Can anyone explain to me the rationale of Dump dropping acme.dump in $HOME
instead of $PWD?
I know I can pass it a different filename, but it seems odd to put it in
$HOME instead of where acme is called from.
My use case is this: I'm working on two projects, and so want to maintain
two long-term "sessions".  Dump does most of what I need when I move from
one to the other, but if I don't chord in the project root directory to
save the dump to, I kill my other project session.
A one line change to looking at $PWD instead of $HOME makes acme much more
useful for my case, but am I missing an important other use?
