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
*** TODO: CPack (debian (DEB) & RedHat (RPM) packages) (issues #6 & #7) ***
