Tag sets

Tag definitions can be grouped by setting up a global hash named %sets.

    %sets=(
           pointto => [qw(EMPHASIZE COLORIZE)],
          );

When using the definition module, this allows to activate the tags \EMPHASIZE and \COLORIZE together:

    # declare all the tags to recognize
  
    use PerlPoint::Tags::New qw(:pointto);

The syntax is obviously borrowed from Perls usual import mechanism.

Tag sets can overlap:

    %sets=(
           pointto => [qw(EMPHASIZE COLORIZE)],
           set2    => [qw(COLORIZE FONTIFY)],
          );

And of course they can be nested:

    %sets=(
           pointto => [qw(EMPHASIZE COLORIZE)],
           all     => [(':pointto', qw(FONTIFY))],
          );
