+ * \file
+ * \brief  C API: Locale 
+ *
+ * <h2> ULoc C API for Locale </h2>
+ * A <code>Locale</code> represents a specific geographical, political,
+ * or cultural region. An operation that requires a <code>Locale</code> to perform
+ * its task is called <em>locale-sensitive</em> and uses the <code>Locale</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.  In the C APIs, a locales is simply a const char string.
+ *
+ * <P>
+ * You create a <code>Locale</code> with one of the three options listed below.
+ * Each of the component is separated by '_' in the locale string.
+ * \htmlonly<blockquote>\endhtmlonly
+ * <pre>
+ * \code
+ *       newLanguage
+ * 
+ *       newLanguage + newCountry
+ * 
+ *       newLanguage + newCountry + newVariant
+ * \endcode
+ * </pre>
+ * \htmlonly</blockquote>\endhtmlonly
+ * The first option 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">
+ * http://www.ics.uci.edu/pub/ietf/http/related/iso639.txt</a>
+ *
+ * <P>
+ * The second option includes an additonal <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">
+ * http://www.chemie.fu-berlin.de/diverse/doc/ISO_3166.html</a>
+ *
+ * <P>
+ * The third option requires another additonal information--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>Locale</code> is just an identifier for a region,
+ * no validity check is performed when you specify a <code>Locale</code>.
+ * If you want to see whether particular resources are available for the
+ * <code>Locale</code> you asked for, you must query those resources. For
+ * example, ask the <code>UNumberFormat</code> for the locales it supports
+ * using its <code>getAvailable</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
+ * <code>UResourceBundle</code>.
+ *
+ * <P>
+ * The <code>Locale</code> provides a number of convenient constants
+ * that you can use to specify the commonly used
+ * locales. For example, the following refers to a locale
+ * for the United States:
+ * \htmlonly<blockquote>\endhtmlonly
+ * <pre>
+ * \code
+ *       ULOC_US
+ * \endcode
+ * </pre>
+ * \htmlonly</blockquote>\endhtmlonly
+ *
+ * <P>
+ * Once you've specified a locale you can query it for information about
+ * itself. Use <code>uloc_getCountry</code> to get the ISO Country Code and
+ * <code>uloc_getLanguage</code> to get the ISO Language Code. You can
+ * use <code>uloc_getDisplayCountry</code> to get the
+ * name of the country suitable for displaying to the user. Similarly,
+ * you can use <code>uloc_getDisplayLanguage</code> to get the name of
+ * the language suitable for displaying to the user. Interestingly,
+ * the <code>uloc_getDisplayXXX</code> methods are themselves locale-sensitive
+ * and have two versions: one that uses the default locale and one
+ * that takes a locale as an argument and displays the name or country in
+ * a language appropriate to that locale.
+ *
+ * <P>
+ * The ICU provides a number of services that perform locale-sensitive
+ * operations. For example, the <code>unum_xxx</code> functions format
+ * numbers, currency, or percentages in a locale-sensitive manner. 
+ * </P>
+ * \htmlonly<blockquote>\endhtmlonly
+ * <pre>
+ * \code
+ *     UErrorCode success = U_ZERO_ERROR;
+ *     UNumberFormat *nf;
+ *     const char* myLocale = "fr_FR";
+ * 
+ *     nf = unum_open( UNUM_DEFAULT, NULL, success );          
+ *     unum_close(nf);
+ *     nf = unum_open( UNUM_CURRENCY, NULL, success );
+ *     unum_close(nf);
+ *     nf = unum_open( UNUM_PERCENT, NULL, success );   
+ *     unum_close(nf);
+ * \endcode
+ * </pre>
+ * \htmlonly</blockquote>\endhtmlonly
+ * Each of these methods has two variants; one with an explicit locale
+ * and one without; the latter using the default locale.
+ * \htmlonly<blockquote>\endhtmlonly
+ * <pre>
+ * \code 
+ * 
+ *     nf = unum_open( UNUM_DEFAULT, myLocale, success );          
+ *     unum_close(nf);
+ *     nf = unum_open( UNUM_CURRENCY, myLocale, success );
+ *     unum_close(nf);
+ *     nf = unum_open( UNUM_PERCENT, myLocale, success );   
+ *     unum_close(nf);
+ * \endcode
+ * </pre>
+ * \htmlonly</blockquote>\endhtmlonly
+ * A <code>Locale</code> is the mechanism for identifying the kind of services
+ * (<code>UNumberFormat</code>) that you would like to get. The locale is
+ * <STRONG>just</STRONG> a mechanism for identifying these services.
+ *
+ * <P>
+ * Each international serivce 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 implement these
+ * three class methods:
+ * \htmlonly<blockquote>\endhtmlonly
+ * <pre>
+ * \code
+ *       const char* uloc_getAvailable(int32_t index);
+ *       int32_t uloc_countAvailable();
+ *       int32_t
+ *       uloc_getDisplayName(const char* localeID,
+ *                 const char* inLocaleID, 
+ *                 UChar* result,
+ *                 int32_t maxResultSize,
+ *                  UErrorCode* err);
+ * 
+ * \endcode
+ * </pre>
+ * \htmlonly</blockquote>\endhtmlonly
+ * <P>
+ * Concerning POSIX/RFC1766 Locale IDs, 
+ *  the getLanguage/getCountry/getVariant/getName functions do understand
+ * the POSIX type form of  language_COUNTRY.ENCODING\@VARIANT
+ * and if there is not an ICU-stype variant, uloc_getVariant() for example
+ * will return the one listed after the \@at sign. As well, the hyphen
+ * "-" is recognized as a country/variant separator similarly to RFC1766.
+ * So for example, "en-us" will be interpreted as en_US.  
+ * As a result, uloc_getName() is far from a no-op, and will have the
+ * effect of converting POSIX/RFC1766 IDs into ICU form, although it does
+ * NOT map any of the actual codes (i.e. russian->ru) in any way.
+ * Applications should call uloc_getName() at the point where a locale ID
+ * is coming from an external source (user entry, OS, web browser)
+ * and pass the resulting string to other ICU functions.  For example,
+ * don't use de-de\@EURO as an argument to resourcebundle.
