+ Note on Perl
+ ------------
+
+ For our scripts, we rely quite a bit on Perl, and increasingly on
+ some core Perl modules. These Perl modules are part of the Perl
+ source, so if you build Perl on your own, you should be set.
+
+ However, if you install Perl as binary packages, the outcome might
+ differ, and you may have to check that you do get the core modules
+ installed properly. We do not claim to know them all, but experience
+ has told us the following:
+
+ - on Linux distributions based on Debian, the package 'perl' will
+ install the core Perl modules as well, so you will be fine.
+ - on Linux distributions based on RPMs, you will need to install
+ 'perl-core' rather than just 'perl'.
+
+ It is highly recommended that you have at least Perl version 5.12
+ installed.

Note on shared libraries
