"""The DWARF Debugging Information Format is of interest to
programmers working on compilers and debuggers (and any one
interested in reading or writing DWARF information). It was
developed by a committee (known as the PLSIG at the time)
starting around 1991. Starting around 1991 SGI developed the
libdwarf and dwarfdump tools for internal use and as part of
SGI IRIX developer tools. Since that time dwarfdump and
libdwarf have been shipped (as an executable and archive
respectively, not source) with every release of the SGI
MIPS/IRIX C compiler."""
