Greg Peet and I have just launched the beta for Open-RJ (see http://openrj.sf.net/), which is a simple structured text format file reader, providing the Record-Jar format (described in "The Art Of UNIX Programming").

We've got a D mapping done already, but it's not included in the beta because it's in std/openrj.d, and I thought that was a little presumptuous. The C++, Ruby and STL mappings are included

The main lib is in 2 small, C files, depending only on std C headers, and file streams (i.e. fopen(), etc.).

Feel free to have a look, and I can post the D mapping here for experimentation if anyone's interested.
