Software Download

   Welcome to the software Download page. The software here refers to the applications developed at IIT Madras as part of the Multilingual User Interface Design project. The applications available for free download are grouped into different categories, based on the use and area of application. For most of the applications, there is a brief description of the program and a link to the page where the application is described. 

  For most applications, the accompanying Readme file will provide basic information about the package and instructions for downloading and installing the package. Source code is provided for many utilities so that one might enhance the utility to suit specific requirements.

   Almost all the applications given here have been developed at the Systems Development Laboratory, Department of Computer Science and Engineering, IIT Madras to help the poor and underprivileged persons in India learn the use of computers and interact with a system in their own mother tongue. While IIT Madras cannot claim to have done anything to match the capabilities and features of commercial applications, the software is unique in providing the best possible approach to computing with Indian languages. You may also look at the on-line demos presented at this site to convince yourself that the IITM Software is indeed different in its approach to providing effective user interfaces in Indian languages.

The copyright for all the multilingual applications available for download from these pages is held by IIT Madras.

  During 2005, the IITM Software development effort has become an Open Source project at Sourceforge with licensing under GPL. Please consider contributing to this effort.

Working with the Sources

The applications made available for download have been compiled with appropriate development software. While such software is freely available for the Linux platform, one has to work with development environments which are priced under Win9X/2000/XP platforms. Typically, the Visual C++ development platform has been used for the applications running under Windows.
 

If you find bugs in the software, feel free to report them to the team at SDL. Better still, ask for the Sources and see if you can fix the bug for us.
