#5 Installation instructions could be more helpful

[Nathan Gray]

Kudos for including instructions on how to install the prerequisites
using CPAN, but for non-perl-geeks the following instructions are not
very helpful:

"For regular UNIX systems, you can install etree-scripts like any
other Perl package."

Instead, it would be better to say something like:

"For regular UNIX systems, you can install etree-scripts with the
command (as root):

% perl Makefile.PL install

"

(assuming that's the correct command. I'm not a perl user so I don't
really know for sure.)
