Automatic Rename Revit pdfs with revision information

hi, it is tedious to rename revit pdfs and add revisions as a suffix to company requirement. I just discovered automation tools called, Sikuli, jython(a script language), and itext java package for reading pdfs. It only took me half day to create the program to fetch drawing numbers and revision info then rename  the correspongding pdfs. the language is close to simple English and can run on vairious machines with out intallation. do a search and you can find them. and they are all free. Check the video below see how it works.
