Hi,

I am happy to inform, that Shrinivasan has created a python script to automate the process in Linux system. This scripts upload the PDF files to Google Drive, download the OCRed text and split, merge the text files properly to fit as the PDF file. We have just tested the script for small files in Kannad and Bengali Wikisource and it was successful. We are going to test the script for using different types and sizes of files and in other Indic languages in next few days.

The script is in https://github.com/tshrinivasan/OCR4wikisource
