 # Pamela software is modular, so some libraries may not be available in some istallations.
 # To avoid linking problems, here you can define flags to exclude those parts of the
 # PamCut software which make use of unavailable libraries. Remember to place
 # the code to be excluded between proper preprocessor directives. See the documentation or the cut
 # TofNucleiZCut for an example.

+# Since PamCut headers may refer to the optional libraries, it's important to define the same 
+# flags when compiling the analysis code. Otherwise, analysis code will include PamCut headers which,
+# if no exclusion flag is set, will try to include optional software headers.
+# Conversely, if you use optional libraries remember to tell it to the linker.
