# Builds igneum-node-windows.zip (run your own Igneum node on a Windows PC) on the Mac.
# Contents: START-NODE.bat, start-node.ps1, BUILD-NODE.bat, build-node.ps1, ALLOW-FIREWALL.bat, allow-firewall.ps1,
# README.txt, upload-log.bat (from windows-miner/), WINDOWS-MINER.md, igneum-miner.exe (cross-compiled, the status
# reader), igneumd.exe when a cross-compiled one exists, and src.zip: a `git archive` of the node worktree's HEAD under
# vendor/igneum-node/ plus igneum-pow/ from this repository's HEAD (the fork depends on it by relative path), so the PC
# can build the node with BUILD-NODE.bat without any GitHub access.
# Usage: windows-node/make-package.sh [node worktree, default vendor/igneum-node-win] [output zip, default ~/Desktop/igneum-node-windows.zip]
