# gcalltx.pl -- (C) Claus-Peter R"uckemann, 1996, 1998, 1999
#
# version 1.6 (superseeds previous gcalltx.sed 1.5 & gcalltx.in/sh 1.5)
#
#
# This file may be distributed with Gcal under the terms
# of the GNU public license.
#
#
# This script may be used to convert 'gcal -n -u %0001 year' output to
# LaTeX tabular output.
#
# Linux/UN*X solution.
#
# Tested on Linux (where else) 2.0.3*
# with perl 5.*, bash 2.01.0*, teTeX 0.4*, LaTeX209 and LaTeX2e.
# But others should do also.
#
#
# This simple script converts 'gcal -n -u %0001 year' output to LaTeX
# tabular/longtable output for gcal. Any but default configuration might
# confuse this script.  It has been created from a previous UN*X shell script
# and sed script. This program has been tested with the German, English and
# French catalogs of gcal under Linux, IBM/AIX, SUN/Solaris.
# (MSDOgS/Win* untested so far. Remember you need some prerequisites on
# these systems like a running perl 5.*, nl or below replacement and you
# need to modify the $gcaltmp=`...`; calls for those systems I believe.)
# It should accept all country codes gcal uses.
#
# It is *** not *** guaranteed that this script works for any other call than
# the one given above and the ones given in the -help section but it could
# easily be modified and extended for using your favorite PostScript fonts,
# color, shading, tabulars modifications ... under LaTeX2e.
#
# For LaTeX2e longtable.sty is used when using the -longtable option.
# For consistance with the older versions splitting can still be done by
# introducing BREAKPOINT marks at defined offsets into the gcal output and
# creating separate tabulars for LaTeX209.
# If you are not satisfied with the different width of the tabulars in the
# LaTeX209 version you could use *-form, p-columns or/and experiment with
# \extracolsep without using the -longtable option and LaTeX2e.
# The "breakpoint part" from the previous scripts has been reduced to a
# minimum while not having changed the concept (nl is used instead of sed =).
# Comment these parts and no splitting will be done.
# If you comment the part called "breakpoint part" in the scripts
# you could set \textheight to 28cm and \voffset to -3.0cm and change the
# normalsize font environment in here to small (center has explicitly
# been set to reduce memory usage -- page wise).
#
# If you modify this script you have to rename the modified version.
#
# Remarks:
# -- No hassling anymore with 'empty last lines in different sed versions'.
# -- This source uses 7-bit representations for 8-bit characters.
#    You can easily recognize them because they are translated into their
#    LaTeX counterpart.
# -- If you extend take care in not mixing the codepages and language
#    dependend patterns too much. (This is still valid.)
# -- This program is a lot faster than the previous sed version so you
#    should have no need anymore to commenting out language dependend stuff
#    for languages you do not need in order to increase speed :-).
#
# If you make any improvements I would like to hear from you.
# But I do not (cannot) promise any support.

# ODYSSEY:
#
# 19960807 CPR version 1.0  (sed/shell script)
# 19961104 CPR version 1.1  (sed/shell script)
# 19971218 CPR version 1.2  (sed/shell script)
# 19980228 CPR version 1.2b (sed/shell script)
# 19980626 CPR version 1.5  (sed/shell script)
# 19990105 CPR version 1.6  (Perl)
#              Rewrite of gcalltx.sed (1.5) & gcalltx.in/sh (1.5) prototypes
#              (More or less a hack in order to migrate the shell script and
#              sed sources to Perl.)
#              This is going along with ;-):
#              Shell script and pattern (sed) script are *one* source now.
#              Less system calls.
#              8-bit chars are represented as nice 7-bit HEX escapes now :-).
#              Usage of tmp files is completely reduced.
#              Future extensions should be easier and more portable (I hope).
#              A lot better performance.
# 19990106 CPR -longtable
#              Added LaTeX2e longtable support.
# 19990106 CPR -miscindex
#              Added index creation.
# 19990107 CPR -makedvi
#              Added optional latex/makeindex calls..
# 19990108 CPR -longsample
#              Added list of country codes. Called it long*sample* because I
#              cannot guarantee if the list coded in here contains all of the
#              countries supported by gcal at any time.
# 19990108 CPR Added short forms for the above options (-lt -mi -md -ls)
#              in order to reduce command line size.
# 19990108 CPR Some of the LaTeX2e output has been successfully tested with
#              latex2html 98.1 without further preparation.
#              (gcalltx -longtable -miscindex DE+GB+MX+NO 1998+2001)
# 19990108 CPR -stdout
#              Added switch to direct output to STDOUT instead of a LaTeX
#              file. This might be used for further postprocessing :-).
# 19990227 tom Completed list of country codes.  Ending message suppressed
#              in case -stdout option is used.  Managed handling of a
#              transformed Gcal executable name which is other than `gcal'.
#              The new output column positions in the eternal holiday list
#              of the actual Gcal are respected now.
# 19990322 tom Managed handling of a transformed script installation name
#              other than `gcalltx.pl'.
# 19990602 tom Postprocessing of Czech `...Jan Hus...' holiday added for
#              removing an unnecessary tabular delimiter which was inserted
#              accidentially.
# 19990917 tom Removed a typo in the help screen, added $VERSION, proper
#              management of `gcal' program call, working `--help' option.
# 19991108 tom Removed the term ``standard holidays'' in all texts and added
#              more countries/territories to the `-longsample' option.
# 19991121 CPR Checked usage with the new country codes.
#              Fixed new (AN_BO) into (AN\_BO) for the LaTeX results
#              as this would cause errors LaTeX'ing.
#              Checked the examples given with the standard help (--help/-?).
#              Working with the new country codes now.
#              Puuh, these lists are comfortably huge now. =B-)
# 19991122 CPR Added rule to add those new country codes to the index.
#              Added new (Ast) (Chi) (Per) ... to the index.
#
# I might clean up the $gcaltmp and numberless print's one day.
