#### Build tags
With the optional -tags flag, you can specify any go build tags that
must be fulfilled for the output file to be included in a build. This
is useful for including binary data in multiple formats, where the desired
format is specified at build time with the appropriate tag(s).
The tags are appended to a `// +build` line in the beginning of the output file
and must follow the build tags syntax specified by the go tool.
