    org.apache.commons.vfs.FileContent content = file.getContent();
    FileContentInfo info = content.getContentInfo();
    log.debug("Content type: {}", info.getContentType());
    log.debug("Content encoding: {}", info.getContentEncoding());

    //
    // TODO: Only cat files which we think are text, or warn if its not, allow flag to force
    //

    log.debug("Displaying file: {}", file.getName());
