+For UNIX libraries starting with **lib**, like *libmath.a*, this tool will collect the
+library name **math**. Regarding symlinks, this tool will keep only the "most generic"
+file among the resolved real file and all symlinks pointing to this real file. For example
+among files below, this tool will select *libmath.dylib* file and therefore only append
+*math* in the returned list:
