+Hi,
+
+some operating systems use PREFIX/man instead of PREFIX/share/man as the base
+directory for man pages and PREFIX/libexec/ instead of PREFIX/lib/ for files
+like CGI programs.
+At the moment the location of the installed man pages and the w3m cgi wrapper
+is hard-coded in Makefile.PL.
+The patch below makes it possible to install those files to alternative directories
+while the default stays as it is now.
+
+<pre>
+
+  - Introduce two variables, IKI_MANDIR and IKI_W3MCGIDIR, to be set from
+    the command line. This enables locations for man pages and the w3m
+    cgi wrapper other than the hard-coded defaults in Makefile.PL.
