# this is a special target for testing a package on Windows from a non-Windows
# host. It builds the Windows test binary, then SCPs it to the Windows host, and
# runs the tests there. This depends on the GO_REMOTE_WINDOWS environment
# variable being set as 'username@host'. The Windows host must have Git Bash
# installed, or maybe MSYS2, so that a number of standard Unix tools are
# available. Git must also be configured with a username and email address. See
# the GitHub workflow config in .github/workflows/build.yml for hints.
# A recent PowerShell is also required, such as version 7.3 or later.
#
# An F: drive is expected to be available, with a tmp directory. This is used
# to make sure gomplate can deal with files on a different volume.
