Call with no arguments to filter WML on stdin to reindented WML on
stdout. If arguments are specified, they are taken to be files to be
re-indented in place; interrupting will be safe as each reindenting
will be done to a copy that is atomically renamed when it's done. This
code never modifies anything but leading whitespace on lines.
re-indented in place; a directory name causes reindenting on all WML
beneath it.

The indent unit is four spaces. Absence of an option to change this is
deliberate; the purpose of this tool is to *prevent* style wars, not encourage

Note: This does not include a parser. It will produce bad results on WML

of a multiline literal will also confuse it. You will receive warnings
