=item _quote_args

Command-line arguments (but not the command itself) must be quoted
to ensure case preservation.

=item find_perl_interpreter

On VMS, $^X returns the fully qualified absolute path including version
number.  It's logically impossible to improve on it for getting the perl
we're currently running, and attempting to manipulate it is usually
lossy.

    return VMS::Filespec::vmsify($^X);

=item localize_file_path

Convert the file path to the local syntax

=cut

Convert the directory path to the local syntax

=cut

  my ($self, $path) = @_;

=item ACTION_clean

The home-grown glob() expands a bit too aggressively when given a bare name,
so default in a zero-length extension.

=cut
