OSLite1. Introduction
Thanks for your interest in OSLite. OSLite is a free,lightweight,developing program for OpenSees visualization. I am very happy to have the opportunity to distribute this software for OSLite users. I encourage everyone to try out all of the functions of the program and send me criticism, corrections or suggestions to improve future versions. I also encourage users to e-mail me at "jacques dot chen At qq dot com".
I am very sorry, because there have been many things in my life in the past year. OSLite was not updated for the entire year. A new version is coming. very fast! Full of surprises.
Je suis vraiment désolé, car il y a eu beaucoup de choses dans ma vie au cours de la dernière année. OSLite n'a pas été mis à jour pour toute l'année. Une nouvelle version est à venir. Très vite! Plein de surprises.
非常抱歉，这么长时间我都没有更新OSLite。过去一年，我的生活中发生了许多事。一个全新的版本很快就会发布，充满惊喜！
