# @file GPG Configuration
# @brief Imports the public GPG key defined by the variable `KEYID` and then assigns it ultimate trust
# @description
# This script imports your publicly hosted GPG key using `pgp.mit.edu` as the key host. It then assigns it
# the ultimate trust level. It also downloads and configures GPG to use the configuration defined in `.config.gpg`
# in the `home/.chezmoidata.yaml` file.
