a very wide range of C constructs
- produces a human-readable marshalled format
- can handle significant changes in the structures between marshalling
  and unmarshalling
- works directly from C header files

To see how to use it please take a look at test.c and test.h. I'm
afraid that the only documentation at the moment is these examples.

Limitations
-----------

genstruct cannot handle some types of C structures. In particular it
cannot handle structures where a single pointer is used more than once
(for example in doubly linked lists). Once I add reference counting
this should be fixed.

A second problem is that genstruct works on the C headers before they
have been through the C pre-processor. This means that #ifdefs within
structures will screw things up badly.

Finally, genstruct only handles structure definitions if they are
formatted in a certain way. For example this will work:

GENSTRUCT struct foo {
	  char *s;
	  int x;
};

but this won't:

GENSTRUCT typedef struct {
	  char *s;
	  int x;
} foo;

This may be fixed in a future release.
