+== Interaction with Traditional Zephyr ==
+
+The default athena startup scripts launch zwgc on login. If you are subscribed to many classes and use Zephyr in today's contexts, zwgc's behavior is not very desirable. To disable zwgc startup, add:
+
+{{{
+setenv ZEPHYR_CLIENT false
+}}}
+
+to your {{{~/.environment}}} file if you use {{{tcsh}}} or
+
+{{{
+ZEPHYR_CLIENT=false
+}}}
+
+to your {{{~/.bash_environment}}} if you use {{{bash}}}. This will cause your shell to launch the {{{false}}} executable instead of zwgc which does nothing.
