+
+ This file format is the format used by the Perseus software
+ (http://www.sas.upenn.edu/~vnanda/perseus/) by Vidit Nanda.
+ The first line contains a number d begin the dimension of the

+/*! \page installation GUDHI installation
+ *  \tableofcontents
+ * As GUDHI is a header only library, there is no need to install the library.
+ * 
+ * Examples of GUDHI headers inclusion can be found in \ref utilities.
+ * 
+ * \section compiling Compiling
+ * The library uses c++11 and requires <a target="_blank" href="http://www.boost.org/">Boost</a>  &ge; 1.48.0
+ * and <a target="_blank" href="https://www.cmake.org/">CMake</a> &ge; 3.1.
+ * It is a multi-platform library and compiles on Linux, Mac OSX and Visual Studio 2015.
+ * 
+ * \subsection utilities Utilities and examples
+ * To build the utilities, run the following commands in a terminal:
+\verbatim  cd /path-to-gudhi/
+mkdir build
+cd build/
+cmake ..
+make \endverbatim
+ * By default, examples are disabled. You can activate their compilation with
+ * <a href="https://cmake.org/cmake/help/v3.0/manual/ccmake.1.html">ccmake</a> (on Linux and Mac OSX),
+ * <a href="https://cmake.org/cmake/help/v3.0/manual/cmake-gui.1.html">cmake-gui</a> (on Windows) or by modifying the
+ * cmake command as follows :
+\verbatim  cmake -DWITH_GUDHI_EXAMPLE=ON ..
+make \endverbatim
+ * A list of utilities and examples is available <a href="examples.html">here</a>.
+ * 
+ * \subsection libraryinstallation Installation
+ * To install the library (headers and activated utilities), run the following command in a terminal:
+ * \verbatim  make install \endverbatim
+ * This action may require to be in the sudoer or administrator of the machine in function of the operating system and
+ * of <a href="https://cmake.org/cmake/help/v3.0/variable/CMAKE_INSTALL_PREFIX.html">CMAKE_INSTALL_PREFIX</a>.
