+             xorriso under control of a (GUI) frontend process
+
+The dialog mode allows frontend programs to connect via pipes to the standard
+input and output of xorriso. Several commands of xorriso help with receiving
+and parsing of reply messages.
+
+As a proof of concept, there is the Tcl/Tk script xorriso-tcltk which can
+be launched by this shell command in the directory where xorriso was built:
+
+    xorriso/xorriso -launch_frontend frontend/xorriso-tcltk --stdio --
+
+resp. after installation:
+
+    xorriso -launch_frontend $(which xorriso-tcltk) --stdio --
+
+See file frontend/README-tcltk for a description of its GUI. 
+See its Tcl code for getting an idea how this gets achieved.
+
+Further there is the C program frontend/frontend_pipes_xorriso.c which
+forks a xorriso process and shows the same communication gestures as 
+xorriso-tcltk.
+In particular it connects to xorriso via two pipes, sends commands, waits 
+for all replies of a command, picks info out of the xorriso message sieve, 
+and parses reply message lines into words.
