[NTG-context] Combining eps figures into a single document

Hi all, I am not sure if there is an easy way to do this with a generic ConTeXt document but I thought I'd ask anyways. I have a folder full of identically sized data plots saved as eps/pdf files and I was wondering if there was a quick way to shrink and tile them into a multi-page document so that I get 15 plots per page (5 rows x 3 colums)? I have scripts that generate these plots and I literally have hundreds of them that I need to combine and print. Any ideas? Many thanks, Dave
