`Pacote - The JavaScript Package Handler, v${version}
Usage:
pacote resolve <spec>
Resolve a specifier and output the fully resolved target
Returns integrity and from if '--long' flag is set.
pacote manifest <spec>
Fetch a manifest and print to stdout
pacote packument <spec>
Fetch a full packument and print to stdout
pacote tarball <spec> [<filename>]
Fetch a package tarball and save to <filename>
If <filename> is missing or '-', the tarball will be streamed to stdout.
pacote extract <spec> <folder>
Extract a package to the destination folder.
Configuration values all match the names of configs passed to npm, or
options passed to Pacote. Additional flags for this executable:
--long Print an object from 'resolve', including integrity and spec.
--json Print result objects as JSON rather than node's default.
(This is the default if stdout is not a TTY.)
--help -h Print this helpful text.
For example '--cache=/path/to/folder' will use that folder as the cache.
