New Revision: 33304
URL: https://nixos.org/websvn/nix/?rev=33304&sc=1
Log:
Updating the script of loading myEnv environments, for something close to what
I was using.
It sets a fixed PS1, maybe breaking someone's taste, though. But I find it
easier to use.
Added:
nixpkgs/trunk/pkgs/misc/my-env/loadenv.sh
