 The software tree of EPW v4 is composed of
 /bin ==> Contains the epw.x soft link to the EPW executable.
 /examples  ==> Contains a lists of examples that are connected to the tutorials. The 
          tutorials can be found at https://epw.org.uk/Documentation/Tutorial
 /src ==> Contains all the EPW source files.
 /tests ==> Small tests useful for debugging and checking if the code works. Those tests are used
          by the test farm. Do not expect physically relevant results out of it. 

 Installation
 ------------
 To compile the code you first need to issue ./configure in /espresso. 
 Indeed EPW rely on the make.sys file created by QE. 
 Then you can run ./make inside espresso/EPW.

 EPW dedicated website and forum
