+An X Locale Database contains the subset of a user's environment that
+depends on language, in X Window System. It is made up from one or more
+categories. Each category consists of some classes and sub-classes.
+</para>
+
+<para>
+It is provided as a plain ASCII text file, so a user can change its
+contents easily. It allows a user to customize the behavior of
+internationalized portion of Xlib without changing Xlib itself.

+<para>
+The X Locale Database contains one or more category definitions.
+This section describes the format of each category definition.
+</para>
+
+<para>
+The category definition consists of one or more class definitions.
+Each class definition has a pair of class name and class value, or
+has several subclasses which are enclosed by the left brace ({) and
+the right brace (}).
+</para>
+
+<para>
+Comments can be placed by using the number sign character (#).
+Putting the number sign character on the top of the line indicates
+that the entire line is comment. Also, putting any whitespace character
+followed by the number sign character indicates that a part of the line
+(from the number sign to the end of the line) is comment.
+A line can be continued by placing backslash (\) character as the
+last character on the line; this continuation character will be
+discarded from the input. Comment lines cannot be continued on
+a subsequent line using an escaped new line character.
+</para>
+
+<para>
+X Locale Database only accepts XPCS, the X Portable Character Set.
+The reserved symbols are; the quotation mark("), the number sign (#),
+the semicolon(;), the backslash(\), the left brace({) and
+the right brace(}).

+Elements separated by vertical bar (|) are alternatives. Curly
