Yes, pdftk a frontend of iText. iText is the swiss knife of PDF manipulation. Most tools related to PDF, including many PDF printers and .NET libraries use iText. 
It is the killer library of PDF tools.

But be careful, the license doesn't allow to use it in commercial products (that includes pdftk) http://itextpdf.com/terms-of-use/index.php.
I wanted to use it and it is about 2500 eur developer license plus royalties for every copy deployed.

Nevertheless, old versions of iTextpdf (before 2010) allow something like LGPL:
