+# c-graphqlparser
+
+This is a go-gettable version of the [libgraphqlparser](https://github.com/graphql/libgraphqlparser) C library for use in Go code that needs to link against the libgraphqlparser C library but wants to integrate with `go get` and `go build`.
+
+To use in your project you need to import the package and set appropriate cgo flag directives:
+
+```
+import _ "github.com/tecbot/c-graphqlparser"
+
+// #cgo CXXFLAGS: -std=c++11
+// #cgo CPPFLAGS: -I <relative-path>/c-graphqlparser/internal
+// #cgo darwin LDFLAGS: -Wl,-undefined -Wl,dynamic_lookup
+// #cgo !darwin LDFLAGS: -Wl,-unresolved-symbols=ignore-all
+import "C"
+```
+
+To update the upstream version of libgraphqlparser you'll want to run `./import.sh`.
