+jfsw (source port of Shadow Warrior first-person shooter game)
+
+The aim of this port is to present Shadow Warrior as closely as possible
+to the original game while adding optional features to expand the
+possibilities of the game.
+
+To play the game, you will need the sw.grp data file from either the
+full or shareware DOS version of Shadow Warrior. If you want to play the
+shareware version, you can install jfsw_demo_data from slackbuilds.org.
+For the full version, copy sw.grp from the game directory to
+/usr/share/games/jfsw/sw.grp (the filename must be lowercase).
+
+If you have sw.grp from the full version of the game, you may also want
+to install jfsw_hires_pack for some graphic enhancements (don't bother
+trying, if all you have is the shareware sw.grp: it segfaults on startup).
+
+Mote #1: To hear the in-game music, install either eawpats (recommended)
+or freepats (both available at slackbuilds.org)
+
+Note #2: There's no way to enable the mouse from the in-game menus. To
+enable the mouse, you must run the game at least once to create its
+config file (~/.jfsw/sw.cfg), then edit the config file and change
+ControllerType to 1. You probably also want to change MouseAimingOn to 1,
+for a more modern "mouselook" style of play.
+
+Note #3: The Ambience setting in the Sound Setup menu is permanently
+disabled, because the ambience code causes the game to crash.
+
+Note #4: Multiplayer does work (at least for LAN play). See
+/usr/doc/jsfw-$VERSION/releasenotes.html for multiplayer usage.
+
+Note #5 (for Slackware 64-bit users): The source includes x86 assembly
+code, so can't be built for any non-x86 architecture. If you're using
+x86_64, you might (or might not) be able to build jfsw on a 32-bit
+Slackware system and install it on x86_64 along with alienBOB's or fred's
+-compat32 packages and get it to run.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description. Line
+# up the first '|' above the ':' following the base package name, and the '|'
+# on the right side marks the last column you can put a character in. You must
+# make exactly 11 lines for the formatting to be correct. It's also
+# customary to leave one space after the ':'.
