Openkore is an advanced automated assistant (refer to Internet bot) for the MMORPG Ragnarok Online. The program is Free, Open Source and mainly written in Perl, but some code is also in c++. The perl-interpreter allows for a cross-platform usability (both Windows and Linux are supported officially). Openkore is licensed under the GNU General Public License GPL. Openkore's code is based on Skore-revamped, which is a fork of Kore developed by Kura. This unofficial project is in no way associated with Gravity (the company that developed Ragnarok Online).
