input-file-spec[,...]

    A comma separated list of one or more text files containing the
    entries to be placed into the database. Each line of the text
    files must correspond to a single entry. All specified input
    files are read and merged into a single output database.

 output-database-spec

    The name of the database file to write the database to. This may
    be a new or existing database. If the /NOFAST_LOAD qualifier is
    specified and the database already exists no new database will be
    created; records will simply be added to the existing database.
