steamcmd binary package in Ubuntu Lunar i386

 Steam (http://www.steampowered.com) is a software content delivery system
 developed by Valve software (http://www.valvesoftware.com). There is
 some free software available, but for the most part the content delivered
 is non-free.
 .
 The Steam Console Client or SteamCMD is a command-line version
 of the Steam client. Its primary use is to install and update various
 dedicated servers available on Steam using a command-line interface.
 .
 This package comes with a fairly substantial non-free license agreement
 that must be accepted before installing the software. If you have any
 opposition to non-free work, please select "I DECLINE" during the package
 installation dialogs.
