Known versions to verify downloads against.

Each element is a pipe-separated string of version|platform|sha256|length, where:

  • version is the version string
  • platform is one of [darwin,linux],
  • sha256 is the 64-character hex representation of the expected sha256
    digest of the download file, as emitted by shasum -a 256
  • length is the expected length of the download file in bytes

E.g., 3.1.2|darwin|6d0f18cd84b918c7b3edd0203e75569e0c7caecb1367bbbe409b44e28514f5be|42813.

Values are space-stripped, so pipes can be indented for readability if necessary.
