const usage = `Usage: %s
Create a single endpoint URL which clients can be pointed at.
The client-server API in Dendrite is split across multiple processes
which listen on multiple ports. You cannot point a Matrix client at
any of those ports, as there will be unimplemented functionality.
In addition, all client-server API processes start with the additional
path prefix '/api', which Matrix clients will be unaware of.
This tool will proxy requests for all client-server URLs and forward
them to their respective process. It will also add the '/api' path
prefix to incoming requests.
THIS TOOL IS FOR TESTING AND NOT INTENDED FOR PRODUCTION USE.
