 # Farhang Dictionary Production System (DPS)
 
-The purpose of this project is to typeset bilingual dictionaries. After typesetting, it provides options to export them to a specially crafted TeX file, which uses `farhang.cls` LaTeX class file for the layout of the TeX files. It also has a SQLite export feature to be used for writing dictionary apps.

-It is written in C# and uses MongoDB as database for storing dictionary entries as separate documents. It has been developed about 6 years ago and is very old. I used Mercurial (Hg) to manage the project, but converted the whole project from Mercurial to Git, just before making it free using hg-git plugin, mercurial package, python and bitbucket.

+years ago using Python, PostgreSQL and it was developed on Debian and was cross-compiled for windows. The current version has been developed about 6

-In order to run the project, you should install MongoDB and compile and run the project from source. I will try to provide a binary version for your convenience if I can find a suitable time.
