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.")

file reading, a @emph{search path} with archives and directories is defined,
and it becomes a single, transparent hierarchical file system.  So archive
files can be accessed in the same way as you access files directly on a disk,
