+#
+# SYNOPSIS
+#
+# AX_CHECK_VSCRIPT
+#
+# DESCRIPTION
+#
+# Check whether the linker supports version scripts. Version scripts are
+# used when building shared libraries to bind symbols to version nodes
+# (helping to detect incompatibilities) or to limit the visibility of
+# non-public symbols.
+#
+# Output:
+#
+# If version scripts are supported, VSCRIPT_LDFLAGS will contain the
+# appropriate flag to pass to the linker. On GNU systems this would
+# typically be "-Wl,--version-script", and on Solaris it would typically
+# be "-Wl,-M".
+#
+# Two Automake conditionals are also set:
+#
+# HAVE_VSCRIPT is true if the linker supports version scripts with
+# entries that use simple wildcards, like "local: *".
+#
+# HAVE_VSCRIPT_COMPLEX is true if the linker supports version scripts with
+# pattern matching wildcards, like "global: Java_*".
+#
+# On systems that do not support symbol versioning, such as Mac OS X, both
+# conditionals will be false. They will also be false if the user passes
+# "--disable-symvers" on the configure command line.
+#
+# Example:
+#
+# configure.ac:
+#
+# AX_CHECK_VSCRIPT
+#
+# Makefile.am:
+#
+# if HAVE_VSCRIPT
+# libfoo_la_LDFLAGS += $(VSCRIPT_LDFLAGS),@srcdir@/libfoo.map
+# endif
+#
+# if HAVE_VSCRIPT_COMPLEX
+# libbar_la_LDFLAGS += $(VSCRIPT_LDFLAGS),@srcdir@/libbar.map
+# endif
