# This is a wrapper script for the linux `rdesktop` command and
# is able to read .rdp files made with the Microsoft Terminal Services
# Client (mstsc)
#
# Currently, this version is far from being complete (I only implemented
# the most necessary variables) and it does not support reading from
# Unicode .rdp files, so please convert them to ASCII files first!
