Create your own .paf

Can anybody please tell me if (and where) the packager to create my own .paf can be downloaded?

I would like to package 1 or 2 apps that I use pretty frequently but since they are not freeware I cannot ask anybody else to package them for me.

If I could download the tool to package them I could finally use them in the same way I use other .paf applications and also launch them from my USB flash drive.

Thanks in advance and best regards,

Spicy
