+# LOCALIZATION NOTE:
+# Strings here are used to create events and tasks with start and end times
+# based on email content.
+# None of the strings are displayed in the user interface.
+#
+# You don't have to fill all from.*, until.*, *.prefix and *.suffix patterns.
+# It's ok to leave some empty.
+# Please consider declensions and gender if your language has them.
+# Don't just translate directly. The number of variants doesn't have to be
+# the same as in en-US. All of 0, 1, 2, etc is allowed in patterns except alphabet
+# pattern. You can and should add language specific variants.
+#
+# There are two different ways to find a start time text in email:
+# 1) it matches a from.* pattern and does not have end.prefix or end.suffix next to it
+# 2) it matches until.* pattern and has start.prefix or start.suffix next to it
+# Similar inverse logic applies to end times.
+# These rules enable using prefix and suffix values with only start.* or only until.*
+# patterns localized for some languages and thus not having to repeat the same
+# values in both.
+#
+# Patterns are partially space-insensitive.
+# "deadline is" pattern will find both "deadlineis" and "deadline  is"
+# but "deadlineis" won't find "deadline is" or "deadline  is".
+# Therefore you should include all spaces that are valid within a pattern.

+# LOCALIZATION NOTE (dayOrdinalSymbol):
+# Allows to insert a string, a character or a symbol after the number of a
+# monthday in order to give it the meaning of ordinal number e.g.  1 -> 1st etc.
+# It's mainly used when formatting dates with both monthday and month name. It
+# affects the following localizable strings that hence must be localized *without*
+# any ordinal symbol for the monthday number:
+#   dayHeaderLabel, monthlyDaysOfNth_day,
+#   yearlyNthOn, daysIntervalBetweenYears,
+#   daysIntervalBetweenMonths, daysIntervalInMonth.
+# Write only a single string if the ordinal symbol is the same for every monthday, otherwise
+# write a sequence of _31_ strings (one for each monthday) separated with commas.
+# If your language doesn't require that in the mentioned strings, leave it empty.
+# e.g.
+# dayOrdinalSymbol=.
+#    -> daysIntervalInMonth: 'March 3. - 9., 2008'
+# dayOrdinalSymbol=st,nd,rd,th,th,th,th,th,th,th,th,th,th,th,th,

+# LOCALIZATION NOTE (intl.accept_languages):
+# This is a comma-separated list of valid BCP 47 language tags.
+#
+# Begin with the value of 'general.useragent.locale'. Next, include language
+# tags for other languages that you expect most users of your locale to be
+# able to speak, so that their browsing experience degrades gracefully if
+# content is not available in their primary language.
+#
+# It is recommended that you include "en-US, en" at the end of the list as a
+# last resort. However, if you know that users of your locale would prefer a
+# different variety of English, or if they are not likely to understand
+# English at all, you may opt to include a different English language tag, or
+# to exclude English altogether.
+#
+# For example, the Breton [br] locale might consider including French and
+# British English in their list, since those languages are commonly spoken in
+# the same area as Breton:
+# intl.accept_languages=br, fr-FR, fr, en-GB, en
