</div>If it's true that there's no existing official documentation for the<br>
Java ffi (I'm not sure), I can write it one of these days, it<br>
shouldn't take long. It will be useful to me too (I always forget the<br>

In general abcl's documentation is<br>
indeed quite lacking; </blockquote><div><br>That is true regarding the documentation of its interaction with the jvm runtime environment<br>which is my primary focus of interest in ABCL. <br><br></div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
the implementation is young, the work force is<br>
scarce, and writing documentation is boring ;)<br></blockquote><div><br>We all know it and therefore honor voluntary efforts of developers!<br><br>Regards<br>Nik<br> </div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
