=setsize(20px).
To facilitate resizing relative to a base size, pll contains commands
=setbasesize, =tiny, =small,
=normal, =large, =huge and
=setfactor.
=setbasesize defines the size used when issuing
=normal. Giving command =tiny,
=small, =large or =huge sets a size
relative to the base size. The factors used are defined by
=setfactor, taking two arguments: A string (``tiny'',
``small'', ``large'' or ``huge'') and a factor.
