It's now in the sbox2 git.

sb2 -m your_mode

sb2 -e is equivalent to running sb2 -m emulate

If you want to store your custom redir_scripts in $HOME/redir_scripts,
you could setup a bash alias:

alias sb2='sb2 -m your_mode -s $HOME/redir_scripts'

then run sb2 as usual. To make maintenance easier you could make
$HOME/redir_scripts/main.lua a symlink to the installed one.

The mapping cache may sometimes fail to update itself correctly, deleting
it manually from $BUILDROOT/.sb2cache will solve the problem. I'm working
on fixing this.
