 /**
 	A <code>OLocale</code> object represents a specific geographical, political,
 	or cultural region. An operation that requires a <code>OLocale</code> to perform
 	its task is called <em>locale-sensitive</em> and uses the <code>OLocale</code>
 	to tailor information for the user. For example, displaying a number
 	is a locale-sensitive operation--the number should be formatted
 	according to the customs/conventions of the user's native country,
 	region, or culture.

 	<P>
 	You create a <code>OLocale</code> object using one of the two constructors in
 	this class:
 	<blockquote>
 	<pre>
 	OLocale(String language, String country)
 	OLocale(String language, String country, String variant)
 	</pre>
 	</blockquote>
 	The first argument to both constructors is a valid <STRONG>ISO
 	Language Code.</STRONG> These codes are the lower-case two-letter
 	codes as defined by ISO-639.
 	You can find a full list of these codes at a number of sites, such as:
 	<BR><a href ="http://www.ics.uci.edu/pub/ietf/http/related/iso639.txt">
 	<code>http://www.ics.uci.edu/pub/ietf/http/related/iso639.txt</code></a>

 	<P>
 	The second argument to both constructors is a valid <STRONG>ISO Country
 	Code.</STRONG> These codes are the upper-case two-letter codes
 	as defined by ISO-3166.
 	You can find a full list of these codes at a number of sites, such as:
 	<BR><a href="http://www.chemie.fu-berlin.de/diverse/doc/ISO_3166.html">
 	<code>http://www.chemie.fu-berlin.de/diverse/doc/ISO_3166.html</code></a>

 	<P>
 	The second constructor requires a third argument--the <STRONG>Variant.</STRONG>
 	The Variant codes are vendor and browser-specific.
 	For example, use WIN for Windows, MAC for Macintosh, and POSIX for POSIX.
 	Where there are two variants, separate them with an underscore, and
 	put the most important one first. For
 	example, a Traditional Spanish collation might be referenced, with
 	"ES", "ES", "Traditional_WIN".

 	<P>
 	Because a <code>OLocale</code> object is just an identifier for a region,
 	no validity check is performed when you construct a <code>OLocale</code>.
 	If you want to see whether particular resources are available for the
 	<code>OLocale</code> you construct, you must query those resources. For
 	example, ask the <code>NumberFormat</code> for the locales it supports
 	using its <code>getAvailableLocales</code> method.
 	<BR><STRONG>Note:</STRONG> When you ask for a resource for a particular
 	locale, you get back the best available match, not necessarily
 	precisely what you asked for. For more information, look at
 	<a href="java.util.ResourceBundle.html"><code>ResourceBundle</code></a>.

 	<P>
 	The <code>OLocale</code> class provides a number of convenient constants
 	that you can use to create <code>OLocale</code> objects for commonly used
 	locales. For example, the following creates a <code>OLocale</code> object
 	for the United States:
 	<blockquote>
 	<pre>
 	OLocale.US
 	</pre>
 	</blockquote>

 	<P>
 	Once you've created a <code>OLocale</code> you can query it for information about
 	itself. Use <code>getCountry</code> to get the ISO Country Code and
 	<code>getLanguage</code> to get the ISO Language Code. You can
 	use <code>getDisplayCountry</code> to get the
 	name of the country suitable for displaying to the user. Similarly,
 	you can use <code>getDisplayLanguage</code> to get the name of
 	the language suitable for displaying to the user. Interestingly,
 	the <code>getDisplayXXX</code> methods are themselves locale-sensitive
 	and have two versions: one that uses the default locale and one
 	that uses the locale specified as an argument.

 	<P>
 	The JDK provides a number of classes that perform locale-sensitive
 	operations. For example, the <code>NumberFormat</code> class formats
 	numbers, currency, or percentages in a locale-sensitive manner. Classes
 	such as <code>NumberFormat</code> have a number of convenience methods
 	for creating a default object of that type. For example, the
 	<code>NumberFormat</code> class provides these three convenience methods
 	for creating a default <code>NumberFormat</code> object:
 	<blockquote>
 	<pre>
 	NumberFormat.getInstance()
 	NumberFormat.getCurrencyInstance()
 	NumberFormat.getPercentInstance()
 	</pre>
 	</blockquote>
 	These methods have two variants; one with an explicit locale
 	and one without; the latter using the default locale.
 	<blockquote>
 	<pre>
 	NumberFormat.getInstance(myLocale)
 	NumberFormat.getCurrencyInstance(myLocale)
 	NumberFormat.getPercentInstance(myLocale)
 	</pre>
 	</blockquote>
 	A <code>OLocale</code> is the mechanism for identifying the kind of object
 	(<code>NumberFormat</code>) that you would like to get. The locale is
 	<STRONG>just</STRONG> a mechanism for identifying objects,
 	<STRONG>not</STRONG> a container for the objects themselves.

 	<P>
 	Each class that performs locale-sensitive operations allows you
 	to get all the available objects of that type. You can sift
 	through these objects by language, country, or variant,
 	and use the display names to present a menu to the user.
 	For example, you can create a menu of all the collation objects
 	suitable for a given language. Such classes must implement these
 	three class methods:
 	<blockquote>
 	<pre>
 	public static OLocale[] getAvailableLocales()
 	public static String getDisplayName(OLocale objectLocale,
 									   OLocale displayLocale)
 	public static final String getDisplayName(OLocale objectLocale)
 	   // getDisplayName will throw MissingResourceException if the locale
 	   // is not one of the available locales.
 	</pre>
 	</blockquote>
