<para>These settings define where Perl looks for installed
modules. The LFS editors chose to put them in a directory structure
based on the MAJOR.MINOR version of Perl (&perl-version-min;) which
allows upgrading Perl to newer patch levels (the patch level is
the last dot separated part in the full version string like
&perl-version;) without reinstalling all of the modules.</para>
