% pcalinit.ps - provides the PostScript routines for pcal.c
%
% 4.0 modified by Andrew Rogers:
%
% support -w ("whole year") option - cf. printmonth_[pl], startpage
% moved all the calendar calculations to pcal.c and moonphas.c (q.v.)
%
% support -B option (leave unused boxes blank)
%
% support -O option (print "gray" numbers as outlines)
%
% revised several of the basic routines and added some others; dates,
% moons, text, Julian days are now relative to upper-left corner of box
%
% enlarged title and dates in small calendars
%
% 3.0 modified by Andrew Rogers:
%
% added xsval, ysval, xtval, ytval for scaling and translation
% as per Ed Hand
%
% added day-of-year support (-j, -J flags)
%
% 2.6 * no modifications *
%
% 2.5 modified by Joe Brownlee:
%
% made day numbers smaller, providing more room for event text
% repositioned event text and moons accordingly
% added support for variable first day of week
%
% 2.4 * no modifications *
%
% 2.3 modified by Jamie Zawinski <jwz@lucid.com>:
%
% merged in moon routines (originally by Mark Hanson)
%
% 2.2 modified by Joe Brownlee:
%
% add "notetext" to print notes in unused calendar box
%
% 2.1 modified by Mark Kantrowitz:
%
% use symbolic names instead of magic numbers throughout
% support -L, -C, -R, -n options (all new)
% print holiday text in otherwise-wasted space next to date
% use larger text for dates in large calendars
%
% 2.0 modified by Andrew W. Rogers:
%
% skip printing days of week on small calendars
% center month and year at top of calendar
% use correct algorithm for leap year calculation
% get month and day names from main program
% use table to determine color (black/gray) of weekdays and holidays
% use hanging indent to print continued text lines

X * Flags may appear in any of three places: in environment variable
X * PCAL_OPTS, on the command line, or in "opt" lines in the date file.
X * The command line is actually parsed twice: once before reading the date
X * file to get the flags needed in processing it (-e, -f, -b, -g, -D, -U, -A,
X * -E), and again after reading the date file to give the user one last
X * chance to override any of the other flags set earlier. (Note, however,
X * that the only way to turn off -J|-j [Julian dates], -M|-m [moons], -w
X * [whole year], or -O [outline "gray" dates] once selected is to use -I
X * to reinitialize all program defaults.)
X *
X * The table below supplies the following information about each flag:
X *
X * - Its name (cf. symbolic definitions above)
X *
X * - Whether or not it can take an (optional) argument
X *
X * - Which passes parse it: P_ENV (environment variable), P_CMD1
X * (first command line pass), P_OPT ("opt" lines in date file),
X * and P_CMD2 (second command line pass)
