${title}Usage: $program <texfile.tex>  [Options]
pst2pdf run a TeX source, and convert all PS-related part as 
	single images  (pdf or eps or ppm, default pdf) 
	and then runs pdflatex. See pst2pdf documentation for more info
Options:
  --help          - display this help and exit
  --version       - display version information and exit
  --license       - display license information and exit
  --imageDir      - the dir for the created images (default images) 
  --DPI=<int>     - the dots per inch for a cretaed ppm files (default 75)
  --ppm           - create .ppm files
  --eps	  	      - create .eps files	
  --Iscale=<real> - the value for [scale=] in \\includegraphics 
  --noImages      - generate files without compile (need -norun)
  --verbose       - creates long log
  --clear         - delete all temp files
  --norun         - create file-pdf.tex, but, no run pdflatex
  --runBibTeX     - run bibtex on the aux file, if exists
  --runBiber      - run biber on the bcf file, if exists
  --files         - create images files (.tex) for all pst enviroment	
  --single	  - create images whitout pdftk and auto-pst-pdf
  --all	      	  - create all image type and images.tex	
  --nopdftk       - create all image type and images.tex in single mode
  --xetex         - using XeLaTeX for compilation.
Examples:
* $program test.tex --all
* produce test-pdf.tex and ppm,eps,tex and pdf for pst-enviroment in image dir
