- *
- * Usage:
- *
- *  $locale=al2gt(<array of supported languages/charsets in gettext syntax>,
- *                <MIME type of document>);
- *  setlocale('LC_ALL', $locale); // or 'LC_MESSAGES', or whatever...
- *
- * Example:
- *
- *  $langs=array('nl_BE.ISO-8859-15','nl_BE.UTF-8','en_US.UTF-8','en_GB.UTF-8');
- *  $locale=al2gt($langs, 'text/html');
- *  setlocale('LC_ALL', $locale);
- *
- * Note that this will send out header information (to be
- * RFC2616-compliant), so it must be called before anything is sent to
- * the user.
- * 
- * Assumptions made:
- * * Charset encodings are written the same way as the Accept-Charset
- *   HTTP header specifies them (RFC2616), except that they're parsed
- *   case-insensitive.
- * * Country codes and language codes are the same in both gettext and
- *   the Accept-Language syntax (except for the case differences, which
- *   are dealt with easily). If not, some input may be ignored.
- * * The provided gettext-strings are fully qualified; i.e., no "en_US";
- *   always "en_US.ISO-8859-15" or "en_US.UTF-8", or whichever has been
- *   used. "en.ISO-8859-15" is OK, though.
- * * The language is more important than the charset; i.e., if the
- *   following is given:
- * 
- *   Accept-Language: nl-be, nl;q=0.8, en-us;q=0.5, en;q=0.3
- *   Accept-Charset: ISO-8859-15, utf-8;q=0.5
- *
- *   And the supplied parameter contains (amongst others) nl_BE.UTF-8
- *   and nl.ISO-8859-15, then nl_BE.UTF-8 will be picked.
- * 
- * $Log: accept-to-gettext.inc,v $
- * Revision 1.1.1.1  2003/11/19 19:31:15  wouter
- * * moved to new CVS repo after death of the old
- * * Fixed code to apply a default to both Accept-Charset and
- *   Accept-Language if none of those headers are supplied; patch from
- *   Dominic Chambers <dominic at encasa.com>
- *
- * Revision 1.2  2003/08/14 10:23:59  wouter
- * Removed little error in Content-Type header syntaxis.
