@section Building the @ezfio database
An @ezfio database is a directory which contains all the needed input/output data
needed by the code. 

@subsection Using the provided wrapper

The output file from Molpro, @gamess or Gaussian has to be transformed
into an @ezfio database in order to be used by @exe. This step is realized by
calling the @command{to_ezfio.exe} command, followed by the name of the
file containing the wave function:
@example
to_ezfio.exe test.out
@end example
An @ezfio database is then produced, named @file{test.out.ezfio}.


@subsection Using your own code
Refer to the @ezfio web site@footnote{http://ezfio.sourceforge.net}
to learn how to use the @ezfio @acronym{API} to collect your data into an
@ezfio database.  The @ezfio definition file is the @file{eplf.config} file,
located at the root of the EPLF package.
