...tem -- usually already true on MacOS and Linux, but takes an extra step on Windows, i.e. see http://strawberryperl.com/). There are various caveats, and alternatives, listed on the R wiki page.

...emplates can match a node, the one with the more specific match expression wins. If more than one matching template with the same specificity exist, the one declared last wins. You can concentrate more on developing templates and need less time to do "plumbing". Your programs will become more power...

...r-side language required, and most of all very EASY to understand. It's a win-win. The one thing it does have limits on, though, is strict formatting of columns. If formatting and colors are absolute dealbreakers, the only 100% reliable, cross browser method I've found is to use a server-side lan...

Some lead to a win by your opponent, when you reach such an ending, you must back up, or backtrack, to a previous node and try a different path. In this way you explore the tree until you find a path with a successful co...
