"Represents the target program running under the debugger.

SBTarget supports module, breakpoint, and watchpoint iterations. For example,

    for m in target.module_iter():
        print m

produces:

(x86_64) /usr/lib/system/libmathCommon.A.dylib
(x86_64) /usr/lib/libSystem.B.dylib(__commpage)

and,

    for b in target.breakpoint_iter():
        print b

produces:

SBBreakpoint: id = 1, file ='main.cpp', line = 66, locations = 1
SBBreakpoint: id = 2, file ='main.cpp', line = 85, locations = 1

and,

    for wp_loc in target.watchpoint_iter():
        print wp_loc

produces:

    Launch a new process by spawning a new process using the

    Arguments are given in argv, and the environment variables
    are in envp. Standard input and output files can be
    optionally re-directed to stdin_path, stdout_path, and
    stderr_path.

    @param[in] listener
        An optional listener that will receive all process events.
        If listener is valid then listener will listen to all
        process events. If not valid, then this target's debugger
        (SBTarget::GetDebugger()) will listen to all process events.

    @param[in] argv
        The argument array.

    @param[in] envp
        The environment array.

    @param[in] launch_flags
        Flags to modify the launch (@see lldb::LaunchFlags)

    @param[in] stdin_path
        The path to use when re-directing the STDIN of the new
        process. If all stdXX_path arguments are NULL, a pseudo
        terminal will be used.

    @param[in] stdout_path
        The path to use when re-directing the STDOUT of the new
        process. If all stdXX_path arguments are NULL, a pseudo
        terminal will be used.

    @param[in] stderr_path
        The path to use when re-directing the STDERR of the new
        process. If all stdXX_path arguments are NULL, a pseudo
        terminal will be used.

    @param[in] working_directory
        The working directory to have the child process run in

        Some launch options specified by logical OR'ing
        lldb::LaunchFlags enumeration values together.

    @param[in] stop_at_entry

    file. It does not specify a working directory so that the debug server
    will use its idea of what the current working directory is for the
