9# This script will update pgadmin4 in nixpkgs #
10# Due to recent changes upstream, we will need to convert the #
11# `yarn.lock` file back to version 1. #
12# This isn't trivially done and relies on 3rd party tools #
13# and a hand-written converter (in this script). #
14# Also, the converter cannot check for `github` repos in the #
15# `yarn.lock` file, which this script will add automatically #
