=head1 NAME

B<lat-dump> - The lazy administrator's tool to extract config info

=head1 DESCRIPTION

Creates input-files for the lat-toolkit, based on the current configuration of the SME server (5.x/6.x). The information is extracted from the /home/e-smith/db/* databases.

The resulting input-files can be used to replicate user accounts, ibays, etc on a different SME server, or recreate them on a clean install. To facilitate the restoring/replicating, the lat-restore script is automatically created. This will launch the various lat-tools in the right sequence.

=head1 SYNOPSIS

B<lat-config> [options]

=head1 OPTIONS

The following options are supported:

=over 4

=item B<-d>, B<--dump>

Create input files

=item B<-h>, B<--help>

Extended help for this tool

=item B<-o=/path/>, B<--output-dir=/path/>

Directory where the configuration files should be stored. If omitted, the current directory is used.

=back

=head1 EXAMPLES

B<lat-dump -d -o=/var/tmp>

Creates the configuration files and writes them to /var/tmp.

=head1 SEE ALSO

lat-users(8), lat-group(8), lat-pseudonyms(8), lat-ibays(8), lat-quota(8), lat-domains(8), lat-hosts(8), lat-procmail(8), lat-pptp(8)

=head1 VERSION

Version 0.9.0 (2004-09-08). The latest version is hosted at B<http://www.contribs.org/contribs/mblotwijk/>
