# boot_env -- Sets various openMSX settings based from environment variables.
#
# Typically used in automation tools which run openMSX without human interaction.
# Supported environment variables by this script;
#
# SAVE_SETTINGS_ON_EXIT=off
# Disables automatic settings saving.
#
# RENDERER=SDL
# Override video output from command line.
#
# SCALE_FACTOR=3
# Override video scale factor for SDL renderer.
#
# THROTTLE=off
# Disables msx speed emulation.
#
# SPEED=400
# Sets msx speed to 4x of original but only when throttle is on.
#
# JOYPORTA=mouse
# Inserts mouse in joyporta.
#
# JOYPORTB=mouse
# Inserts mouse in joyportb.
