+| @description    : Your task in order to complete this Kata is to write a
+|                   function which formats a duration, given as a number of
+|                   seconds, in a human-friendly way.
+|
+|                   The function must accept a non-negative integer. If it is
+|                   zero, it just returns "now". Otherwise, the duration is
+|                   expressed as a combination of years, days, hours, minutes
+|                   and seconds.
+|
+|                   It is much easier to understand with an example:
+|
+|                   * For seconds = 62, your function should return
+|                       "1 minute and 2 seconds"
+|                   * For seconds = 3662, your function should return
+|                       "1 hour, 1 minute and 2 seconds"
+|                   For the purpose of this Kata, a year is 365 days and a day
+|                   is 24 hours.
+|
+|                   Note that spaces are important.
+|
+|                   Detailed rules:
+|                   The resulting expression is made of components like
+|                   4 seconds, 1 year, etc. In general, a positive integer and
+|                   one of the valid units of time, separated by a space. The
+|                   unit of time is used in plural if the integer is greater
+|                   than 1.
+|
+|                   The components are separated by a comma and a space (", ").
+|                   Except the last component, which is separated by " and ",
+|                   just like it would be written in English.
+|
+|                   A more significant units of time will occur before than a
+|                   least significant one. Therefore, 1 second and 1 year is
+|                   not correct, but 1 year and 1 second is.
+|
+|                   Different components have different unit of times. So there
+|                   is not repeated units like in 5 seconds and 1 second.
+|
+|                   A component will not appear at all if its value happens to
+|                   be zero. Hence, 1 minute and 0 seconds is not valid, but
+|                   it should be just 1 minute.
+|
+|                   A unit of time must be used "as much as possible". It means
+|                   that the function should not return 61 seconds, but
+|                   1 minute and 1 second instead. Formally, the duration
+|                   specified by of a component must not be greater than any
+|                   valid more significant unit of time.
