+lldb-server -- Server for LLDB Debugging Sessions
+=================================================
+
+.. program:: lldb-server
+
+SYNOPSIS
+--------
+
+| :program:`lldb-server` v[ersion]
+| :program:`lldb-server` g[dbserver] [*options*]
+| :program:`lldb-server` p[latform] [*options*]
+
+DESCRIPTION
+-----------
+
+:program:`lldb-server` provides the server counterpart of the LLVM debugger.
+The server runs and monitors the debugged program, while the user interfaces
+with it via a client, either running locally or connecting remotely.
+
+All of the code in the LLDB project is available under the Apache 2.0 License
+with LLVM exceptions.
+
+COMMANDS
+--------
+
+The first argument to lldb-server specifies a command to run.
+
+.. option:: v[ersion]
+
+ Prints lldb-server version and exits.
+
+.. option:: g[dbserver]
+
+ Runs the server using the gdb-remote protocol. LLDB can afterwards
+ connect to the server using *gdb-remote* command.
+
+.. option:: p[latform]
+
+ Runs the platform server. LLDB can afterwards connect to the server using
+ *platform select*, followed by *platform connect*.
+
+GDBSERVER COMMAND
+-----------------
+
+| :program:`lldb-server` g[dbserver] [*options*] [[*host*]:*port*] [[--] *program* *args*...]
+
+CONNECTION
+~~~~~~~~~~
+
+.. option:: host:port
+
+ Specifies the hostname and TCP port to listen on. Obligatory unless another
+ listening option is used. If host is empty, *localhost* will be used.  If port
+ is zero, a random port will be selected, and written as specified by --pipe
+ or --named-pipe options.
+
+.. option:: --fd <fd>
+
+ Communicate over the given file descriptor instead of sockets.
+
+.. option:: --named-pipe <name>
+
+ Write the listening port number to the specified named pipe.
+
+.. option:: --pipe <fd>
+
+ Write the listening port number to the specified pipe (fd).
+
+.. option:: --reverse-connect
+
+ Connect to the client instead of passively waiting for a connection. In this
+ case, [host]:port denotes the remote address to connect to.
+
+GENERAL OPTIONS
+~~~~~~~~~~~~~~~
+
+.. option:: --help
+
+ Prints out the usage information and exits.
+
+.. option:: --log-channels <channel1 categories...:channel2 categories...>
+
+ Channels to log. A colon-separated list of entries. Each entry starts with
+ a channel followed by a space-separated list of categories.
+
+.. option:: --log-file <file>
+
+ Destination file to log to. If empty, log to stderr.
+
+.. option:: --setsid
+
+ Run lldb-server in a new session.
+
+TARGET SELECTION
+~~~~~~~~~~~~~~~~
+
+.. option:: --attach <pid-or-name>
+
+ Attach to the process given by a (numeric) process id or a name.
+
+.. option:: -- program args
+
+ Launch a program for debugging.
+
+If neither of target options are used, :program:`lldb-server` is started
+without a specific target. It can be afterwards instructed by the client
+to launch or attach.
+
+PLATFORM COMMAND
+----------------
+
+| :program:`lldb-server` p[latform] [*options*] --server --listen [[*host*]:*port*]
+
+CONNECTION
+~~~~~~~~~~
+
+.. option:: --server
+
+ Run in server mode, handling multiple connections. If this is not specified,
+ lldb-server will accept only one connection and exit when it is finished.
+
+.. option:: --listen <host>:<port>
+
+ Hostname and port to listen on. Obligatory. If *port* is zero, a random port
+ will be used.
+
+.. option:: --socket-file <path>
+
+ Write the listening socket port number to the specified file.
+
+GENERAL OPTIONS
+~~~~~~~~~~~~~~~
+
+.. option:: --log-channels <channel1 categories...:channel2 categories...>
+
+ Channels to log. A colon-separated list of entries. Each entry starts with
+ a channel followed by a space-separated list of categories.
+
+.. option:: --log-file <file>
+
+ Destination file to log to. If empty, log to stderr.
+
+GDB-SERVER CONNECTIONS
+~~~~~~~~~~~~~~~~~~~~~~
+
+.. option:: --gdbserver-port <port>
+
+ Define a port to be used for gdb-server connections. Can be specified multiple
+ times to allow multiple ports. Has no effect if --min-gdbserver-port
+ and --max-gdbserver-port are specified.
+
+.. option:: --min-gdbserver-port <port>
+.. option:: --max-gdbserver-port <port>
+
+ Specify the range of ports that can be used for gdb-server connections. Both
+ options need to be specified simultaneously. Overrides --gdbserver-port.
+
+.. option:: --port-offset <offset>
+
+ Add the specified offset to port numbers returned by server. This is useful
+ if the server is running behind a firewall, and a range of ports is redirected
+ to it with an offset.
+
+EXAMPLES
+--------
+
+The server can be started in several modes.
+
+In order to launch a new process inside the debugger, pass the path to it
+and the arguments to the debugged executable as positional arguments.
+To disambiguate between arguments passed to lldb and arguments passed
+to the debugged executable, arguments starting with a - must be passed after
+--. The server will launch the new executable and stop it immediately, waiting
+for the client to connect.
+
+  lldb-server g :1234 /path/to/program program-argument -- --program-option
+
+For convenience, passing the executable after -- is also supported.
+
+  lldb-server g :1234 -- /path/to/program program-argument --program-option
+
+In order to attach to a running process, pass --attach along with the process
+identifier or name. The process will be stopped immediately after starting
+the server. Note that terminating the server will usually cause the process
+to be detached and continue execution.
+
+  lldb-server g :1234 --attach 12345
+  lldb-server g :1234 --attach program-name
+
+Use *gdb-remote* command to connect to the server:
+
+  (lldb) gdb-remote 1234
+
+lldb-server can also be started without an inferior. In this case, the client
+can select the target after connecting to the server. Note that some commands
+(e.g. *target create*) will disconnect and launch a local lldb-server instead.
+
+  lldb-server g :1234
+
+  (lldb) gdb-remote 1234
+  (lldb) process launch a.out
