print '''Routes are a way of either exclusively or mutually binding certain streams to certain playback clients. They are especially fitting in heterogenous environments where some clients will outperform others in certain pitches or with certain parts.
Routes are fully specified by:
-The attribute to be routed on (either type "T", or UID "U")
-The value of that attribute
-The exclusivity of that route ("+" for inclusive, "-" for exclusive, "!" for complete)
-The stream group to be routed there, or 0 to null route.
The first two may be replaced by a single '0' to null route a stream--effective only when used with an exclusive route.
"Complete" exclusivity is valid only for obligate polyphones, and indicates that *all* matches are to receive the stream. In other cases, this will have the undesirable effect of routing only one stream.
The special group ALL matches all streams. Regular expressions may be used to specify groups. Note that the first character is *not* part of the regular expression.
The syntax for that specification resembles the following:
broadcast.py -r U:bass=+bass -r U:treble1,U:treble2=+treble -r T:BEEP=-beeps,-trk3,-trk5 -r U:noise=0
The specifier consists of a comma-separated list of attribute-colon-value pairs, followed by an equal sign. After this is a comma-separated list of exclusivities paired with the name of a stream group as specified in the file. The above example shows that stream groups "bass", "treble", and "beeps" will be routed to clients with UID "bass", "treble", and TYPE "BEEP" respectively. Additionally, TYPE "BEEP" will receive tracks 4 and 6 (indices 3 and 5) of the MIDI file (presumably split with -T), and that these three groups are exclusively to be routed to TYPE "BEEP" clients only (the broadcaster will drop the stream if no more are available), as opposed to the preference of the bass and treble groups, which may be routed onto other stream clients if they are available. Finally, the last route says that all "noise" UID clients should not proceed any further (receiving "null" streams) instead. Order is important; if a "noise" client already received a stream (such as "+beeps"), then it would receive that route with priority.'''
