===Dhvani TTS : Speech dispatcher driver and Orca integration===

Dhvani has generic driver for speech dispatcher and that is not efficient and cannot use many features of dhvani. Write a driver for speech-dispatcher and integrate it with Orca so that it works as Screenreader

=== Calender===

Create a calendrical calculation library that will be usable from Python/C++ programs. Writing a C++/C library and writing a Python wrapper for it is enough. This can be used to display Indian calendars on Free Desktops
