# Provided under GNU GPL version 2 or later.
#
# This is mainly a proof of concept for xorriso serving under a frontend.
# It exercises several fundamental gestures of communication:
# - connecting via two named pipes
# - sending commands
# - receiving replies
# - inquiring the xorriso message sieve
# - using the xorriso parsing service
# Note that any other language than Tcl/Tk could be used, if it only can
# do i/o via standard input and standard output or via named pipes.
# Further it has to perform integer arithmetics and string manipulations.
# And, well, a graphical widget set would be nice.
