/**
 * CodeIgniter_Sniffs_Files_ClosingLocationCommentSniff.
 *
 * Ensures that a comment containing the file location exists at the end of file.
 * Only other comments and whitespaces are allowed between this comment and
 * the end of file.
 *
 * It may be all kind of comment like multi-line and inline C-style comments as
 * well as PERL-style comments. Any number of white may separate comment delimiters
 * from comment content. However, content has to be equal to template
 * "Location: <file_path_relative_to_application_root>".
 * Comparison between content and template is case-sensitive.
 *
 * There are several ways to configure the application root. In order of priority :
 *   - Configuration variable ci_application_root.
 *   - Rule property applicationRoot.
 *   - Default value '/application/'
