Created attachment 335586 [details]
The ebuild is currently labelled with LICENSE="as-is" which isn't accurate. The LICENSE.txt file in the package's tarball contains attached license. As far as I can see, it is used by no other package in the tree, so I suggest to call it "ngrep".
@Licenses team: This looks like a free software license to me. GPL incompatible though, because clause 3 is an advertising clause as in BSD-4.
