/**
 * Replaces tokens in the original input with the contents of a file.
 * The file to be used is controlled by the name of the token which
 * corresponds to the basename of the file to be used together with
 * the optional pre and postfix strings that is possible to set.
 *
 * By default all HTML entities in the file is replaced by the
 * corresponding HTML entities. This behaviour can be controlled by
 * the "translatehtml" parameter.
 *
 * Supported parameters are:
 *  <pre>
 *  prefix         string Text to be prefixed to token before using as filename
 *  postfix        string Text to be prefixed to token before using as filename
 *  dir            string The directory where the files should be read from
 *  translatehtml  bool   If we should translate all HTML entities in the file.
 * </pre>
 * Example:
 *
 * <pre><filterreader classname="phing.filters.ReplaceTokensWithFile">
 *   <param name="dir" value="examples/" />
 *   <param name="postfix" value=".php" />
