# configuration file for hcal - Hebrew calendar program\n\
# part of package libhdate\n\
#\n# Should you mangle this file and wish to restore its default content,\n\
# rename or delete this file and run hcal; hcal will automatically\n\
# regenerate the default content.\n#\n\
# Your system administrator can set system-wide defaults for hcal by\n\
# modifying file <not yet implemented>.\n\
# You may override all defaults by changing the contents of this file.\n\
#\n\
# Version information\n\
# This may be used by updates to hcal to determine how to parse the file\n\
# and whether additional information and options should be appended to\n\
# the end of this file.\n\
VERSION=2.00\n\
# Location awareness\n\
# hcal wants to accurately highlight the current Hebrew day, including\n\
# during the hours between sunset and secular midnight. If you don't\n\
# provide it with latitude, longitude, and time zone information, hcal\n\
# will try to guess the information, based upon your system timezone,\n\
# and its (limited, and maybe biased) of the dominant Jewish community\n\
# in that timezone. When hcal is forced to guess, it alerts the user\n\
# with a message that includes the guessed location.\n\
# hcal's guesses will also affect its default behaviour for output of\n\
# Shabbat times, parshiot, and choice of Israel/diaspora hoidays\n\
#SUNSET_AWARE=TRUE\n\
# LATITUDE and LONGITUDE may be in decimal format or in the form\n\
# degrees[:minutes[:seconds]] with the characters :'\" as possible\n\
# delimiters. Use negative values to indicate South and West, or\n\
# use the abbreviated compass directions N, S, E, W.\n\
#LATITUDE=\n\
#LONGITUDE=\n\
# TIMEZONE may may be in decimal format or in the form degrees[:minutes]\n\
# with the characters :'\" as possible delimiters.\n\
#TIMEZONE=\n\n\
# Israel and the diaspora\n\
# If hcal guesses that you're not in Israel, the DIASPORA option will be\n\
# set true. This will affect holiday and parasha output. FORCE_ISRAEL\n\
# forces hcal to display calendar information for Israel, using hcal's\n\
# default coordinates foe Israel, or coordinates that you provide that\n\
# seem legitmately within Israel.\n\
# Thus, if you are living in Sao Paolo, and will be visiting Israel for\n\
# Sukkot, set BOTH flags true in order to see holiday information for\n\
# a non-resident vistor to Israel. The command line options for these\n\
# features are --israel, -I, --diaspora, -d.\n\
#FORCE_DIASPORA=FALSE;\n\
#FORCE_ISRAEL=FALSE;\n\n\
# Shabbat related\n\
# Setting SHABBAT_INFO true will output parshiot and Shabbat times.\n\
# The command line options for these features are -p (--parasha), and\n\
# -s (--shabbat). The CANDLE_LIGHTING field can accept a value of 18 - 90 (minutes\n\
# before sunset). The HAVDALAH field can accept a value of 20 - 90\n\
# (minutes after sunset).\n\
#PARASHA_NAMES=FALSE\n\
#SHABBAT_INFO=FALSE\n\
#CANDLE_LIGHTING=FALSE\n\
#HAVDALAH=FALSE\n\n\
# Holiday identification\n\
# hcal flags holidays by replacing the gregorian/Hebrew date separator\n\
# with assorted unhelpful cryptic symbols. Setting FOOTNOTES to true\n\
# will have hcal output after the month's calendar, a list of the month's\n\
# holidays along with the days on which they occur.\n\
#FOOTNOTE=FALSE\n\n\
# Output in hebrew characters\n\
# hcal defaults to output all information in your default language, so\n\
# if your default language is Hebrew, you're all set. Otherwise, you can\n\
# set FORCE_HEBREW to true to output Hebrew information in Hebrew, while\n\
# still outputting gregorian information in your default language. To\n\
# output ALL information in Hebrew, run something like this:\n\
# LC_TEMP=LC_ALL; LC_ALL=\"he_IL.UTF-8\"; hcal; LC_ALL=$LC_TEMP\n\
# If setting FORCE_HEBREW to true results in 'garbage' or non-Hebrew\n\
# output, you need to install a terminal font that includes the Hebrew\n\
# character set (hint: unicode).\n\
# The command line option for FORCE_HEBREW is either --hebrew or -H\n\
#FORCE_HEBREW=FALSE\n\n\
# The FORCE_HEBREW option outputs data that is 'correct' and 'logical'.\n\
# Unfortunately, the world can not be depended upon to be either. Most\n\
# Xwindow applications will display the data fine with FORCE_HEBREW; most\n\
# xterm implementations will not. (in fact, the only xterm clone I know\n\
# of that comes close is mlterm). If using FORCE_HEBREW results in\n\
# Hebrew characters being displayed in reverse, set OUTPUT_BIDI to true.\n\
# This will reverse the order of the Hebrew characters, so they will\n\
# display 'visual'ly correct; however, such output will not be suitable\n\
# for piping or pasting to many other applications. Setting OUTPUT_BIDI\n\
# automatically forces hebrew.\n\
# The command line option for OUTPUT_BIDI is either --bidi, --visual, or -b\n\
#OUTPUT_BIDI=FALSE\n\n\
# Display enhancements\n\
# hcal defaults to display the current day in reverse video\n\
# The command line option for this feature is --no-reverse\n\
#SUPPRESS_REVERSE_VIDEO=FALSE;\n\
# hcal can display its output \"calming, muted tones\". Note that piping\n\
# colorized output may yield unexpected results.\n\
#COLORIZE=FALSE\n\n\
# HTML OUTPUT\n\
#OUTPUT_HTML=FALSE\n\
#USE_EXTERNAL_CSS_FILE=\"pathto/foo/bar\"\n\n\
# Suppress alerts and warnings\n\
# hcal alerts the user via STDERR when it guesses the user's location.\n\
#QUIET_ALERTS=FALSE\n\n\
# Three month display\n\
# hcal can display a previous, current and next month side-by-side. hcal\n\
# can also display a calendar for an entire year in four rows of three\n\
# months each. Note that this will display properly only if your console\n\
# is set for at least 127 columns. Note also that setting this option to\n\
# will cause options FOOTNOTES, SHABBAT, and PARASHA_NAMES to false.\n\
#THREE_MONTH=FALSE\n\n\
# User-defined menus\n\
# You may specify here command-line strings to optionally be parsed\n\
# by hcal at execution time. To do so, use the command line option -m\n\
# (--menu). hcal will process first the settings of this config file,\n\
# then the other settings of your command line, and then will prompt\n\
# you for which menu item you would like to select. hcal will process\n\
# your menu selection as if it were a new command line, further modifying\n\
# all the prior settings.\n\
# Only the first ten \"MENU=\" entries will be read. Each line will be\n\
# truncated at one hundred characters\n\
#MENU= -l -23.55 -L -46.61 -z -3 # parents in Sao Paolo\n\

* on Unix-like systems, the LANG environment variable. For
* example, this means that if your LANG variable is set to a

* specified to work). You can then use the wide-character
* versions of all the standard functions. However, if you
* really do want to count characters rather than bytes, and
* can assume that your text files are encoded in UTF-8, then
* the easiest approach is to count all bytes that are not
* trail bytes (i.e., in the range 0x80 to 0xBF)."
