sinhala_tex is a package of Metafont fonts and a preprocessor suitable
for writing Sinhala script using TeX or LaTeX.  This package
was originally developed by Yannis Haralambous
<Yannis.Haralambous@univ-lille1.fr>, with funding from the
Wellcome Institute for the History of Medicine, 183 Euston Road,
London NW1 2BE, England (Contact person: Dominik Wujastyk
<D.Wujastyk@ucl.ac.uk>), which is using the font in its
Catalogue of Sinhala Manuscript. The original package was
available by ftp at ftp.bcc.ac.uk in
/pub/users/ucgadkw/indology/software/sinhala1-TeX.zip

It was later modified by Vasantha Saparamadu <vsaparam@ocs.mq.edu.au>
to add support for 'samanala' transliteration scheme developed by
Prasad Dharmasena <pkd@isr.umd.edu>.
