This module will transliterate Bishnupriya Manipuri language text. 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:bpy-translit/testcases.

Functions
