pst2pdf run a TeX source, read all PS-related part and convert in images
	in pdf,eps,jpg or png format (default pdf) and create new file 
	whitout pst-environment and runs (pdf/Xe)latex. 
	See pst2pdf documentation for more info.
Options:
  -h,--help          - display this help and exit
  -l,--license       - display license information and exit
  -v,--version 	     - display version (current $nv) and exit
  -d,--dpi=<int>     - the dots per inch for images (default 300)
  -j,--jpg           - create .jpg files (need Ghostscript)
  -p,--png           - create .png files (need Ghostscript)
  -e,--eps	     - create .eps files (need pdftops)
  -s,--svg	     - create .svg files (need pdf2svg)
  -P,--ppm	     - create .ppm files (need pdftoppm)
  -a,--all	     - create .(pdf,eps,jpg,png,ppm,svg) images
  -c,--clear         - delete all temp and aux files
  -x,--xetex         - using (Xe)LaTeX for create images
  -m,--margins=<int> - margins for pdfcrop (in bp) (default 1)
  -ni,--noimages     - generate file-pdf.tex, but not images
  -np,--single       - create images files whitout preview and Ghostscript
  -ns,--nosource     - delete all source(.tex) for images files
  --imgdir=<string>  - the folder for the created images (default images)
  --ignore=<string>  - skip other verbatim environment (default other)
  --bibtex           - run bibtex on the aux file, if exists
  --biber            - run biber on the bcf file, if exists
  --Verbose          - creates a long log file (.plog)
  
Examples:
* $program test.tex -e -p -j -c --imgdir=pics
* produce test-pdf.tex whitout pstriks related parts and create image
* dir whit all images (pdf,eps,png,jpg) and source (.tex) for all pst 
* environment in "pics" dir using Ghostscript and cleaning all tmp files. 
* suport bundling for short options $program test.tex -epjc --imgdir=pics
