extra semicolons at end, like Python allows extra commas.

compiling directly from DOM!

Most expression compilation has moved to TALGenerator (exceptions for
now: attribute replacements and macro name).

allows such a module to import other modules in the same directory.

Raise error in _getobcontext if request.steps is len(0)... if someone deletes the root index_html, they will no longer get a puzzling failure if they attempt to view an object without an acquirable index_html.

Fix reference to local variable; also submitting patch to Steve Purcell.

Changed product init code so that README.txt can be any of "README.txt", "README.TXT" or "readme.txt".

we can rerun the tests and catch exceptions witha debugger.

namespace declaration.

- Only minimize empty elements when the content model is empty,
  keeping an explicit list of which elements have an empty content
  model (e.g. <img>, etc.).  This checks whether the tagname is in an
  explicit list of such elements; the check is case insensitive.

- Minimize certain attributes that are considered Boolean by HTML,
  e.g. ismap.  Again, this does a case-insensitive check whether the
  attribute name is in a list of known Boolean attributes.

Note: this should really be refactored, making HTML support a subclass
rather than a keyword argument.  Later...

- metal to do macro expansion (default on)

- tal to do TAL expansion (default on)

- html for XHTML heuristics (default off).  See
  http://www.w3.org/TR/xhtml1/#guidelines for what this should do;
  currently all it does is to suppress the XML declaration and insert
  a space before the /> in minimized elements.

Changed the TALCompiler class to generate enough code to be able to
implement the tal=0 and metal=0 options to TALInterpreter; this meant
e.g. compiling the original contents of nodes subject to replacement.
