[UPDATE:]

* PLT Scheme's add-on directory can now be customized by the
PLTADDONDIR environment variable and the --addon or -A command-line
flags.  This directory is used to store downloaded Planet packages and
rendered Scribble documentation.  Customization allows multiple
installations of DrScheme to coexist without sharing (potentially
incompatible) compiled files.
