22-fetchers-and-fixed-output

This example shows a pinned fetcher with fetchurl.

It includes:

• one upstream tarball fetched with fetchurl,
• a declared content hash,
• a small package that consumes the fetched file, and
• a check that verifies the tarball hash and contents.

Useful commands:

nix build
./result/bin/show-fetched-hello-source

nix run
nix flake check
