+# This CMake function generates a target that, in turn, will generate a PARfile for the given
+# library.
+#
+# Usage: in the CMakeLists.txt, for a given library, add the following:
+#   add_target_parfile(${MODULE} "${SRCS}" "${HDRS}" "${MODULE}LinkDef.h" "${LIBDEPS}" ["extrainclude1 extrainclude2..."])
+#
+# Arguments are, in order:
+#  - library's name: for libBLAHBLAH it will generate a target BLAHBLAH.par
+#  - source files: classes to include in the PARfile, they must be exactly the ones used to generate
+#    the library
+#  - headers
+#  - the LinkDef used by ROOT
+#  - dependent libraries: used to generate the rootmap
+#  - extra include paths (optional): passed during compilation
+#
+# To generate a parfile, if enabled in its CMakeLists.txt, go to the build directory and run:
+#   make BLAHBLAH.par
