I think almost any programmer will tell you the same, writing the manual or documentation for some work he has done (or is doing) is not the most fun part. So usually that part lacks a bit behind the program being made. For me that is also the case. Especially for the tools that are still in beta phase, the manual is often lacking or very minimal.
But today I changed that a bit, as I wrote a quick manual for the DrawCallMonitor tool I released a while ago. You can find this manual on the Wiki. Although it is a quite simple tool to use, I hope the manual provides a little more background information.
As this manual was short, it was easy to write. But I will promise you I will try to expand the ModelConverterX manual as well soon.
