=head1 info.pl
Show general information about this Virtualmin system.
This command is useful when debugging or configuring a system that you
don't know much about, to fetch general information about Webmin, Virtualmin,
IP usage and installed programs.
By default it outputs all available data, most of which is generated by
Virtualmin's background collection job that runs every 5 minutes. However,
you can limit it to a subset by adding command like parameters corresponding
to sections of the full output, for example:
~# virtualmin info host
host:
hostname: hostname.example.com
module root: /usr/share/webmin/virtual-server
os: Ubuntu Linux 22.04.2
root: /usr/share/webmin
theme version: 21.10
virtualmin version: 7.9.0.pro-1
webmin version: 2.105
