# 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.
