Got it from Tech Support Alert. 
Subscriber Michael C. Berrier writes "Gizmo, I routinely work
with PDF files of 200 pages or more and often have cause to extract
single pages for presentations or whatever. Even with the full
commercial version of Adobe Acrobat, that means taking out each
page one at a time unless you want to pay for an add-in. Enter Gios
PDF Splitter and Merger. Just as the site says, it's the first (and
only easily located) free and open source PDF split and merge
utility. It is indeed freeware, does not require a separate PDF
editor and works in a flash. I quickly and easily busted a 200 page
file into individual pages in far less time than I could have in
Acrobat." Nice find Michael, I really like specialized utilities
like this; it's a tiny 30KB file that doesn't require installation.
Adobe PDF format has become so widespread that it's really useful
to have available some free tools that can manipulate the PDF files
without having to buy the full Adobe Acrobat product. If other
readers are using a good free PDF utility please email me and I'll
share the news around. Freeware, Microsoft .NET V1.1 required,
