+elfcpp is a C++ library for reading and writing ELF information.  This
+was written to support gold, the ELF linker, and may not be generally
+useful.
+
+elfcpp does not do file I/O.  It deals only with offsets and memory
+data.
+
+For efficiency, most accessors are templates with two arguments: the
+ELF file class (32 or 64 bits) and the endianness.

+gold is an ELF linker.  It is intended to have complete support for
+ELF and to run as fast as possible on modern systems.
+
+It is written in C++.  It is (intended to be) a GNU program, and
+therefore follows the GNU formatting standards as modified for C++.
+Source documents in order of precedence:
+    http://www.gnu.org/prep/standards/
+    http://gcc.gnu.org/onlinedocs/libstdc++/17_intro/C++STYLE
+    http://www.zembu.com/eng/procs/c++style.html
+
+The linker is intended to have complete support for cross-compilation,
+which still supporting the normal case of native linking as fast as
+possible.  This makes the code more complex.
+
+Many functions are actually templates whose parameter is the ELF file
+class (e.g., 32 bits or 64 bits).  The code is the same, but we don't
+want to pay the execution time cost of always using 64-bit integers if
+the target is 32 bits.

+
+# 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.
