the first (as far as i know) open-source translator.
Prawda is an open-source project of machine translation. Developed by merely (at the time of writing) slavs, it's only in alpha stage now. At the moment it supports English->Russian and Esperanto->Russian direction of translation (both in alpha stage though the last is more mature).
This page is aimed to make available this piece of software to all people around the world who doesn't know Russian but is interested in such project. It is witten in plain C++ under UNIX environment. Unfortunately, all documentation of the project are in Russian only, but if you feel you can help us (by adding support for your native language and/or improving program's core), feel free to contact me and I'll translate docs into English.
