- Add a `spack gpg` subcommand in anticipation of signed binaries. - GPG keys are stored in var/spack/gpg, and the spack gpg command manages them. - Docs are included on the command.
GPG Keys
This directory contains keys that should be trusted by this installation of
Spack. They are imported when running spack gpg init, but may also be
imported manually with spack gpg trust path/to/key.
