(description 
"pothana Telugu input method Version 2.0 date 24 Nov 2007
Telugu input method by Pothana layout and transliteration 
(key pairs have fixed one to one mapping), originally proposed by
Thirumala Krishna Desikachari along with Pothana font for Windows 
environments. 
For the detail of Pothana layout, see the telugu wikipedia page 
on Pothana font and download the paper available in that page
http://te.wikipedia.org/w/index.php?title=%E0%B0%AA%E0%B1%8B%E0%B0%A4%E0%B0%A8_%28%E0%B0%AB%E0%B0%BE%E0%B0%82%E0%B0%9F%E0%B1%81%29&oldid=188094.
the key mappings are in the last two pages of the paper.
Alt Key gives third level characters and 
Alt+shift key gives fourth level characters
Tested on Fedora core 6 under KDE with default US keyboard layout
Please give feedback/bugs to arjunaraoc@googlemail.com.
#change from previous version
base characters now give vowel endings than halanth
# 
Thanks for your help
