skolo/go/win/gen-unattend/main.go

// Generate unattend.xml files for multiple devices based on config files.
//
// Setup:
//  - Check out the buildbot repo.
//  - Create two config files, devices.json5 and vars.json5 (examples in this directory).
//  - Create the output directory, if necessary.
//
// Usage (assuming the CWD contains devices.json5 and vars.json5):
//   gen_unattend --resources-dir C:\path\to\buildbot\skolo\win \
//     --out-dir C:\RemoteInstall\WdsClientUnattend
