From f7511d5f66f01fc451747b24e79f3ada7a3af9af Mon Sep 17 00:00:00 2001 From: Samuel Thibault Date: Wed, 30 Apr 2008 00:54:51 -0700 Subject: Basic braille screen reader support This adds a minimalistic braille screen reader support. This is meant to be used by blind people e.g. on boot failures or when / cannot be mounted etc and thus the userland screen readers can not work.
