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.
