The project seems to be asleep but it's not.
A new version is in the making so stay tuned.
GRML is a swiss army knife for admin tasks and emergency recoveries.
The small version is CLI only and a selection of tools.
The large version also comes with a GUI and more tools.
But no matter what you prefer, GRML is a powerful project you should have in your toolbox.
Just get the image you prefer, dd it on a USB stick and you're ready to go.
Also consider similar projects like Finnix and SystemRescueCD.
These are also very powerful distros you should have so you're prepared in case of an emergency.
