    Proxy options:
        -d              run as a daemon (fork first, then run)
        -f              run as single-threaded server
        -i              run for inetd (socket on stdin/stdout)
        -q              suppress startup messages
        -c              Do not compress proxy <-> server connection

    General Options:
        -h -?           print this message
        -V              print server version

        -r cache        set proxy cache directory (default $P4PCACHE)
        -v level        debug modes (default $P4DEBUG)

        -L log          set error log (default $P4LOG, stderr)
        -p port         port proxy serves (default $P4PORT, 1666)
        -t port         port proxy uses to connect to a server
                                (default $P4TARGET, perforce:1666)
        -e size         proxy should only cache files larger than size
        -u service      Perforce user to authorize proxy

    Proxy certificate handling options:
        -Gc             generate private key and certificate and quit
        -Gf             display the fingerprint of the public key and quit

    Proxy monitoring options:
        -l [-s]         Show in-flight file requests to server (-s: summary)
        -v lbr.stat.interval=N
                        Set the file status interval in seconds (default 10)
        -v proxy.monitor.level=N
                        Set the proxy monitoring level:
                        0: monitoring disabled (default)
                        1: monitor file transfers only
                        2: monitor all operations
                        3: monitor all traffic for all operations
        -v proxy.monitor.interval=N
                        Set the monitoring interval in seconds (default 10)
        -mN             Show currently-active connections and their status
                        (requires -vproxy.monitor.level >= 1)
                        The optional argument specifies the level of detail,
                        where -m1 shows less detail, and -m3 shows the most.

    Proxy archive cache options:
        -S              Disable cache fault coordination
        -vnet.maxfaultpub=N     Set maximum size of coordinated cache faults
        -vlbr.proxy.case=N      Case folding:
                        1: file paths are always case-insensitive
                        2: file paths are insensitive if server is insensitive
                        3: file paths are never case-insensitive

                        When changing lbr.proxy.case, remove the existing
                        cache to ensure all cache contents obey the new
                        settings.
