* This array specifies the available translations.
*
* Structure of array:
* $languages['language']['variable'] = 'value'
*
* Possible 'variable' names:
* NAME - Translation name in English
* CHARSET - Encoding used by translation
* ALIAS - used when 'language' is only short name and 'value' should provide long language name
* ALTNAME - Native translation name. Any 8bit symbols must be html encoded.
* LOCALE - Full locale name (in xx_XX.charset format). It can use array with more than one locale name since 1.4.5 and 1.5.1
* DIR - Text direction. Used to define Right-to-Left languages. Possible values 'rtl' or 'ltr'. If undefined - defaults to 'ltr'
* XTRA_CODE - translation uses special functions. See http://squirrelmail.org/docs/devel/devel-3.html
*
* Each 'language' definition requires NAME+CHARSET or ALIAS variables.
*
* @name $languages
* @global array $languages
