# extension provides cargo/rustc for building the launcher.

# The flatpak provides the sandbox and the WebKitGTK 4.1 / GTK3 runtime
# libraries that rlbotgui needs. RLBotServer and rlbotgui are downloaded from
# their GitHub releases by the launcher on every launch, so the pair stays in
# sync and neither repo's release cadence forces a flatpak rebuild. The only
# time this flatpak is re-released is when the launcher itself changes.
