+# SYNOPSIS
+#
+#   AC_caolan_SEARCH_PACKAGE(PACKAGE, FUNCTION, LIBRARY LIST, HEADERFILE [, ACTION-IF-FOUND [, ACTION-IF-NOT-FOUND]])
+#
+# DESCRIPTION
+#
+#   Provides --with-PACKAGE, --with-PACKAGE-include and
+#   --with-PACKAGE-libdir options to configure. Supports the now standard
+#   --with-PACKAGE=DIR approach where the package's include dir and lib dir
+#   are underneath DIR, but also allows the include and lib directories to
+#   be specified seperately
+#
+#   adds the extra -Ipath to CFLAGS if needed adds extra -Lpath to LD_FLAGS
+#   if needed searches for the FUNCTION in each of the LIBRARY LIST with
+#   AC_SEARCH_LIBRARY and thus adds the lib to LIBS
+#
+#   defines HAVE_PKG_PACKAGE if it is found, (where PACKAGE in the
+#   HAVE_PKG_PACKAGE is replaced with the actual first parameter passed)
+#   note that autoheader will complain of not having the HAVE_PKG_PACKAGE
+#   and you will have to add it to acconfig.h manually
