+# 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

+# is unlikely to handle the host's binaries.
+# Fortunately install-sh will honor a STRIPPROG variable, so we
+# always use install-sh in "make install-strip", and initialize
+# STRIPPROG with the value of the STRIP variable (set by the user).

+A User Manual is available under https://sourceforge.net/projects/irstlm
+The data for the examples described in the User Manual are available under http://sourceforge.net/projects/irstlm/files/irstlm/sampledata/
+
+HOW TO INSTALL
+
+step 0: sh regenerate-makefiles.sh [--force]
+# set parameter force to the value "--force" if you want to recreate all links to the autotools
+
+step 1: ./configure [--prefix=/path/where/to/install] ...
+# run "configure --help" to get more details on the compilation options
+
+step 2: make
+
+step 3: make install
+
+These steps will generate the irstlm library and commands, respectively,
+under the specified path where to install.

+# SYNOPSIS
+#
+#   AX_BOOST_BASE([MINIMUM-VERSION])
+#
+# DESCRIPTION
+#
+#   Test for the Boost C++ libraries of a particular version (or newer)
+#
+#   If no path to the installed boost library is given the macro searchs
+#   under /usr, /usr/local, /opt and /opt/local and evaluates the
+#   $BOOST_ROOT environment variable. Further documentation is available at
+#   <http://randspringer.de/boost/index.html>.
+#
+#   This macro calls:
+#
+#     AC_SUBST(BOOST_CPPFLAGS) / AC_SUBST(BOOST_LDFLAGS)
+#
+#   And sets:
+#
+#     HAVE_BOOST
+#

+# SYNOPSIS
+#
+#   AX_BOOST_THREAD
+#
+# DESCRIPTION
+#
+#   Test for Thread library from the Boost C++ libraries. The macro requires
+#   a preceding call to AX_BOOST_BASE. Further documentation is available at
+#   <http://randspringer.de/boost/index.html>.
+#
+#   This macro calls:
+#
+#     AC_SUBST(BOOST_THREAD_LIB)
+#
+#   And sets:
+#
+#     HAVE_BOOST_THREAD
