emacs
'Remember' is a mode for remembering data. It uses whatever back-end is
appropriate to record and correlate the data, but its main intention is to
allow you to express as little structure as possible up front. If you later
want to express more powerful relationships between your data, or state
assumptions that were at first too implicit to be recognized, you can
'study' the data later and rearrange it. But the initial 'just remember
this' impulse should be as close to simply throwing the data at Emacs as
possible.
