=head1 DESCRIPTION
=head2 load_files( )
- Config::Any->load_files({files => \@files]});
- Config::Any->load_files({files => \@files, filter => \&filter});
- Config::Any->load_files({files => \@files, use_ext => 1});
+ Config::Any->load_files( { files => \@files } );
+ Config::Any->load_files( { files => \@files, filter => \&filter } );
+ Config::Any->load_files( { files => \@files, use_ext => 1 } );
C<load_files()> attempts to load configuration from the list of files passed in
the C<files> parameter, if the file exists.
of a non-standard file extension while forcing it to be offered to a particular parser.
It is not compatible with 'use_ext'.
+You can supply a C<driver_args> hashref to pass special options to a particular
+parser object. Example:
+
+ Config::Any->load_files( { files => \@files, driver_args => {
+ General => { -LowerCaseNames => 1 }
+ } )
