 * cpptasks-1.0-beta-5-parallel-1-SNAPSHOT
 
+- added linkFortranMain option to link with gfortranbegin, see NAR-112
 - added compileOrder to the compilerDef (and thus changed most Hashtables into Maps), see NAR-109
 - added .f90 as extension for the fortran compiler, see NAR-108
 - merged with cpptasks-1.0b5.tar.gz
