[ILUG-BOM] Marathi on Linux (using Devnagari)

I am keen on using emacs mule utility for indian script say devnagari. I go to mule and select devnagari. What next. What is the layout of keyboard. Is it purely transliteration from english phionetically. Any examples, tutorials? Can some one send a specific adress so I can communicate. I am trying to create a group (including interested housewives and students and engg college teachers) to creat linux messages in Marathi.I would like to use Mule for that. Then I want to proiceed to marathi-ise internationalised versions of software. Would any one like to join. Please read Arth-Vrittant of 18 march which is a supplement to Loksatta. Jitendra
