  Description     : Selected Go-internal packages factored out from the standard library

 This repository factors out an opinionated selection of internal
 packages and functionality from the Go standard library. Currently
 this consists mostly of packages and testing code from within the Go
 tool implementation.
 .
 Included are the following: 
 .
  * dirhash: calculate hashes over directory trees the same way
        that the Go tool does.
  * goproxytest: a GOPROXY implementation designed for test use.
  * gotooltest: Use the Go tool inside test scripts (see testscript below).
  * imports: list of known architectures and OSs, and support for reading
        import statements.
  * modfile: read and write go.mod files while preserving formatting
        and comments.
  * module: module paths and versions.
  * par: do work in parallel.
  * semver: semantic version parsing.
  * testenv: information on the current testing environment.
  * testscript: script-based testing based on txtar files.
  * txtar: simple text-based file archives for testing.

Reason for packaging: Required by hugo 0.60.0+
