  This is no longer used, but code out there (such as the NSIS module on
  the SCons wiki) may try to import SCons.Sig.  If so, we generate a warning
  that points them to the line that caused the import, and don't die.
  
  If someone actually tried to use the sub-modules or functions within
  the package (for example, SCons.Sig.MD5.signature()), then they'll still
  get an AttributeError, but at least they'll know where to start looking.
