|
|
%%% How to use:
|
|
%%% A table can be converted from Mnesia to an ODBC database by calling
|
|
%%% one of the API function with the following parameters:
|
|
%%% - Server is the server domain you want to convert
|
|
%%% - Output can be either odbc to export to the configured relational
|
|
%%% database or "Filename" to export to text file.
