* deals with the holiday file. A yacc parser is used to parse the file.
* All the holidays of the specified year are calculated at once and stored
* in two arrays that have one entry for each day of the year. The day
* drawing routines just use the julian date to index into these arrays.
* There are two arrays because holidays can be printed either on a full
* line under the day number, or as a small line to the right of the day
* number. It's convenient to have both.
*
* parse_holidays(year, force) read the holiday file and evaluate
* all the holiday definitions for
* <year>. Sets holiday and sm_holiday
* arrays. If force is set, re-eval even
* if year is the same as last time.
*
* Taken from plan by Thomas Driemeyer <thomas@bitrot.de>
