+/**
+ * A parser implementation for FairMQ channel properties.
+ * The parser handles a comma separated key=value list format by using the
+ * getsubopt function of the standard library.
+ *
+ * The option key '--channel-config' can be used with the list of key/value
+ * pairs like e.g.
+ * <pre>
+ * --channel-config name=output,type=push,method=bind
+ * </pre>
+ *
+ * The FairMQ option parser defines a 'UserParser' function for different
+ * formats. Currently it is strictly parsing channel options, but in general
+ * the concept is extensible by renaming UserParser to ChannelPropertyParser
+ * and introducing additional parser functions.
