Profpatsch 4a7f99d55d treewide: with stdenv.lib; in meta -> with lib;
Part of: https://github.com/NixOS/nixpkgs/issues/108938

meta = with stdenv.lib;

is a widely used pattern. We want to slowly remove
the `stdenv.lib` indirection and encourage people
to use `lib` directly. Thus let’s start with the meta
field.

This used a rewriting script to mostly automatically
replace all occurances of this pattern, and add the
`lib` argument to the package header if it doesn’t
exist yet.

The script in its current form is available at
https://cs.tvl.fyi/depot@2f807d7f141068d2d60676a89213eaa5353ca6e0/-/blob/users/Profpatsch/nixpkgs-rewriter/default.nix

ngrep strives to provide most of GNU grep's common features, applying
them to the network layer. ngrep is a pcap-aware tool that will allow you
to specify extended regular or hexadecimal expressions to match against
data payloads of packets. It currently recognizes IPv4/6, TCP, UDP,
ICMPv4/6, IGMP and Raw across Ethernet, PPP, SLIP, FDDI, Token Ring and
null interfaces, and understands BPF filter logic in the same fashion as
more common packet sniffing tools, such as tcpdump and snoop.
