+# SYNOPSIS
+#
+#   AX_LUAROCKS_ROCK([ROCK])
+#
+# DESCRIPTION
+#
+#   Checks for a rock, and fails if it is not installed.
+#
+#   Example usage:
+#
+#     AX_LUAROCKS_ROCK(stdlib)
+#
+#   Note: use of this macro is not normally recommended. Normally, LuaRocks
+#   should be used to drive the build system, and it takes care of rock
+#   dependencies. Use this macro only if LuaRocks cannot be used at the top
+#   level, for example, in a build system that uses Lua only incidentally.
