# Store or restore the node_modules cache on Windows.

# Usage:
#   cache.ps1 archive   # create  .build/node_modules_cache/cache.7z (cache miss)
#   cache.ps1 extract   # restore .build/node_modules_cache/cache.7z (cache hit)
#
# Uses 7-Zip. The archive and extract format must stay compatible; if you change
# the format here, bump build/.cachesalt to invalidate old caches.
