Guys,

Seriously..

Why, do I have zip files inside zip files with the same name?

Open nipp438.zip and it has in it.

license_agreement.txt
nipp438.zip
readme.html

Now double click that nipp438.zip and get your files. nipp508.zip
does the same thing.

Don't feel bad, the Aug 8 2008 named.nlm update comes in named.zip.zip.
Maybe it secretly wanted to be a zip within a zip, jealous of NIPP
which gets all the attention :)
