+There are also other variables supported by MakeMaker, including PREFIX,
+INSTALL_BASE, and DESTDIR. See ExtUtils::MakeMaker(3).
+
+In particular, INSTALL_BASE is very useful if you want to install ikiwiki
+to some other location, as it configures it to see the perl libraries
+there. See `doc/tips/nearlyfreespeech.mdwn` for an example of using this to
+install ikiwiki and its dependencies in a home directory.
