I'm trying to write a custom action, reading other recipies and such,
trying to wrap my brain around them -- where is it documented what all
these functions do?

For example, I see in pmwiki.php that SDV does this:

  function SDV(&$v,$x) { if (!isset($v)) $v=$x; }

...but I'm not exactly sure what the reasoning is behind assigning a
variable that way.

Head hurts.  Probably just brain-freeze from the Slurpee, but you can
never be too sure when you're wrestling with code.  :-,
