+# How to ignore bindata.go
+#     Due to irrational insistence of some Go developers, gofmt, like many
+#     other tools of Go ecosystem, does not have flags for common scenarios
+#     such as ignoring certain files by pattern etc. Thus we use `go list`
+#     and grep together to achieve the desired result.
+#
+#     The original query is this:
+#         gofmt -l $(go list -f $'{{range .GoFiles}}{{$.Dir}}/{{.}}\n{{end}}' ./... | grep -v bindata.go)
+#
+#     The original query is then escaped for Makefile (by repeating dollar signs $ -> $$).
