-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.

-<title>Database Format Definition</title>
-<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
-braces ({...}) indicate zero or more repetitions of the enclosed
-elements. Square brackets ([...]) indicate that the enclosed element
-is optional. Quotes ("...") are used around literal characters.
-</para>

-<para>
-The backslash, which is not the top character of the NumericString, is
-recognized as an escape character, so that the next one character is
-treated as a literal character. For example, the two-character
-sequence, ""\"""(the backslash followed by the quotation mark) is
-recognized and replaced with a quotation mark character.
-Any whitespace character, that is not the Delimiter, unquoted and
-unescaped, is ignored.
