+# A little script to help maintaining this package. It will:
+#
+#  -  download the specified version of the extension to the store and print its url, packed store path and hash
+#  -  unpack the extension, bring it to the store and print its store path and hash
+#  -  fetch its runtimes dependencies from the 'package.json' file using the 'jq' utility, unpack those to the store
+#     and print its url store path and hash
+#  -  patch elf of the binaries that got a nix replacement
+#  -  bring the patched version to the store
+#  -  run their '--version' and call 'ldd'
+#  -  print the version of the runtime deps nix replacements.
+#
+# TODO: Print to a properly formated nix file all the required information to fetch everything (extension + runtime deps).
+# TODO: Print x86 and maybe darwin runtime dependencies.
