.SH NAME
locale \- describes a locale definition file
.SH DESCRIPTION
The
.B locale
-definition files contains all the information that the
+definition file contains all the information that the
.BR localedef (1)
command needs to convert it into the binary locale database.
The definition files consist of sections which each describe a
locale category in detail.
+See
+.BR locale (7)
+for additional details for these categories.
.SS Syntax
The locale definition file starts with a header that may consist
of the following keywords:
.TP
-.I <escape_char>
+.I escape_char
is followed by a character that should be used as the
escape-character for the rest of the file to mark characters that
should be interpreted in a special way.
It defaults to the backslash (\\).
.TP
-.I <comment_char>
+.I comment_char
is followed by a character that will be used as the
comment-character for the rest of the file.
It defaults to the number sign (#).
can be defined from scratch.
If the category should be copied,
the only valid keyword in the definition is
-.B copy
-followed by the name of the locale which should be copied.
-.\" FIXME glibc 2.2.2 added new nonstandard locale categories:
-.\" LC_ADDRESS, LC_IDENTIFICATION, LC_MEASUREMENT, LC_NAME,
-.\" LC_TELEPHONE. These need to be documented.
+.I copy
+followed by the name of the locale in double quotes which should be
+copied.
+The exceptions for this rule are
+.B LC_COLLATE
+and
+.B LC_CTYPE
+where a
+.I copy
+statement can be followed by locale-specific rules and selected overrides.
+.PP
+When defining a category from scratch, all field descriptors and strings
+should be defined as Unicode code points in angle brackets, unless
+otherwise stated below.
+For example, "€" is to be presented as "<U20AC>", "%a" as
+"<U0025><U0061>", and "Monday" as
+"<U0053><U0075><U006E><U0064><U0061><U0079>".
+Values defined as Unicode code points must be in double quotes, plain
+number values are not quoted (but
+.BR LC_CTYPE
+and
+.BR LC_COLLATE
+follow special formatting, see the system-provided locale files for
+examples).
