(input-method mr gamabhana)

(description "Based on Hindi input method by ITRANS and Harvard-Kyoto
transliteration systems.
You can use all the standard ITRANS key sequences plus key
sequences such as the below.

  nk->ङ्क्, nkh->ङ्ख्, ng->ङ्ग्, ngh->ङ्घ्
  nch->ञ्च्, nCh->ञ्छ्, nc->ञ्च्, nC->ञ्छ्, nchh->ञ्छ्,
  nj->ञ्ज्, njh->ञ्झ्, nT->ण्ट्, nTh->ण्ठ्, nD->ण्ड्, nDh->ण्ढ्
  c->च्, C->छ्, z->श्, S->ष्, jn->ज्ञ्, R->ऋ

In addition, for convenience, when a consonant + halant sequence
is followed by non Devanagari letter, the last halant is removed.
For instance, 'k SPC'->'क ', 'k..'->'क।'.

The motivation behind additions made to the basic ITRANS scheme
is described in http://sanskritnlp.appspot.com/optitrans.html,
along with a tabulated comparison with several other
transliteration schemes.

Also, see: http://en.wikipedia.org/wiki/Devanagari_transliteration.")
