+findsyms.py - try to identify undocumented symbols exported by modules
+
+Usage:    findsyms.py librefdir
+
+For each lib*.tex file in the libref manual source directory, identify which
+module is documented, import the module if possible, then search the LaTeX
+source for the symbols global to that module.  Report any that don't seem to
+be documented.
+
+Certain exceptions are made to the list of undocumented symbols:
+
+    * don't mention symbols in which all letters are upper case on the
+      assumption they are manifest constants
+
+    * don't mention symbols that are themselves modules
+
+    * don't mention symbols that match those exported by os, math, string,
+      types, or __builtin__ modules
+
+Finally, if a name is exported by the module but fails a getattr() lookup,
+that anomaly is reported.
