Hello,

Sup's data is all contained in a single directory that defaults to
~/.sup. You can select the location of this directory with the SUP_BASE
env variable, so you could do something like:

SUP_BASE="$XDG_DATA_HOME/sup/postmaster" sup
SUP_BASE="$XDG_DATA_HOME/sup/sysadmin" sup
SUP_BASE="$XDG_DATA_HOME/sup/personal" sup

You must indicate a full path. Please note that you must specify the
SUP_BASE variable for each command, ie also for sup-add, sup-config, ...

I haven't tested it thoroughly (I just skimmed the source code and
tested with an empty dir), but would love to hear your findings if you
tried it.
