***********************************************************************

Webmin is a web-based interface that allows Unix-like operating

systems and common Unix services to be easily administered.

Installing Webmin in /usr/local/lib/webmin …

Unless you want to run multiple versions of Webmin at the same time

you can just accept the defaults.

Log file directory [/var/log/webmin]: (Default press Enter Button)

***********************************************************************

Webmin is written entirely in Perl. Please enter the full path to the
