=head2 Prerequisites

The only system dependent feature that DBD::File uses, is the C<flock()>
function. Thus the module should run (in theory) on any system with
a working C<flock()>, in particular on all Unix machines and on Windows
NT. Under Windows 95 and MacOS the use of C<flock()> is disabled, thus
the module should still be usable,

Unlike other DBI drivers, you don't need an external SQL engine
or a running server. All you need are the following Perl modules,
available from any CPAN mirror.

=head2 SQL

The level of SQL support available depends on the version of
SQL::Statement installed.
Any version will support *basic*
CREATE, INSERT, DELETE, UPDATE, and SELECT statements.
Only versions of SQL::Statement 1.0 and above support additional
features such as table joins, string functions, etc.
See the documentation of the latest version of SQL::Statement for details.

=head1 INCOMPATIBILITIES

not known

=head1 BUGS AND LIMITATIONS

The module is using flock() internally. However, this function is not
available on platforms. Using flock() is disabled on MacOS and Windows
95: There's no locking at all (perhaps not so important on these
operating systems, as they are for single users anyways).
