syncReaders: Linux utility to synchronize Calibre & CoolReader database

I use the coolReader in my Android phone and tablet to read e-books. The e-books are managed in my Linux system using Calibre. One of the problem I had was that it was difficult to maintain the ratings and read status of the books across the three devices. Manually updating the ratings and read status was not practical. Since I go by "Machines should work and men should enjoy", some time ago I ventured into writing a program to synchronize the status and read status in both applications. I have been using the utility for a while and serves my purpose. The downside is that the database files of the applications have to be manually copied to Linux system for synchronization and then copy back to respective devices manually.
