For debugging purposes, the macros: IOStreamUtilsTest.C StringTest.C TokenizeTest.C should be steered via the macro "runMacro.C", i.e.: o to start the individual applications, type: root -l runMacro.C'(".x *.C++")' with * = name of the macro (e.g. * = IOStreamUtilsTest) o to create only a shared library, type: root -l runMacro.C'(".L *.C++")'
