 # findrfuncs: find reentrant variants of functions used in an executable.
+#
 # Requires a functional "nm -u".  Searches headers in /usr/include
 # to find available *_r functions and looks for non-reentrant
 # variants used in the supplied executable.
 #
+# Requires debug info in the shared libraries/executables.
