This module will transliterate Sanskrit language text per WT:SA TR. 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:sa-Beng-translit/testcases.
