# Sourced, never run. Every value can be overridden from the environment before calling a script.
#
#   MGL_WORKTREE    MobileGL worktree (Windows form C:/...). Default: the worktree this skill lives in.
#   ANL_DIR         Local scratch dir: channel files, screenshots, xdist/. Default: %LOCALAPPDATA%/Temp/anl
#   ANDROID_NDK     NDK used for the Android server lib. Default: <SDK>/ndk/27.2.12479018
#   MGL_PKG         Anland APK that embeds the server. Default: com.anland.consumer.mobilegl
#   MGL_CONTAINER   Droidspaces container. Default: arch-kde-mgl
#   MGL_DESKTOP_USER  Desktop user inside the container. Default: swung0x48
#   DS_BIN          droidspaces binary on the phone. Default: /data/local/Droidspaces/bin/droidspaces
#   DEV_TOOLS       Phone dir for device/*.sh and channel files. Default: /data/local/tmp/anl
#   DEV_SHARE       Phone dir bind-mounted into the container as /run/anland-mobilegl (screenshots,
#                   server lib staging, display daemon socket). Default: /data/local/tmp/anland-mobilegl
#   ANDROID_SERIAL  Honored by adb itself; leave unset when only one device is attached
