+// Package i18n supports string translations with variable substitution and CLDR pluralization.
+// It is intended to be used in conjunction with the goi18n command, although that is not strictly required.
+//
+// Initialization
+//
+// Your Go program should load translations during its initialization.
+//     i18n.MustLoadTranslationFile("path/to/fr-FR.all.json")
+// If your translations are in a file format not supported by (Must)?LoadTranslationFile,
+// then you can use the AddTranslation function to manually add translations.
+//
+// Fetching a translation
+//
+// Use Tfunc or MustTfunc to fetch a TranslateFunc that will return the translated string for a specific language.
+//     func handleRequest(w http.ResponseWriter, r *http.Request) {
+//         cookieLang := r.Cookie("lang")
+//         acceptLang := r.Header.Get("Accept-Language")
+//         defaultLang = "en-US"  // known valid language
+//         T, err := i18n.Tfunc(cookieLang, acceptLang, defaultLang)
+//         fmt.Println(T("Hello world"))
+//     }
+//
+// Usually it is a good idea to identify strings by a generic id rather than the English translation,
+// but the rest of this documentation will continue to use the English translation for readability.
+//     T("Hello world")     // ok
+//     T("programGreeting") // better!
+//
+// Variables
+//
+// TranslateFunc supports strings that have variables using the text/template syntax.
+//     T("Hello {{.Person}}", map[string]interface{}{
+//         "Person": "Bob",
+//     })
+//
+// Pluralization
+//
+// TranslateFunc supports the pluralization of strings using the CLDR pluralization rules defined here:
+// http://www.unicode.org/cldr/charts/latest/supplemental/language_plural_rules.html
+//     T("You have {{.Count}} unread emails.", 2)
+//     T("I am {{.Count}} meters tall.", "1.7")
+//
+// Plural strings may also have variables.
+//     T("{{.Person}} has {{.Count}} unread emails", 2, map[string]interface{}{
+//         "Person": "Bob",
+//     })
+//
+// Sentences with multiple plural components can be supported with nesting.
+//     T("{{.Person}} has {{.Count}} unread emails in the past {{.Timeframe}}.", 3, map[string]interface{}{
+//         "Person":    "Bob",
+//         "Timeframe": T("{{.Count}} days", 2),
+//     })
+//
+// Templates
+//
+// You can use the .Funcs() method of a text/template or html/template to register a TranslateFunc
+// for usage inside of that template.
