SUMMARY="An Infinity Engine Emulator"
DESCRIPTION="GemRB (Game Engine Made with preRendered Background) \
is a new implementation of the original Infinity Engine \
(used in Baldur's Gate, Icewind Dale, Planescape: Torment etc.) \
to Linux/Unix, MacOS X, Windows (and Haiku) with some enhancements.
Original games' data is not included.

Haiku specific paths:
* /boot/system/settings/gemrb is where 'GemRB.cfg' is stored, edit this configuration file \
to point GemRB to the data of the game you want to play and to customize your GemRB setup.
* ~/config/settings/gemrb is the default folder for saves
* ~/config/cache/gemrb is the default folder for GemRB's log and temporary files"
