This only applies to files named `LICENSE` specifically, without +extensions like `.txt`. Unfortunately, this cannot be extended without breaking +cryptographic sums of exesting modules; see [Authenticating +modules](#authenticating). Other tools and websites like +[pkg.go.dev](https://pkg.go.dev) may recognize files with other names. + +Note also that the `go` command does not include symbolic links when creating +module `.zip` files; see [File path and size +constraints](#zip-path-size-constraints). Consequently, if a repository does not +have a `LICENSE` file in its root directory, authors may instead create copies +of their license files in modules defined in subdirectories to ensure those +files are included in module `.zip` files. + ### Controlling version control tools with `GOVCS` {#vcs-govcs} The `go` command's ability to download modules with version control commands |
