### Module setup

BEGIN {

    use Exporter ();

    our ($VERSION, @ISA, @EXPORT, @EXPORT_OK, %EXPORT_TAGS);

    # Version checking

    $VERSION = '0.1.5';

    @ISA = qw(Exporter);

    @EXPORT = qw(

    );

    @EXPORT_OK = qw(

        &Move_File

    );

    %EXPORT_TAGS = (

        'functions' => [qw(&Move_File)],

        'vars' => [qw()],

    );

}

### Exported package globals

# None

### Non-exported package globals

# Thread-safe? What's that? Package global error value. We don't export

# this directly, because it would conflict with other modules.

our($Error);

### File lexicals

# None

### Constant functions

# None

### Meaningful functions

# Move_File($orig, $new, $mode)

#

# Move an file from $orig to $new by copying, and set the file mode

# of the new file according to the variables given.

#

# Returns 1 if successful, 0 if not (and sets $Error)
