 EPW v5.9 is an open-source community code for ab initio calculations of electron-phonon 
 interactions using Density-Functional Perturbation Theory and Maximally Localized Wannier 
 Functions.
 EPW is distributed as part of the Quantum ESPRESSO suite, therefore please cite
     "P. Giannozzi et al., J. Phys.:Condens. Matter 21 395502 (2009);

 The software tree of EPW v5.9 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 http://epw.org.uk/Documentation/Tutorial
 /src ==> Contains all the EPW source files.
 ../test-suite/epw_* ==> 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. 
 /ZG  ==> A set of codes for calculations of electron-phonon interactions via the
          special displacement method.
 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.
