From Express Computer article:
Prakash Advani, co-founder of IndLinux.org said that the organisation has been working on localising the GNU/Linux operating system to Hindi for the last three years. Localisation involves changing the menus and other elements of the graphic user interface from English to Hindi.
“Hindi is the third largest language in the world, yet there are no operating systems available in this language. IndLinux.org therefore decided to make Hindi support available for free to create a revolution in Indian language computing,” said Advani.
