+Subject: luci-lib-jsonc: Add ltn12-compatible sink factory
+
+To use the luci-lib-jsonc parser as sink for an ltn12 pump (for example
+from stdin), the following code will now do:
+
+    require 'luci.ltn12'
+    require 'luci.jsonc'
+
+    local parser = luci.jsonc.new()
+    luci.ltn12.pump.all(luci.ltn12.source.file(io.input()), parser:sink())
+    print(parser:get())
+
