=head1 NAME

fripost-newalias - Add a new alias to the system

=head1 SYNOPSIS

B<fripost-newalias> [B<--verbose>] [B<--debug>] [B<--pretend>]
[B<--force>] [I<goto> [I<from>...]]

=head1 DESCRIPTION

B<fripost-newalias> adds a new virtual alias to the system, unless
B<--pretend> is set.
If I<goto> or I<from> are not given, the user is prompted for them.
If I<goto> is not fully qualified, C<fripost.org> is appended.
If I<from> is already an existing username or alias,
B<fripost-newalias> raises an error.

Only simulates the insertion. (But still query the LDAP server to ensure
that the virtual domains of aliases are know, for example.)

Force creating the creation, even if I<from> is already an alias. Also,
disable the sending of the confirmation.

=item B<--server_host=>I<host>

The LDAP URI to connect to.
The default value is read from the configuration file, see B<CONFIGURATION>.

=item B<--bind_dn=>I<binddn>

The password to to bind with.
The default value is read from the configuration file, see B<CONFIGURATION>.

=item B<-v>, B<--verbose>

Verbose mode.
