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