pcal - generate PostScript (or HTML) calendars
pcal [-e|-f cal] [-o file] [-l | -p] [-P [letter | legal | a4 | tabloid]] [-j | -J] [-m | -M] [-g weekday[-weekday]|all|holiday] [-O weekday[-weekday]|all|holiday] [-G weekday[-weekday]|all|holiday] [-b weekday[-weekday]|all|holiday] [-s [day_numerics_color][/empty_day_box_fill_color]] [-F day] [-A|-E] [-X xtrans] [-Y ytrans] [-x xscale] [-y yscale] [-t [title_font][/size]] [-d [day_font][/size]] [-n [text_font][/size]] [-L footer_str] [-C footer_str] [-R footer_str] [-N notes_str] [-D symbol] [-U symbol] [-B] [-# n] [-S | -k | -K] [-w] [-I] [-c | -H] [-q] [-z time_zone] [-h | -u | -v] [-a output_language] [-r [mapping] [-T [B|I|R]] [-W [left|center|right]] [month] [year] [nmonths]
Pcal generates PostScript to produce landscape or portrait calendars for any month and year. The arguments month, year, and nmonths, if provided, should be numeric. The month value should be in the range 1 - 12, and the year value should be specified as 1 or 2 digits (in which case it will be interpreted as that year in the current century) or as the full 4-digit year. If no numeric arguments are provided, the calendar for the current month and year will be generated.
If one numeric argument is provided, it is interpreted as the year value, and calendars for the entire year will be generated. Otherwise, nmonths months, starting with month and year, will be generated.
For whole-year calendars (i.e. when the -w option is given), the command line arguments are interpreted somewhat differently. By default, all months in the current year are printed, starting with January. If the month argument alone is given, it is expected to be the desired year to print, and prints all of the months in the given year. If both month and year are given, then 12 consecutive months are printed starting at the given month and year. If the month, year, and nmonths arguments are all present, printing begins with the given month and year and nmonths months are printed, rounded up to the nearest multiple of 12.
By default, pcal simply prints an empty calendar. Its real power is in its ability to place ``events'' (and, for monthly-format PostScript calendars, Encapsulated PostScript images [e.g. photos and icons]) in appropriate days on the (PostScript or HTML) calendar, thus allowing the user to create personalized calendars. This is achieved through the use of the ``date file'', also known as the ``configuration file''.
The default date/configuration file is expected to be named .calendar (pcal.dat under MS-DOS), or calendar for compatibility with older versions. Pcal will look in several places for such a file. First, if the environment variable PCAL_DIR is defined, pcal searches the directory indicated by that variable. Next, pcal searches the user's home directory (as specified by the HOME environment variable). If neither PCAL_DIR nor HOME is defined, pcal searches the current directory instead. Finally, if enabled (via the `SEARCH_PCAL_DIR' flag) when pcal was built, the directory where the pcal executable resides will be checked. (This final search of the executable directory has been disabled in the version shipped with Debian.) If no date file is found, an empty calendar is printed; no error is generated.
Alternatively, the name of the date file (and, optionally, the path where it can be found) can be specified using the -f command-line option. See the OPTIONS section for more details.
Every pcal distribution comes with an 'examples' directory. The `pcal-cfg.txt' file that is located there contains a myriad of examples of settings that can be used in your own configuration file. Please check it out for lots of useful ideas. Furthermore, that directory contains several language/country-specific examples (including holiday and other event definitions) in various `calendar_xx.txt' files, where `xx' represents the 2-letter language code (e.g. 'calendar_de.txt' is the German example file).
If a date file is found, it will be searched for lines with leading dates matching the requested month and year.
Any text following the dates found will be printed on the calendar under the appropriate day of the month. Encapsulated PostScript (EPS) images are handled similarly as described in a later subsection.
troff-style escape sequences \fB, \fI, \fP, and \fR may be used to set the font style to Bold, Italic, the previous font style, or Roman respectively. For those more familiar with HTML, <B>, <I>, </B>, and </I> may be used instead to enable/disable Bold or Italic font styles. The font style is reset to Roman after each line break.
Using the `include' pre-processor directive (described in the section entitled `Pre-Processor Functionality', below), other configuration files can be processed from within an existing configuration file. That is, you can `nest' configuration files as needed.
Dates (essentially `events') in the configuration files may be expressed in any of several formats:
Where:
If the -A option (American date formats, the default) is given:
If the -E option (European date formats) is given:
The ``Notes'' box (see below) uses the first of the current month as the default date. All footer strings use the first of the current month in single-month mode and the first of the starting month in whole-year mode.
Examples:
last Monday in May* Memorial Day Holiday all Fridays in Oct Status Meeting, 11 AM first workday in all %-B progress report due all Fri in all \fBTime card due,\fP 3 PM all Monday in all Fiscal week %0W -2nd workday in all Schedule for %+B due %+2D 2nd full_moon in all Blue Moon Fri on_or_before all 15 Pay Day even Fridays in year Pay Day 183rd day of year Mid-year (%l days left) Tue after first Mon in Nov Election Day (USA) 4th Thu in Nov* Thanksgiving Fri after 4th Thu in Nov* Day after Thanksgiving workday nearest 12/25* Holiday 12/25/04* Christmas # American 25.12.04* Christmas # European 25. 12.* Christmas # European Dec 25* Christmas # American 25 Dec* Christmas # European 25. Dec* Christmas # European Fri on all 13 Avoid black cats! # 'Friday the 13th'
Any non-numeric character may separate numeric dates. Holidays may be flagged by following the date immediately with `*' as in the examples above; this will cause the date numerics to be printed in the color specified by the -s option (default = gray) and will cause the associated text (on monthly-format calendars) to be placed adjacent to the numeric date in the day box rather than below the numeric date (as is done for all non-holiday events). ``Each'' and ``every'' are accepted as synonyms for ``all'', and any word may be used in place of ``in''. The abbreviations ``oob'' and ``ooa'' may be used in place of the keywords ``on_or_before'' and ``on_or_after'', respectively. ``Nearest'' attempts to match the specified date; if that fails, it tries the day after, then the day before, then two days after, two days before, and so forth until a match occurs.
Wildcard day names are also provided. The keyword ``weekday'' applies to any days which are normally printed in "logical black" - the predominant day color - on the calendar. The keyword ``workday'' is the same, but does not include any holidays. The keyword ``holiday'' includes only those days flagged as holidays. The keywords ``nonweekday'', ``nonworkday'', and ``nonholiday'' are also recognized as negations of the above. See the CAVEATS below for important notes on using these keywords. Moon phases may also appear as wildcards; ``nm'' is accepted as a synonym for ``new_moon'', ``1q'' and ``fq'' for ``first_quarter'', ``fm'' for ``full_moon'', ``3q'' for ``third_quarter'', and ``lq'' for ``last_quarter''.
Ordinal day numbers may be used to specify dates, either relative to the month or to the year. Either words or numeric abbreviations may be used for ``first'' through ``fifth''; higher numbers must be given using the numeric equivalent (e.g. 100th). Negative ordinal numbers may even be used. For example, ``-2nd'' means ``next to last''.
``Odd'' and ``even'' do not refer to the actual date; instead, ``odd'' means ``alternate, starting with the first'', and ``even'' means ``alternate, starting with the second''. Thus, ``odd Fridays in March'' refers to the first, third, and (if present) fifth Fridays in March — not to those Fridays falling on odd dates.
``All'' refers to each individual month; ``year'' refers to the year as an entity. Thus ``odd Fridays in all'' refers to the first, third, and fifth Friday of each month, while ``odd Fridays in year'' refers to the first Friday of January and every other Friday thereafter.
``Nearest'', ``nearest_before'', and ``nearest_after'' refer to the nearest weekday or wildcard day with respect to the specified date. ``Nearest_before'' and ``nearest_after'' allow the user to specify how pcal is to disambiguate between two dates that are equally near: e.g., ``nonweekday nearest_before [Wed.] 9/25/96'' refers to Sunday, 9/22 while ``nonweekday nearest_after 9/25/96'' refers to Saturday, 9/28. (Note that ``nearest_before'' and ``nearest_after'' are equivalent to ``nearest'' when no such ambiguity exists: e.g., ``nonweekday nearest_before [Thu.] 9/26/96'' refers to Saturday, 9/28.)
Text in the date file may use C-like escape sequences (i.e. a `\' followed by a character, 1 - 3 octal digits, or `x' followed by 1 - 2 hexadecimal digits). Escaped whitespace (including newline ) and the standard ANSI character escapes (`\a', `\b', `\f', `\n', `\r', `\t', `\v') are all replaced by a single blank.
The HTML special characters `<' `>' `"' `&' ` ' and `&#NNN;' (NNN = any three decimal digits) are also supported. These will be propagated intact (be sure to escape the `#' in `&#NNN;') if the output is specified as HTML (see the -H flag); otherwise they will be converted to their ASCII equivalents. This allows a common date file to be used regardless of whether the desired output format is HTML, PostScript, or Un*x calendar(1) (see the -c flag) input.
Lines in the configuration file consisting of year #### (where #### is a numeric year) can be used to set the year for following entries. This assumes that the following entries do not contain a year; any date entries containing year information will set the remembered year to that year.
Lines in the configuration file consisting of year all (or, alternatively, year *) direct pcal to wildcard following entries against every applicable year. This assumes that the following entries do not contain a year; any date entries containing year information (or an explicit year #### entry) will set the remembered year to that year.
Lines in the configuration file consisting of opt <options> can be used to override the defaults for any command-line options except -c, -e, -f, -h, -H, -u, -v, -D, and -U. Any options specified in this manner are, in turn, overridden by those specified explicitly on the command line.
Lines in the configuration file consisting of note{/<number>} <month> can be used to place notes regarding the entire month in one of the unused blocks of the calendar. The <month> indicator may be either a number 1 through 12 or an alphabetic month name as described above; ``note all'' will place the associated text in the notes block for each month in the current year. <number> is an optional positive or negative number specifying the empty box where the associated text is to be placed. If positive, pcal counts forward from the first empty box; if negative, pcal counts backward from the last empty box. Thus, ``note/1'' places the associated text in the first empty box; note/-3 in the third-to-last. The default is -1 if no <number> is given (last empty box, immediately preceding the small calendars on the bottom row; cf. -S, -k, and -K, below). You can place several notes in the same box. You can also use more than 1 box for the various monthly notes.
Lines in the configuration file consisting of input-language XX (where XX is the 2-letter specification for any of the supported languages) can be used to set the language used for interpretation of the month names and day-of-week names for the remaining event entries. This option may be specified more than once, as needed, if the language used to describe events changes within the file. For backwards compatibility, the default value for `input language' if this directive is never used is 'en' (English). Note that this directive is distinct from the specification of 'output language' as accomplished with the -a option.
Comments are supported in the configuration file. Any characters following a `#' character are ignored, through the end of that line, unless the `#' character is escaped by `\'.
By prepending the `delete' keyword to an event specification, one or more events may be deleted from a set of previously-specified events.
For example, the following lines might appear in the date file:
all Friday in all Poker game delete first Friday in all Poker game
This results in an event labeled `Poker game' on every Friday except the first Friday of the month. If you delete an entry which is marked as a holiday, the `holiday' flag for that day will be recalculated. Any `delete' entries which don't match any pre-existing entries are silently ignored.
Pcal allows format specifiers in both the event text and footer strings (see the -L, -C, -R, and -N options below). Each format specifier will be replaced by a corresponding string as outlined in the following table:
%a abbreviated weekday %A full weekday %b abbreviated month name %B full month name %d day of month (1-31) %j day of year (1-366) %l days left in year (0-365) %m month (1-12) %U week number (0-53) %W week number (0-53) %u week number (1-54) %w week number (1-54) %y year w/o century (00-99) %Y year w/century %% `%' character %o print number as ordinal %0 print number with leading zeroes %+ use following month or year %- use previous month or year %{+N}[DWMY] adjust date by +N days/weeks/months/years %{-N}[DWMY] adjust date by -N days/weeks/months/years
Most of these are derived from the ANSI C strftime() function, but the %[louwMD] and %[o0+-] format specifiers are specific to pcal.
The %u specifier considers the week containing 1/1 (Jan 1st) as week 1 and the following logical Sunday (the first day of the week as printed; cf. the -F option below) as the start of week 2; %U considers the first logical Sunday as the first day of week 1. %w and %W behave like %u and %U respectively, but use the first logical Monday instead. Note that %w has a different meaning from strftime().
The %o format specifier prints a number as an ordinal, with the appropriate suffix (``st'', ``nd'', ``rd'', or ``th'' in English) appended. For example, %od prints the day of the month as ``1st'', ``2nd'', ``3rd'', etc.
Unlike strftime(), pcal defaults to printing numbers (except %y) without leading zeroes. If leading zeroes are desired, the `0' prefix may be used. For example, %0j prints the first day of year as ``001''.
The %+ and %- format specifiers direct pcal to substitute the following/previous month/year in the following [bBmyY] specifier. For example, %+B prints the name of the next month.
The %{[+-]N}[DWMY] format specifiers do not print anything, but instead adjust the working date by ± Ndays (D), weeks (W), months (M), or years (Y). Subsequent format specifiers use the adjusted date instead of the current date. For example, %+1M %B %Y adjusts the date forward by one month and then prints the resulting month and year (``January 1992'' in December, 1991); %-2W %b %d adjusts the date backward by two weeks and prints the resulting month and day (``Jul 26'' on August 9).
Such date adjustments are normally cumulative; for example, %+1Y%-1D adjusts the date forward by one year and then backward by one day. If %D or %M is specified alone (or if N is zero), pcal restores the original date. Note that %M has a different meaning to the strftime() function.
Here's a common, useful example of an event entry for the pcal date file which combines the ability to adjust working dates and the ability to display ordinals. This particular example is used to display text on the birthday of a person born in 1991:
May 10 Eric's %-1991Y%oY Birthday
That entry would result in the following text being displayed on May 10, 2005:
Eric's 14th Birthday
For monthly PostScript calendars only, pcal supports the embedding of one or more EPS images (photos, icons, etc) into any given day of the month. (EPS image specifications in the pcal date file are ignored for yearly PostScript calendars and for all HTML calendars.)
In order to associate an image with a given event, you must add one or more entries to the date file. The event date is specified exactly as described previously for simple event text specification lines. However, instead of specifying the text associated with the event, you instead specify the EPS image filename and some additional parameters in the following format:
image:<EPS-image-filename> <x-scale> <y-scale> <x-delta> <y-delta>
Where:
Here's an example of a line from the date file that associates an EPS image with an event:
4th Thu in Nov* Thanksgiving 4th Thu in Nov* image:/eps-path/turkey.eps 1.0 1.0 0 0
You can place as many images as you want on a single day of the month by specifying repeated lines in the date file. For example, these lines put icons of George Washington and Abraham Lincoln on the day of the U.S. ``Presidents' Day'' holiday, along with the event text:
3rd Monday in Feb* Presidents' Day 3rd Monday in Feb* image:/eps-path/washington.eps 0.08 0.08 8 0 3rd Monday in Feb* image:/eps-path/lincoln.eps 0.22 0.22 48 0
Note that the icon for Lincoln is shifted to the right by 48 typographic points so as not to overlay the first icon.
The pcal releases come with a single EPS sample file ('eps/recycle.eps') of the ubiquitous 'recycle' icon (3 green arrows in a triangular shape). Such an image might be used with configuration file settings like this:
second Sat in all RECYCLE! second Sat in all image:/eps-path/recycle.eps 0.039 0.039 34 -9
In cases where you're displaying non-holiday event text (e.g. someone's birthday) and an EPS image, you'll often need to use a negative `Y-delta' value on the EPS image specification line, in order to shift the image down so that it doesn't cover the event text, which appears just below the day's numerics for non-holiday events. (Text for holiday events appears higher up, to the right of the day's numerics, so there's usually no collision with the EPS image.)
Note: Unfortunately, most EPS images cannot be used directly by pcal.
Depending on the EPS image used and how it was created, you may have to remove or comment out some or all of the PostScript `translate' commands, in order to avoid the use of illogical X-delta and Y-delta values when specifying the EPS image in your pcal date file. Most programs that generate EPS output (either directly or via conversion from some other graphic format) seem to have these `translate' commands relatively early in the EPS file.
It may take some experimentation to get it just right. Preview the pcal output using a PostScript viewer as you tweak the PostScript commands in the EPS image file and/or the event entry in the pcal date file.
Note: Depending upon what application you use to preview PostScript content, the monthly calendars may not show any embedded EPS images. Here's a rundown of some popular PostScript-viewing applications and whether they correctly display the embedded EPS images:
For converting non-EPS images (e.g. photos) to EPS format, one can use the graphical GNU Image Manipulation Program, a.k.a. `The GIMP':
http://www.gimp.org
For icons/images in WMF format (which are popular in various 3rd-party, legacy-OS, commercial calendar programs), the `libwmf'/`wmf2eps' library/utility is useful for generating pcal-capable EPS images. It can be found at this site:
http://wvware.sourceforge.net/libwmf.html
For icons/images in SVG format, the ImageMagick `convert' utility is sometimes useful for generating pcal-capable EPS images. This suite of utilities (which includes other useful ImageMagick utilities like `display' and `identify') may already be available on your Linux distribution. If not, it can be found at this site:
http://www.imagemagick.org
For cases where ImageMagick's `convert' utility fails to properly convert SVG-format images to EPS format, you can try the method of converting the SVG image into an intermediate format (e.g. PNG) using the `rsvg' utility. This utility may already be available on your Linux distribution. If not, it can be found at this site:
http://librsvg.sourceforge.net/
From the PNG format, the image can often then be successfully converted to EPS format, using the above-mentioned ImageMagick `convert' utility.
The Open Clip Art Library is a good source of freely-usable images (many of which are in SVG format) for decorating your events:
http://www.openclipart.org
Note: The EPS image content is not generated in the PostScript output -- only a reference to the EPS image filename is generated. From a practical standpoint, this means that normally you'll need to print/preview the PostScript output of pcal from the same computer/setup as that which was used to run pcal in the first place. If you want to generate a calendar with embedded EPS images that will later be printed/viewed on another machine which does not have access to those EPS images, you'll need to run the output through a pre-processor which will put the EPS image content into the PostScript output file. For example, assuming your initial calendar output was generated to a file named `pcal.ps', on most GNU/Linux systems you could run this command, which uses the popular `Ghostscript' interpreter:
gs -r300x300 -dBATCH -dNOPAUSE -sDEVICE=pswrite -sOutputFile=out.ps pcal.ps
This would generate a PostScript file named `out.ps', at 300x300 dpi resolution, which has the actual EPS image content embedded within, allowing you to transport the `out.ps' file to another computer for viewing/printing. Of course, the new file is substantially larger, but it's portable. Furthermore, the EPS images will be viewable even in PostScript-viewing applications (see above) which don't properly support the display of embedded (by filename only) EPS images.
Pcal supports rudimentary cpp-like functionality in the date file, allowing the following constructs:
Note that these are not preceded by `#' as they are in C.
Symbol names defined using these keywords (or via the -D option) are case-insensitive. It is not an error to undef an undefined symbol, nor to define a previously-defined one.
A symbol can be defined with just a name (e.g. ``define MY_SYM'') or it can take on a value (e.g. ``define MY_SYM SOME_VALUE''). Use of symbol values is convenient for defining a starting date then using that symbol to reference that starting date in one or more events. For example, these definitions in the date file might be useful:
define semester_start 8/23 # Beginning of semester semester_start Class Start 7th day after semester_start 1st Quiz 14th day after semester_start 2nd Quiz undef semester_start
Be aware that the substitution of symbol values for symbol names is not robust, so it's wise to use a symbol name that's unlikely to occur in any of your other event text. In other words, if you defined the `semester_start' symbol in the example above as merely `start', then you'd get the undesired effect of having the text `Class 8/23' in your calendar on that day instead of `Class Start'! The use of `undef semester_start' in the above example is optional and is really only useful to prevent any unwanted symbol substitutions later on, which probably won't happen unless you poorly choose your symbol name to begin with.
An ifdef alone is always false; an ifndef alone is always true. if is accepted as a synonym for ifdef.
The name of the file in the include directive may optionally be surrounded by either "" or <>, both of which are ignored. If the name is not an absolute path, it is taken to be relative to the directory where the file containing the directive is located. If the string "%y" appears in the file name, it is replaced by the last two digits of the current year or, if "year all" is in effect, is expanded to all applicable years. Pcal is smart enough to translate ~/ to the user's home directory.
Pcal normally terminates immediately if the file specified in an include directive does not exist. An alternate form of the directive, include?, directs pcal to continue silently if the file does not exist or cannot be opened.
In addition to pre-processing keywords, pcal also accepts boolean expressions in if{{n}def} and elif directives. These expressions consist of symbol names joined by the boolean operators !, &, ^, and |, in order of precedence, high to low. Parentheses may be used to alter the precedence. The synonyms && and || are accepted for & and |. A symbol name evaluates to true if currently defined, false if not; thus:
ifdef A | B | C
...is true if any of the symbols A, B, and C is defined, and:
ifdef A & B & C
...is true if they all are. Note that ifndef <expr> is equivalent to ifdef !( <expr> ).
If a file of the name .moon## (moon##.dat under MS-DOS), where ## is the last two digits of the calendar year, exists in the same directory as the date file (or in the directory where pcal resides), pcal uses the information contained within to calculate the phase of the moon. If a) no such file exists, b) the -e flag (do not use a date file) is specified, or c) the -z flag (specify time zone) is specified, then pcal uses an algorithm to calculate the phase of the moon.
Entries in the moon file must conform to the following syntax:
If the -A option (American date formats, the default) is given:
<quarter> <month><sep><day> {<hour><sep><min>}
If the -E option (European date formats) is given:
<quarter> <day><sep><month> {<hour><sep><min>}
Where:
<quarter> := ``nm'', ``fq'' or ``1q'', ``fm'', ``3q'' or ``lq'' (new moon, first quarter, full moon, last quarter) <hour> := number 0-23 (24-hour clock) <min> := number 0-59
This file must contain entries for all quarter moons in the year, in chronological order; if any errors are encountered, pcal will revert to using its default algorithm.
As in the date file, comments start with `#' and run through the end of the given line.
The moon file may optionally contain an opt -A or opt -E line to specify the format of its own date entries independently of the format used in the date file. No other flags are legal in the moon file.
PostScript-format pcal calendars can be generated and viewed from a web browser interface.
Note: This is not to be confused with the ability to generate non-PostScript, HTML-format (using the -H command-line option) calendars, which is a different capability entirely.
Pcal comes with 4 files that provide this ability: `pcal.cgi' (a Bourne shell script), `pcal.pl' (a Perl equivalent of `pcal.cgi'), `pcal.html', and `pcalw.html'.
The CGI file (either `pcal.cgi' or `pcal.pl') must be edited before using it. Change the definition for `pcal=' (Bourne shell script) or `my $PCAL =' (Perl script) to point to the location of the pcal executable file. Change the definition for `file=' (Bourne shell script) or `my $FILE =' (Perl script) to point to the location of the pcal `date file' (e.g. `.calendar'), which contains the options for running pcal. Finally, copy the `pcal.cgi' (or `pcal.pl') file to the location where your web server expects to find such files (e.g. `/var/www/cgi-bin/').
The `pcal.html' and `pcalw.html' files must also be edited. Each one has a line like this:
<FORM ACTION="http://yourpath/cgi-bin/pcal.cgi" METHOD=GET>
That line must be edited to point to the host and location of your CGI script file (`pcal.cgi' or `pcal.pl').
Once that's done, point your web browser to the `pcal.html' or `pcalw.html' file to generate monthly/yearly PostScript calendars for viewing within your web browser.
Note: Depending upon what application your web browser spawns to preview PostScript content, the monthly calendars generated via this web browser interface may not show any embedded EPS images. For a rundown of some popular PostScript-viewing applications and whether they correctly display the embedded EPS images, see the section (above) entitled `Encapsulated PostScript (EPS) Images'.
These symbol definitions can be useful for providing alternate values in the configuration file for EPS image placement and scaling, based on paper size.
Any option taking a negative value (e.g. -Y -###) should be specified with no space between the option and the (negative) value to avoid pcal interpreting the value as an illegal flag and aborting. For example, use ` -Y-50' instead of ` -Y -50' on your option specification.
Any option (except -G and -O, for backward-compatibility) which normally takes an argument may be specified without the argument in order to reset the value to the program default. Note that while the -D option alone clears all the defined symbols, the -U option alone has no effect. The - (or -- as per System V) argument may be used to disambiguate command lines such as:
This could be written instead as one of the following:
If the environment variable PCAL_OPTS is defined, its contents are parsed as a command line. Flags set via PCAL_OPTS override the program defaults, but are overridden by options set via opt lines in the configuration file or explicitly on the command line.
The -Z flag is used to print debugging information which is of interest primarily to pcal hackers. This flag is a "hidden" flag; it does not appear as part of the usage message. At present, the following options are supported:
The subflags may be combined: e.g. "-ZDF" is equivalent to "-ZD -ZF". All of the aforementioned debugging information is written to stderr.

This old program does not seem to be included with most GNU/Linux distributions these days.

The original PostScript code to generate the calendars was written by Patrick Wood (Copyright © 1987 by Patrick Wood of Pipeline Associates, Inc.), and authorized for modification and redistribution. The calendar file inclusion code was originally written in "bs(1)" by Bill Vogel of AT&T. Patrick's original PostScript was modified and enhanced several times by King Ables, Tim Tessin, Joe Wood, Jeff Mogul, Mark Hanson, and others whose names have regrettably been lost. This C version was originally created by Ken Keirnan of Pacific Bell; additional enhancements by Joseph P. Larson, Ed Hand, Andrew Rogers, Mark Kantrowitz, Joe Brownlee, Andy Fyfe, Steve Grandi, Geoff Kuenning, Stefan Fronzek (1-column HTML output), Bill Bogstad (event deletion capability), and Bill Marr (embedded EPS images, command-line paper size specification, new paper sizes [legal & tabloid], additional character mappings for new languages, and various cleanups). The moon routines were originally written by Jef Poskanzer and Craig Leres, and were incorporated into pcal by Richard Dyson. International language support was initially added by Angelo Haritsis. Additional languages were added by Andrew Rogers (Esperanto), Lars Wirzenius (Finnish), Pedro Zorzenon Neto (Portuguese), Joel Fredrikson (Swedish), Volodymyr M. Lisivka (Ukrainian), Neeme Praks (Estonian, Russian, Latvian, Lithuanian), Peter Cernoch (Czech), Ferenc Kruzslicz (Hungarian), Carles Sadurni Anguita (Catalan), Dominik 'Chiron' Derlatka (Polish), Ewald Beekman (Dutch), Claudiu Costin (Romanian), Kenneth Geisshirt (Danish), Zdenko Podobny (Slovak), and Eric Nichols (Hawaiian).
