+
+A command line interface to an Ingen server. A command can be given directly
+on the command line, or when run with no arguments an interactive shell is
+launched.
+
+Options:
+ -s ADDRESS The address of the Ingen server. Default is the local server
+ at unix:///tmp/ingen.sock but remote servers can be used with
+ an address like tcp:///my-ingen-server-host:16180
+
+Commands:
+ put SUBJECT BODY
+ set SUBJECT KEY VALUE
+ connect TAIL HEAD
+ disconnect TAIL HEAD
+ patch SUBJECT REMOVE ADD
+ delete SUBJECT
+ help
+ exit
+
+Subjects are specified by URI, relative to the engine. The top level audio
+graph has the path /main, so for example, a port on a block might have the
+(relative) URI /main/osc/freq.
+
+Bodies are specified in fragments of Turtle, just as written in Ingen graph files.
+
+Example:
+ put /main/left_in 'a lv2:InputPort ; a lv2:AudioPort'
+ put /main/left_out 'a lv2:OutputPort ; a lv2:AudioPort'
+ put /main/tone 'a ingen:Block ; lv2:prototype <http://drobilla.net/plugins/mda/Shepard>'
