+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, Sun audio for samples, etc.).
+Conversely, when it reads files for inclusion in pwads, it does the necessary
+conversions (for example, from PPM to Doom picture format).  In addition,
+DeuTex has functions such as merging wads, etc.")
