Version 3.0 of SimpleTAL is now available! The major new feature in this release is support for METAL. METAL is an HTML/XML macro language that augments TAL. It allows a sub-tree of a document to be associated with a macro name, and additionally for customisation points (slots) within that sub-tree to be defined. Once a macro has been defined in this way you can then graft the sub-tree into a (potentially different) document and optionally customise the macro by passing in another sub-tree (i.e. filling the slot).

While METAL is pretty nifty, it’s also very hard to explain without an example. So if you are unsure what it is and why you might want to use it, take a look at this example.
