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

longDescription = ''
pagemon is an ncurses based interactive memory/page monitoring tool
allowing one to browse the memory map of an active running process
on Linux.
pagemon reads the PTEs of a given process and display the soft/dirty
activity in real time. The tool identifies the type of memory mapping
a page belongs to, so one can easily scan through memory looking at
pages of memory belonging data, code, heap, stack, anonymous mappings
or even swapped-out pages.
