We had a version of autosave at LBNL that looked at characters
stuck in the end of the record description file at boot time, using
the static library, to find out what records should be saved.
Yes, one can use the DESC field to add additional information,
like in this case instructions for autosave.
I've also used it to provide additional parameters
to an analog input device module.
But that's of course somewhat of a hack.
I think there is now a better way to do this,
because the Database files support adding non-field
meta information to record instances,
beyond just the values of record fields.
I don't remember the exact syntax, even though Andrew
has pointed it out several times.
I think it's called "info node",
and could be used to add parameters for
autosave, archiving, ... anything to record instances.
Of course you would then also have to write the
tool that reads those info node values
and creates the autosave, archive, ... config files.
