Question for current maintainers: ./README: new release?

Also:

* Moving out eompi & eoserial modules (issue #2).

* Correction of the errors when executing "make doc" command.

* Adding a solution for the conflicting headers problem (see the two CMake Cache
 Values: PROJECT_TAG & PROJECT_HRS_INSTALL_SUBPATH) (issue #1)

* Header inclusions:
        ** src: changing absolute paths into relative paths ('#include <...>' -> '#include "..."')
        ** test, tutorial: changing relative paths into absolute paths ('#include "..."' -> '#include <...>')

* Moving out some scripts from EDO -> to the root

* Add a new script for compilation and installation (see build_gcc_linux_install)

* Compilation with uBLAS library or EDO module: now ok

* Minor modifications on README & INSTALL files

* Comment eompi failed tests with no end

How to install EoMPI
====================
Install OpenMpi
---------------
1) Download OpenMPI on their website or with the following command:
wget http://www.open-mpi.org/software/ompi/v1.6/downloads/openmpi-1.6.tar.bz2
2) Untar the downloaded archive in a directory and change working directory to there:
tar -xvjf openmpi*.tar.bz2
cd openmpi-X.Y
3) Use configuration script to indicate in which directory OpenMPI should be installed, and other options:
Simplest configuration:
./configure --prefix=/home/`whoami`/openmpi/
Only static libraries:
./configure --enable-static --disable-shared
Only static libraries, with prefix, disable build for Fortran77 and Fortran90, add support for SGE:
./configure --enable-static --disable-shared --prefix=/home/`whoami`/openmpi/ --disable-mpi-f77 --disable-mpi-f90 --with-sge
Other options are available in the README file.
4) Make it and install:
In sequential:
make all install
Or in parallel:
make -j 2 all
make install
5) Try to compile and run the sample program:
~/openmpi/bin/mpicxx -o sample mpi.c
~/openmpi/bin/mpirun -np 3 ./sample
Configure EO to use MPI
-----------------------
You only need to configure eo-conf.cmake so as to use MPI :
1) Put the WITH_MPI boolean to true:
SET(WITH_MPI TRUE CACHE BOOL "Use mpi ?" FORCE)
2) Indicate in which directories you have installed openmpi:
SET(MPI_DIR "/where/did/you/install/openmpi" CACHE PATH "OpenMPI directory" FORCE)
3) Recompile eo:
./distclean
./build_gcc_linux_release.sh
4) If you meet any issue, don't hesitate to contact the EO mailing list:
eodev-main@lists.sourceforge.net
