+{{{testport}}} is a Bash script to test install a specified port in a custom MacPorts location in the {{{/opt}}} directory.
+
+The default location is {{{/opt/macports-test}}}.

+# 1. move the /opt/local MacPorts system to ${opt_local_off} to make sure it is not interfering with the custom ${MP_PREFIX} MacPorts build process
+# 2. move /usr/local to ${usr_local_off} to make sure it is not interfering with the custom ${MP_PREFIX} MacPorts build process
+# 3. install a fresh MacPorts 2.0.4 system to "${MP_PREFIX}"
+# 4. install the specified port to the custom ${MP_PREFIX} MacPorts system
