SCRIPT_EXPLAINER="Webmin is a web-based interface for system administration for Unix.
Using any modern web browser, you can set up user accounts, Apache, DNS, file sharing and much more.
Webmin removes the need to manually edit Unix configuration files like /etc/passwd, \
and lets you manage a system from the console or remotely.
See the following page with standard modules for a list of all the functions built into Webmin: \
