On operating systems with unusual path layouts, such as Exherbo and
NixOS, the de facto standard path for the runtime linker is not
necessarily present for all architectures.

(Of course, if the x86_64 runtime linker is not present, we won't
normally be able to run steam-runtime-system-info either, but at least
users of such operating systems can compile it from source code if they
need to provide diagnostics.)

steam-runtime-tools — Steam Runtime integration for the Steam client

The steam-runtime-tools library provides low-level Unix-specific tools and functionality for the Steam client, including the pressure-vessel tool that runs Steam games in containers.

To support multiple architectures (currently only i386 and x86_64 are supported), you will need to build it once for each architecture and install at least the helper tools in /usr/libexec/steam-runtime-tools-0 (the libsteam-runtime-tools-0-helpers package) for every architecture in parallel.

The helper tools are located relative to the shared library, so it's OK to bundle steam-runtime-tools alongside some other stack in this layout:

anything/
    lib/
        x86_64-linux-gnu/
            libsteam-runtime-tools-0.so.0
    libexec/
        steam-runtime-tools-0/
            i386-linux-gnu-*
            x86_64-linux-gnu-*

as long as the program that is linked to libsteam-runtime-tools-0.so.0 can find it (via a RPATH or RUNPATH or by setting the LD_LIBRARY_PATH environment variable).

pressure-vessel — putting Steam in containers

The pressure-vessel/ subdirectory of this project contains the pressure-vessel utilities, which are used by Steam's Steam Linux Runtime compatibility tool to run games in individual game-specific containers. For background on pressure-vessel and SteamLinuxRuntime, please see:
