%feature("docstring",
"Represents an executable image and its associated object and symbol files.

The module is designed to be able to select a single slice of an
executable image as it would appear on disk and during program
execution.

You can retrieve SBModule from :py:class:`SBSymbolContext` , which in turn is available
from SBFrame.

SBModule supports symbol iteration, for example, ::

    for symbol in module:
        name = symbol.GetName()
        saddr = symbol.GetStartAddress()
        eaddr = symbol.GetEndAddress()

and rich comparison methods which allow the API program to use, ::

    if thisModule == thatModule:
        print('This module is the same as that module')

to test module equality.  A module also contains object file sections, namely
:py:class:`SBSection` .  SBModule supports section iteration through section_iter(), for
example, ::

    print('Number of sections: %d' % module.GetNumSections())
    for sec in module.section_iter():
        print(sec)

And to iterate the symbols within a SBSection, use symbol_in_section_iter(), ::

    # Iterates the text section and prints each symbols within each sub-section.
    for subsec in text_sec:
        print(INDENT + repr(subsec))
        for sym in exe_module.symbol_in_section_iter(subsec):
            print(INDENT2 + repr(sym))
            print(INDENT2 + 'symbol type: %s' % symbol_type_to_str(sym.GetType()))

produces this following output: ::
