I meant the concept: the user sets some variable, and that causes
debug information to be collected in some buffer.  The variable could
be a boolean, or it could allow specifying different levels of debug
info to collect.  See tramp-verbose for an example.  (I'm sure Michael
can describe these Tramp facilities in more detail if needed.)

Thanks.
