Skills are non-magical abilities, ranging from mundane tasks to
heroic feats.  Using most skills requires endurance points 
(see: help using skills) although some are passive or automatic 
and exact no cost for being in effect.
    
Your training in your skills (see: show skills) varies depending 
on how many times you have trained (see: help training), what 
skill bonuses you have earned (from levels and other sources, 
such as equipment), environmental effects (being underwater 
gives most races a penalty), and armor bulk (see: help bulk).
    
To learn the description of any skill, use the 'help skill '
command.  For example, 'help skill fire building' is a common skill,
and 'help skill attack' is a common auto skill.
