-# * Encoding is not relevant for XeTeX (which is utf8 always), and if
-# Document > Settings > Language > Encoding is not set to "Language
-# Default"
-# * InternalEncoding is used to tell LyX that babel internally sets a font
-# encoding (such as hebrew to LHE). See bug #5091.
-# * AsBabelOptions advices LyX to pass the languages locally to babel, not
-# globally to the class. Some languages (basically those not directly
-# supported by babel) need this.
-# FIXME: in this case, we might still need to pass the other languages
-# globally, for the use of other packages (such as varioref).
+# * DateFormats lists the localized conventions for three date forms:
+# - Long: December 1, 2018
+# - Medium: Dec 1, 2018
+# - Short: 1/12/2018
+# These are separated by | and use the QDate syntax:
+# * d the day as number without a leading zero (1 to 31)
+# * dd the day as number with a leading zero (01 to 31)
+# * ddd the abbreviated localized day name (e.g. 'Mon' to 'Sun')
+# * dddd the long localized day name (e.g. 'Monday' to 'Sunday')
+# * M the month as number without a leading zero (1 to 12)
+# * MM the month as number with a leading zero (01 to 12)
+# * MMM the abbreviated localized month name (e.g. 'Jan' to 'Dec')
+# * MMMM the long localized month name (e.g. 'January' to 'December')
+# * yy the year as two digit number (00 to 99)
+# * yyyy the year as four digit number
+# * Encoding is the default encoding used with TeX fonts.
+# It is only used if Document > Settings > Language > Encoding
+# is set to "Language Default" or "Language Default (no inputenc)"
+# and "use non-TeX fonts" is FALSE.
+# Encoding "inherit" means: keep encoding of the context (used by
+# latex_language).
+# * FontEncoding is a bar-separated list of font encodings.
+# The first value is the required font encoding for correct hyphenation with
+# 8-bit TeX (http://www.hyphenation.org). Eventually following values may be
+# used if the selected font is unavailable in FontEncoding. They provide all
+# letters used in the language, but some only as "surrogate pairs" with
+# possible problems for hyphenation and drag-and-drop from the generated
+# documents. Default: "ASCII".
+# * "FontEncoding ASCII" means: "works with any standard text encoding
+# (T<n>) as well as OT1".
+# * "FontEncoding none" tells LyX that fontenc should not be loaded with
+# this language.
+# * InternalEncoding is used to tell LyX that babel internally sets a
+# non-standard font encoding (such as hebrew to LHE or greek to LGR).
+# If True, LyX takes care for characters/macros that do not exist in
+# some font encodings ("<", ">", "|" and straight quote).
+# It is not required for standard encodings like T2A. See bug #5091.
+# * WordWrap is only used for on-screen display: when is is true (the default), rows are broken
+# at word boundary; otherwise, they can be ended at arbitrary position. This
+# setting is useful for CJK languages.
