DeuTex is a wad composer for Doom, Heretic, Hexen and Strife. It can be used to extract the lumps of a wad and save them as individual files. Conversely, it can also build a wad from separate files. When extracting a lump to a file, it does not just copy the raw data, it converts it to an appropriate format (such as PPM for graphics, .au for samples, etc.). When it reads files for inclusion in pwads, it does the necessary reciprocal conversions. In addition, DeuTex has functions such as merging wads, etc.
Design/CPN is a graphical tool supporting the use of Hierarchical Timed Coloured Petri Nets. The Editor supports construction, modification, and syntax check of CPN models. The Simulator supports interactive and automatic simulation of CPN models. The Occurrence Graph Tool supports construction and analysis of occurrence graphs for CPN models (also known as state spaces or reachability graphs). The Perfomance Tool supports simulation-based performance analysis of CPN models.
