TL;DR

A little utility to merge PDF files, with Perl.

So I needed to merge a few PDF files into a single one. And I knew that I already wrote about it, only in a galaxy very far far away… that has disappeared in the meanwhile.

As noted in the comments of the post from 2007, this can also be implemented through Ghostscript (if available), like this:

Now don’t trust me, try yourself!

It tends to produce slightly bloated files, while the Ghostscript-based solution is more efficient space-wise… use whatever you find better and applicable!
