-Use ./Makefile.PL to generate a Makefile, "make" will generate docs and a
-man page, and "make install" will install ikiwiki.
+Use ./Makefile.PL to generate a Makefile, "make" will build the
+documentation wiki and a man page, and "make install" will install ikiwiki.
-All other documentation is in the ikiwiki documentation wiki.
+All other documentation is in the ikiwiki documentation wiki, which is also

+
+
+A few special variables you can set while using the Makefile.PL:
+
+ PROFILE=1 turns on profiling for the build of the doc wiki.
+ (Uses Devel::NYTProf)
+
+ NOTAINT=0 turns on the taint flag in the ikiwiki program. (Not recommended
+ unless your perl is less buggy than mine -- see
+ http://bugs.debian.org/411786)
+
+ MAKE, FIND, and SED can be used to specify where you have the GNU
+ versions of those tools installed, if the normal make, find, and sed
+ are not GNU.
+
+ 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.
