Let me know the form you want the hierarchy to take, so
you can stick it into the GTK hierarchy thingy; I'll be
happy to crank out some quick yacc and lex code to do
the parsing of the file into that format for you.  A
structure definition, with links, and how you want it
linked, would be ideal.  8-).

Something like:

	typedef enum _nodekind {
		NK_VALUE,		/* Path component */
		NK_KEY,			/* Key */
		NK_DATA_INT,		/* 32 bit integer */
		NK_DATA_STRING,		/* String */
		NK_DATA_BINARY		/* Word count prefix bytestream */
	} nodekind_t;

	struct wcval {
		int16_t	count;		/* howw many bytes in "bytes" */
		char bytes[ 1];		/* actually longer */
	};

	struct node {
		struct node *parent;
		struct node *sibling;
		nodekind_t kind;
		union {
			struct node *child;
			int intval;
			char *strval;
			struct wcval *wcval;
		} u;
	};

But I could arrange something else, if it would be more useful
for it to be some other data structure.  ;-).
