[elephant-devel] Re: export #:db-error ?

[Ian Eslick]

db-error is a general condition which says there was an internal  
error in the db (something that is not likely the fault of the  
user).  I've started adding other conditions that are problem- 
specific and refer to things the user has done in error.  As part of  
cleanup, they should inherit from a common source so you can  
inhibit / handle all elephant conditions as necessary.  Please add  
comments to an existing ticket or a new tickets to describe your  
thoughts about what should be done here.
