-/**
- * A reader for Hijrah Deviation files.
- * <p>
- * For each Hijrah calendar a deviation file is used
- * to modify the initial Hijrah calendar by changing the length of
- * individual months.
- * <p>
- * The default location of the deviation files is
- * {@code <java.home> + FILE_SEP + "lib"}.
- * The deviation files are named {@code "hijrah_" + ID}.
- * <p>
- * The deviation file for a calendar can be overridden by defining the
- * property {@code java.time.calendar.HijrahChrono.File.hijrah_<ID>}
- * with the full pathname of the deviation file.
- * <p>
- * The deviation file is read line by line:
- * <ul>
- * <li>The "#" character begins a comment -
- * all characters including and after the "#" on the line are ignored</li>
- * <li>Valid lines contain two fields, separated by whitespace, whitespace
- * is otherwise ignored.</li>
- * <li>The first field is a LocalDate using the format "MMM-dd-yyyy";
- * The LocalDate must be converted to a HijrahDate using
- * the {@code islamic} calendar.</li>
- * <li>The second field is the offset, +2, +1, -1, -2 as parsed
- * by Integer.valueOf to modify the length of the Hijrah month.</li>
- * <li>Empty lines are ignore.</li>
- * <li>Exceptions are throw for invalid formatted dates and offset,
- * and other I/O errors on the file.
- * </ul>
- * <p>Example:</p>
- * <pre># Deviation data for islamicc calendar
- * Mar-23-2012 -1
- * Apr-22-2012 +1
- * May-21-2012 -1
- * Dec-14-2012 +1
- * </pre>
