 link [OPTIONS]
 Link will compile a client and serve the resulting binary on a link which is returned.
 This requires the web server component has been enabled.
-	--fingerprint	Set RSSH server fingerprint will default to server public key
-	--garble	Use garble to obfuscate the binary (requires garble@master to be installed)
-	--goarch	Set the target build architecture (default runtime GOARCH)
-	--goarm	Set the go arm variable (not set by default)
-	--goos	Set the target build operating system (default runtime GOOS)
-	--http	Use http polling as the underlying transport
-	--https	Use https polling as the underlying transport
-	--name	Set the link download url/filename (default random characters)
-	--no-lib-c	Compile client without glibc
-	--owners	Set owners of client, if unset client is public all users. E.g --owners jsmith,ldavidson
-	--proxy	Set connect proxy address to bake it
-	--raw-download	Download over raw TCP, outputs bash downloader rather than http
-	--shared-object	Generate shared object file
-	--sni	When TLS is in use, set a custom SNI for the client to connect with
-	--stdio	Use stdin and stdout as transport, will disable logging, destination after stdio:// is ignored
-	--tls	Use TLS as the underlying transport
-	--upx	Use upx to compress the final binary (requires upx to be installed)
-	--working-directory	Set download/working directory for automatic script (i.e doing curl https://<url>.sh)
-	--ws	Use plain http websockets as the underlying transport
-	--wss	Use TLS websockets as the underlying transport
-	-C	Comment to add as the public key (acts as the name)
-	-l	List currently active download links
-	-o	Set owners of client, if unset client is public all users. E.g --owners jsmith,ldavidson
-	-r	Remove download link
-	-s	Set homeserver address, defaults to server --external_address if set, or server listen address if not
