-# A string is defined by beginning a line with an & character, which must

-# beginning of the string itself. This whitespace is never included in the
-# output.
+# A string is defined by beginning a line with one or two & characters, which
+# must be immediately followed by a C identifier. Two & characters indicates
+# a string that should not be translated, as described below. A nonempty
+# sequence of whitespace (with at most one newline) separates the identifier
+# from the beginning of the string itself. This whitespace is never included
+# in the output.
#
# The string is then interpreted as follows:
#
# and each identifier in the input is declared as an emumeration constant
# whose value is the offset of the associated string within strtab.
#
+# Normally, the generated source code wraps strings using the identity macro
+# N_(x), which has no effect on the resulting data structures but enables tools
+# such as xgettext to extract translatable strings from the source code. An
+# identifier preceded by two ampersands (&&) suppresses this output to allow
+# a single string table to also contain both translateable strings as well as
+# ones that should not be translated.
+#
# The object-like macro STRTAB_MAX_OFFSET is defined and expands to the
# greatest string offset, suitable for use in #if preprocessing directives.
