+# This script builds the 2 plugins that are included in the Audacity
+# distribution.
+#
+# Since we do not include the plugin source as part of Audacity, we
+# must retrieve it first, followed by configure.  However, we do not
+# use the constructed Makefile since we only need 2 of the plugins and
+# it is not universal binary friendly.
+#
+# In addition, each plugin has an initialization routine that must be
+# executed before the plugin can be used.  The plugin distribution does
+# not provide support for this on OSX so, by default, the initialization
+# routine never gets executed.
+#
+# Therefore, we assign the constructor attribute to the initialization
+# routine which causes the routine to be executed as soon as the plugin
+# is loaded.

+# Set to the URL to the plugins source distribution
