(input-method bn disha (version "1.6.1"))
(description "Bengali input method based on probhat layout.
Visual Based Bengali Keymap Layout created by Sayak Sarkar and proposed by Ankur Group (www.ankur.org.in) as part of Google Summer of Code, 2012.

Key summary:
To write \"juktakhor\" i.e. conjunct characters of consonants please use the \"halant\" character on the key '/' between the two consonant akshar.
E.g. ক্ষ = k+/+S
র্কি = r+/+i+k
ক্তি = k+/+i+f
To write two-part vowels please type the pre-base vowel followed by the consonant further followed by the post-base vowel.
E.g. কো = [+k+a
