.Sh Name
.Nm authc
.Nd a client for the
.Xr authd 1
authentication daemon.

.Sh Description
.Nm authc
is a client for the
.Xr authd 1
daemon, a micro-service providing authentication and authorization services.

.Sh Synopsis
.
.Nm authc
.Op Fl h
.Ar COMMAND No
.Op Ar help
.Op Fl v Ar verbosity

.in

.Ar COMMAND No
can be:

.Bl -tag -width " print functions" -compact
.It Li bootstrap
Add the first user (an admin).
.It Li migration-script
Adding a batch of users from old code base.
.It Li user
Operations on users.
.It Li permission

.El

After the command is passed, you can always put the
.Ar -h No
flag to learn about the next parameters to give.

.Sh Configuration
Some parameters will reasonably come from a configuration file instead of the command-line interface, at least for
.Dq login
and
.Dq password .

By default, configuration is read from
.Pa $XDG_CONFIG_HOME/baguette/auth.yml
or
.Pa /etc/baguette/auth.yml ,
exactly as the
.Xr authd 1
daemon.

Configuration file is in YAML, see the following example:

.in +4
.nf
login: john42
password: banana
.fi
.in

In this example, the login and password of the user are set.
The
.Xr authc
application won't require them as command-line parameters for performing authenticated actions.

.Sh Configuration file variables
The following presents the complete list of configuration file variables.

.Bl -tag -width "Li password" -compact

.Dq 0
being quiet and
