1 # This test installs emsdk and activates the latest toolchain using `--system` or `--permanent` flags,
2 # and checks if parts of PATH are lost or overwritten. Set $env:SYSTEM_FLAG and $env:PERMANENT_FLAG to test each.
3 # If no flag is provided the process/shell values are tested. See the CI file for an example.
