=head1 NAME
nd-import-topology - Import a Nedisco 1.x Manual Topology File
=head1 USAGE
~/bin/localenv nd-import-topology /path/to/netdisco-topology.txt
=head1 DESCRIPTION
This helper script will read and import the content of a Netdisco 1.x format
Manual Topology file into the Netdisco 2.x database's C<topology> table.
It's safe to run the script multiple times on the same file - any new data
will be imported.
The file syntax must be like so:
left-device
link:left-port,right-device,right-port
The devices can be either host names or IPs. Data will be imported even if the
devices are currently unknown to Netdisco.
