This module will transliterate Tamil language text. It is also used to transliterate Irula, Kota (India), Mannan, and Betta Kurumba. The module should preferably not be called directly from templates or other modules. To use it from a template, use {{xlit}}. Within a module, use Module:languages#Language:transliterate.

For testcases, see Module:ta-translit/testcases.
