-The libbacktrace library
-Initially written by Ian Lance Taylor <iant@google.com>
-
-The libbacktrace library may be linked into a program or library and
-used to produce symbolic backtraces.  Sample uses would be to print a
-detailed backtrace when an error occurs or to gather detailed
-profiling information.
-
-The libbacktrace library is provided under a BSD license.  See the
-source files for the exact license text.
-
-The public functions are declared and documented in the header file
-backtrace.h, which should be #include'd by a user of the library.
-
-Building libbacktrace will generate a file backtrace-supported.h,
-which a user of the library may use to determine whether backtraces
-will work.  See the source file backtrace-supported.h.in for the
-macros that it defines.
-
-As of September 2012, libbacktrace only supports ELF executables with
-DWARF debugging information.  The library is written to make it
-straightforward to add support for other object file and debugging
-formats.

-# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
-# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
-# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
-#
-# Of course, Automake must honor this variable whenever it calls a
-# tool from the auxiliary directory.  The problem is that $srcdir (and
-# therefore $ac_aux_dir as well) can be either absolute or relative,
-# depending on how configure is run.  This is pretty annoying, since
-# it makes $ac_aux_dir quite unusable in subdirectories: in the top
-# source directory, any form will work fine, but in subdirectories a
-# relative path needs to be adjusted first.
-#
-# $ac_aux_dir/missing
-#    fails when called from a subdirectory if $ac_aux_dir is relative
-# $top_srcdir/$ac_aux_dir/missing
-#    fails if $ac_aux_dir is absolute,
-#    fails when called from a subdirectory in a VPATH build with
-#          a relative $ac_aux_dir
-#
-# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
-# are both prefixed by $srcdir.  In an in-source build this is usually
-# harmless because $srcdir is `.', but things will broke when you
-# start a VPATH build or use an absolute $srcdir.
-#
-# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
-# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
-#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
-# and then we would define $MISSING as
-#   MISSING="\${SHELL} $am_aux_dir/missing"
-# This will work as long as MISSING is not called from configure, because
-# unfortunately $(top_srcdir) has no meaning in configure.
-# However there are other variables, like CC, which are often used in
-# configure, and could therefore not use this "fixed" $ac_aux_dir.
-#
-# Another solution, used here, is to always expand $ac_aux_dir to an
-# absolute PATH.  The drawback is that using absolute paths prevent a
-# configured tree to be moved without reconfiguration.

-Usage: $0 [OPTION]... [VAR=VALUE]...
-
-To assign environment variables (e.g., CC, CFLAGS...), specify them as
-VAR=VALUE.  See below for descriptions of some of the useful variables.
-
-Defaults for the options are specified in brackets.
-
-Configuration:
-  -h, --help              display this help and exit
-      --help=short        display options specific to this package
-      --help=recursive    display the short help of all the included packages
-  -V, --version           display version information and exit
-  -q, --quiet, --silent   do not print \`checking...' messages
-      --cache-file=FILE   cache test results in FILE [disabled]
-  -C, --config-cache      alias for \`--cache-file=config.cache'
-  -n, --no-create         do not create output files
-      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
-
-Installation directories:

-  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
-                          [PREFIX]
-
-By default, \`make install' will install all the files in
-\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
-an installation prefix other than \`$ac_default_prefix' using \`--prefix',
-for instance \`--prefix=\$HOME'.
-

-
-Some influential environment variables:
-  CC          C compiler command
-  CFLAGS      C compiler flags
-  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
-              nonstandard directory <lib dir>
-  LIBS        libraries to pass to the linker, e.g. -l<library>
-  CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
-              you have headers in a nonstandard directory <include dir>
-  CPP         C preprocessor
-
-Use these variables to override the choices made by `configure' or to help
-it to find libraries and programs with nonstandard names/locations.
-
-Report bugs to the package provider.

-/* This file declares various DWARF-related constants using a set of
-   macros which can be redefined by the including file.
-   
-   The macros are in sections.  Each section corresponds to a single
-   set of DWARF constants and has a corresponding key.  The key is
-   used in all the macro names.
-   
-   The sections are TAG (for DW_TAG_ constants), FORM (DW_FORM_), AT
-   (DW_AT_), OP (DW_OP_), ATE (DW_ATE_), and CFA (DW_CFA_).
-   
-   Using TAG as an example, the following macros may be used for each
-   key:
-   
-   DW_FIRST_TAG(name, value) - Introduce the first DW_TAG constant.
-   
-   DW_TAG(name, value) - Define a subsequent constant.
-   
-   DW_TAG_DUP(name, value) - Define a subsequent constant whose value
-   is a duplicate of some other constant.  Not all keys use the _DUP
-   macro form.  If more than one name shares a value, then the base
-   (DW_TAG) form will be the preferred name and DW_TAG_DUP will hold
-   any alternate names.
-   
-   DW_END_TAG - Invoked at the end of the DW_TAG constants.  */
