Generate a network topology
tracehost is a bash script that parses a standard hosts files and generates
an SVG. The script accepts a standard system hosts file format but actually it
only cares about the first host or IP on a line. In fact any line format may be
used as long as each line begins with something that can be pinged.

The image below is generated as a daily GitLab cron job. Hosts that don't respond to pings are coloured red.
