console vCard address book
Khard is an address book for the console. By itself, it allows creating, reading, modifying, removing and searching for vCard address book entries (vcf files) in a directory on your local machine. Used in conjunction with vdirsyncer, it can be used to access and manage address books stored on a remote server via CardDAV. See https://khard.readthedocs.io/en/latest/scripting.html#integration for information about integrating with Mutt etc.
