  \brief \b (s)piapp: Starts the piapp interactive data analysis program.

  The current version of the program has a single execution thread. This
  creates few limitations (GUI can not be used when computing is being
  done, ...). Also the command file executed during start-up (-exec)
  cannot contain display (graphic) commands.

    -nosigfpe -nosigsegv: Don t catch SigFPE / SigSEGV
    -hidezswin : Hide Zoom/Stat/ColMap window
    -tmpdir TmpDirectory: defines TMDIR for temporary files
    -help2tex: Create a LaTeX help file (piahelp.tex)
    -exec file [args] : Execute command file
