+## Available Lua CJSON specific workarounds
+#
+# To ensure JSON encoding/decoding works correctly for locales using
+# comma decimal separators, Lua CJSON must be compiled with one of
+# these options:
+# USE_POSIX_USELOCALE: Linux, OSX. Thread safe. Recommended option.
+# USE_POSIX_SETLOCALE: Works on all ANSI C platforms. May be used when
+#                      thread-safety isn't required.
+#
+# USE_INTERNAL_ISINF: Handle Solaris platforms that are missing isinf().
+
+# Tweak one of these platform sections below to suit your situation.
