# KPJOY.DRV, the joystick driver the win16 port's Windows runs with:
# Windows 3.1 has the joystick API (joyGetPos and the rest) but ships no
# driver for it, so without one no stick is ever seen. Built
# (installer/lib/winDriver.sh) from the kpjoy project, a checkout beside
# this repository (../kpjoy, or KPJOY_DIR), into
# toolchains/opt/kpjoy/kpjoy.drv; scripts/lib/win16Gate.sh installs it in
# each run's Windows as MMSYSTEM's joystick driver.
