 Sample uses would be to print a detailed backtrace when an error

 In general the functions provided by this library are async-signal-safe,
 meaning that they may be safely called from a signal handler.
+That said, on systems that use `dl_iterate_phdr`, such as GNU/Linux,
+gitthe first call to a libbacktrace function will call `dl_iterate_phdr`,

+that call libbacktrace from a signal handler should ensure that they
+make an initial call from outside of a signal handler.
+Similar considerations apply when arranging to call libbacktrace
+from within malloc; `dl_iterate_phdr` can also call malloc,
+so make an initial call to a libbacktrace function outside of
+malloc before trying to call libbacktrace functions within malloc.

-# These exist entirely to fool aclocal when bootstrapping libtool.
-#
-# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
-# which have later been changed to m4_define as they aren't part of the
-# exported API, or moved to Autoconf or Automake where they belong.
-#
-# The trouble is, aclocal is a bit thick.  It'll see the old AC_DEFUN
-# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
-# using a macro with the same name in our local m4/libtool.m4 it'll
-# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
-# and doesn't know about Autoconf macros at all.)
-#
-# So we provide this file, which has a silly filename so it's always
-# included after everything else.  This provides aclocal with the
-# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
-# because those macros already exist, or will be overwritten later.
-# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6. 
-#
-# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
-# Yes, that means every name once taken will need to remain here until
-# we give up compatibility with versions before 1.7, at which point
-# we need to keep only those names which we still refer to.
