+Symfony Translation Contracts
+=============================
+
+A set of abstractions extracted out of the Symfony components.
+
+Can be used to build on semantics that the Symfony components proved useful - and
+that already have battle tested implementations.
+
+See https://github.com/symfony/contracts/blob/master/README.md for more information.

+     *
+     * When a number is provided as a parameter named "%count%", the message is parsed for plural
+     * forms and a translation is chosen according to this number using the following rules:
+     *
+     * Given a message with different plural translations separated by a
+     * pipe (|), this method returns the correct portion of the message based
+     * on the given number, locale and the pluralization rules in the message
+     * itself.
+     *
+     * The message supports two different types of pluralization rules:
+     *
+     * interval: {0} There are no apples|{1} There is one apple|]1,Inf] There are %count% apples
+     * indexed:  There is one apple|There are %count% apples
+     *
+     * The indexed solution can also contain labels (e.g. one: There is one apple).
+     * This is purely for making the translations more clear - it does not
+     * affect the functionality.
+     *
+     * The two methods can also be mixed:
+     *     {0} There are no apples|one: There is one apple|more: There are %count% apples
+     *
+     * An interval can represent a finite set of numbers:
+     *  {1,2,3,4}
+     *
+     * An interval can represent numbers between two numbers:
+     *  [1, +Inf]
+     *  ]-1,2[
+     *
+     * The left delimiter can be [ (inclusive) or ] (exclusive).
+     * The right delimiter can be [ (exclusive) or ] (inclusive).
+     * Beside numbers, you can use -Inf and +Inf for the infinite.
