Announcement text: 
----------------------------------------------------------------------
This package provides macros manipulating strings, such as:
  * tests:
     - does a string contains at least n times an another?
     - does a string starts (or ends) with another? etc.
  * extractions of substrings:
     - what is on the left (or the right) of the nth occurrence of a
       substring;
     - what is between the occurrences of 2 substrings;
     - substring between 2 positions, etc.
  * substitution of all (or the n first) occurrences of a substring
    for an other substring;
  * calculation of numbers:
     - length of a string;
     - position of the nth occurrence of a substring;
     - how many times a string contains a substring?

For programming purposes, other macros allow to use special characters
(& ~ \ { } _ # $ ^ %) with the macros manipulating strings.
