-# SYNOPSIS
-#
-# AX_LIB_EXPAT([MINIMUM-VERSION])
-#
-# DESCRIPTION
-#
-# This macro provides tests of availability of Expat XML Parser of
-# particular version or newer. This macro checks for Expat XML Parser
-# headers and libraries and defines compilation flags
-#
-# Macro supports following options and their values:
-#
-# 1) Single-option usage:
-#
-# --with-expat -- yes, no, or path to Expat XML Parser
-# installation prefix
-#
-# 2) Three-options usage (all options are required):
-#
-# --with-expat=yes
-# --with-expat-inc -- path to base directory with Expat headers
-# --with-expat-lib -- linker flags for Expat
-#
-# This macro calls:
-#
-# AC_SUBST(EXPAT_CFLAGS)
-# AC_SUBST(EXPAT_LDFLAGS)
-# AC_SUBST(EXPAT_VERSION) -- only if version requirement is used
-#
-# And sets:
-#
-# HAVE_EXPAT
-#
-# LAST MODIFICATION
