Well, if it only has to work with the current databases...

Flat file should be fairly easy to recognize ('file' should be able to
do this for you), since it is just plain text.

skiplist should start with the following magic string:
"\241\002\213\015skiplist file\0\0\0"

Berkeley DB should be anything else.
