-# * 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.
+# * When HasGuiSupport is true, the language is candidate to appear in
+# the list of possible GUI languages in the Preferences dialog. It
+# will actually appear there only if a corresponding .mo file can be
+# found among the translations. When several languages correspond to
+# the same translation -- like English, English (US) and English
+# (UK) -- try to select the entry that is most generic -- here
+# English.
+# * The QuoteStyle arguments correspond to the following styles:
+# - danish: >>text<< >text< (inward guillemets)
+# - english: ``text'' `text' (66_99)
+# - french: <<text>> <text> (outward guillemets)
+# - german: ,,text`` ,text` (99/66)
+# - polish: ,,text'' ,text' (99/99)
+# - swedish: ''text'' 'text' (99_99)
+# Note that the option names have been selected (rather arbitrarily)
+# because the respective styles are common in the respective countries.
+# Of course this does not imply any fixed relation to those countries.
+# * Encoding is the default encoding used with TeX fonts.
+# It is only used if Document > Settings > Language > Encoding
+# is set to "Language Default" and "use non-TeX fonts" is FALSE.
+# * 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 cares 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.
+# * "FontEncoding none" tells LyX that fontenc should not be loaded with this
+# language.
