  @attr2 = ( $attr => $value );
  $attr{$attr} = $value;
  Decision::Depends::Configure( \%attr, $attr => $value, \@attr );

A dependency file is not required if there are no signature or
variable dependencies.  In that case, if no attributes need be set,
this routine need not be called at all. 

The available attributes are 

=over 8

=item File

The name of a file which contains (or will contain) dependency
information.  In general this should be an absolute path, unless
the directory will not be changed.

=item Force

If set to a non-zero value, all dependencies will be out-of-date,
forcing execution of all actions.

=item Pretend

If set to a non-zero value, B<Decision::Depends> will simulate the actions
to track what might happen.

=item Verbose

If set to a non-zero value, B<Decision::Depends> will be somewhat verbose.

=back

For example,

  Decision::Depends::Configure( { File => $depfile Pretend => 1, Verbose => 1 } );


=back


=head1 EXPORT

The following routines are exported into the caller's namespace
B<if_dep>, B<action>, B<test_dep>.

=head1 NOTES

This module was heavily influenced by the ideas in the B<cons> software
construction tool.

The C<{targdep}> and C<{actions}> clauses to B<if_dep> are actually
anonymous subroutines.  Any subroutine reference will do in their
stead

  if_dep \&targdep 
    action \&actions;

=head1 BUGS AND LIMITATIONS

=for author to fill in:
    A list of known problems with the module, together with some
    indication Whether they are likely to be fixed in an upcoming
    release. Also a list of restrictions on the features the module
    does provide: data types that cannot be handled, performance issues
    and the circumstances in which they may arise, practical
    limitations on the size of data sets, special cases that are not
    (yet) handled, etc.

No bugs have been reported.
