[xwiki-users] Macros in XWiki.org dev guide

The dev guides do a fine job explaining the use of groovy and velocity code snippets. They also explain how to develop applications and plugins by creating classes. However they don't do much to explain the creation of macros; that or I'm failing to find this. I greatly prefer using macros over copy/paste coding snippets into each article. I managed to find this lovely article about creating Radeox macros in xwiki: http://hritcu.wordpress.com/2007/03/13/xwiki-plugins-tips-and-tricks/ but I'm struggling to find info on creating/adding what I believe are referred to as Velocity Macros (#macroName(var1, var2...)). I assume help has been requested on this repeatedly, but I seem to again be having poor luck in my keyword searches. Looking at trends in macro submissions, Velocity macros seem to be preferable in most cases, are they? Does each have strengths and weaknesses? I'd love to extend the online documentation, but I'm still learning. So without experience or guidance, much of what I'd write would be little more than educated guesses. Thanks, Paul D.
