+Brltty support for dracut
+
+This module provides brltty functionality in the initrd.
+Module pickups user settings from system and install
+necessary files like drivers and used text tables to initramfs.
+
+For now the module is reliably functional from phase pre-mount
+in earlier phases the module is not functional
+
+TBD fix functionality from earlier phases than pre-mount
+
+Module in instalation takes some options from environment variables.
+
+BRLTTY_DRACUT_INCLUDE_DRIVERS forces include of screen or braille
+driver
+example:
+BRLTTY_DRACUT_INCLUDE_DRIVERS=bpm beu
+
+BRLTTY_DRACUT_INCLUDE_TEXT_FILES forces include of text tables
+example:
+BRLTTY_DRACUT_INCLUDE_TEXT_FILES=kok.ttb lv.tti
+
+BRLTTY_LOCALE needs to be used when building initram image
+to install used text table 
+see https://bugzilla.redhat.com/show_bug.cgi?id=1584036
+example
+BRLTTY_LOCALE=cs_CZ.UTF-8
+
+Module allows to override some settings from grub
+mainly for debugging purposes
+
+brltty.braille_parameters
+example:
+brltty.braille_parameters="auth=none,host=IP:0"
+
+brltty.braille_driver
+example:
+brltty.braile_driver="ba"
