Backwards compatibility support for your Minecraft resource packs.
Drop a packmine binary into the root directory of your texture pack, in the same directory as your pack.mcmeta file.
You can now remove the pack_format property in your pack.mcmeta file but not removing it doesn't have any effect on the output.
Open the binary executable to generate the zipped and backwards compatible resource pack files.
You now only have to create a resource pack for the latest pack_format which is 4.
You can globally install the packmine package on NPM.
