+/**
+ * PHP version of the callback template processor
+ * This is currently used as a test rig and is likely to be used for
+ * compatibility purposes later, where the C++ extension is not available.
+ *
+ * Template syntax
+ * ---------------
+ *
+ * There are two modes: text mode and function mode. The brace characters "{"
+ * and "}" are the only reserved characters. Either one of them will switch from
+ * text mode to function mode wherever they appear, no exceptions.
+ *
+ * In text mode, all characters are passed through to the output. In function
+ * mode, text is split into tokens, delimited either by whitespace or by
+ * matching pairs of braces. The first token is taken to be a function name. The
+ * other tokens are first processed in function mode themselves, then they are
+ * passed to the named function as parameters. The return value of the function
+ * is passed through to the output.
+ *
+ * Example:
+ * {escape {"hello"}}
+ *
+ * First brace switches to function mode. The function name is escape, the first
+ * and only parameter is {"hello"}. This parameter is executed. The braces around
+ * the parameter cause the parser to switch to text mode, thus the string "hello",
+ * including the quotes, is passed back and used as an argument to the escape
+ * function.
+ *
+ * Example:
+ * {if title {<h1>{title}</h1>}}
+ *
+ * The function name is "if". The first parameter is the result of calling the
+ * function "title". The second parameter is a level 1 HTML heading containing
+ * the result of the function "title". "if" is a built-in function which will
+ * return the second parameter only if the first is non-blank, so the effect of
+ * this is to return a heading element only if a title exists.
+ *
+ * As a shortcut for generation of HTML attributes, if a function mode segment is
+ * surrounded by double quotes, quote characters in the return value will be
+ * escaped. This only applies if the quote character immediately precedes the
+ * opening brace, and immediately follows the closing brace, with no whitespace.
+ *
+ * User callback functions are defined by passing a function object to the
+ * template processor. Function names appearing in the text are first checked
+ * against built-in function names, then against the method names in the function
+ * object. The function object forms a sandbox for execution of the template, so
+ * security-conscious users may wish to avoid including functions that allow
+ * arbitrary filesystem access or code execution.
+ *
+ * The callback function will receive its parameters as strings. If the
+ * result of the function depends only on the arguments, and certain things
+ * understood to be "static", such as the source code, then the callback function
+ * should return a string. If the result depends on other things, then the function
+ * should return an object:
+ *
+ * return new TplValue( $text, $deps );
+ *
+ * where $deps is an array of string tokens, each one naming a dependency. As a
+ * shortcut, if there is only one dependency, $deps may be a string.
