preproc.sh now translates the {{INSTALL_PREFIX}} string as well as the
{{OWLPS_VERSION}} string. Both values are now obtained from the
corresponding environment variables (OWLPS_VERSION was previously
obtained through a special git command).
Perl modules' man pages should be named Foo::Bar.3perl instead of
Foo--Bar.3perl. This is fixed but the solution is incomplete and hacky,
due to a limitation of make: Foo--Bar.3perl is first generated, then
renamed to Foo::Bar.3perl. This breaks the dependencies and
Foo--Bar.3perl will be re-generated at each run of make.
Doxygen comments are now used in libowlps, libowlps-client and
libowlps-resultreader. doc/Doxyfile was added as well as CMake rules to
generate man pages for the libraries' header files.
