SBTarget supports module, breakpoint, and watchpoint iterations. For example,
for m in target.module_iter():

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:

For example,
process = target.Launch(self.dbg.GetListener(), None, None,
None, '/tmp/stdout.txt', None,
None, 0, False, error)
launches a new process by passing nothing for both the args and the envs
and redirect the standard output of the inferior to the /tmp/stdout.txt
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
inferior. Also, we ask the debugger not to stop the inferior at the
entry point. If no breakpoint is specified for the inferior, it should
run to completion if no user interaction is required.
