+The DWARF Debugging Information Format is of interest to programmers working on
+compilers and debuggers (and anyone 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 got involved with the committee
+and then developed the libdwarf and dwarfdump tools for SGI-internal use and as
+part of SGI IRIX developer tools. From around 1993 dwarfdump and libdwarf were
+shipped (as an executable and archive respectively, not source) with every
+release of the SGI MIPS/IRIX C compiler. In 1994 (I think the correct year) SGI
+agreed (at my request) to open-source libdwarf (and in 1999 to open-source
+dwarfdump) so anyone could use them.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
