13 for a data file format for C++ that was easy for both humans and
15 development, and that provided some compatibility with AI languages
16 such as Prolog and LISP.
18 The result was the wxExpr library (formerly called PrologIO), which is able to read and write a
19 Prolog-like attribute-value syntax, and is additionally capable of
