amnesia wraps everything exposed by mnesia, from fragments to fragment hash, access and backup behaviors.

It provides a simplified table and database definition with some macros and allows you to use the nice Enum functions on tables by implementing the Enum.Iterator protocol.

Everything is documented and specced, even the unspecced and undocumented parts of mnesia that have been wrapped.

The documentation often refers to mnesia functions, I strongly suggest you read mnesia's documentation too, since it has a lot of valuable information.
