+If you are running Debian, you can just run the following:
+
+ aptitude install wget perl libhtml-element-extended-perl libxml-parser-perl
+
+Windows
+
+If you are using a windows-based machine, first consider switching to (or
+dual-booting) Debian or Ubuntu or a similar Free Software distribution. If
+switching isn't for you, you will need to install cygwin (a linux-like
+environment for windows), which (by default) will install perl and wget.
+
+You can then use the cpan commands listed above to install the required
+modules:
+
+ cpan install HTML::TreeBuilder
+ cpan install HTML::Element::Extended
+ cpan install XML::Parser
+
+Other Operating Systems
+
+If you are using another operating system (minux, MacOS 9, UNIVAX, Plan9,
+OS/2, etc.) you're on your own.
