stack unpack PACKAGE [--to ARG]
stack unpack downloads a tarball for the specified package and unpacks it.
By default:

the download is for the most recent version of the package in the package index (eg Hackage). Specify the package name and its version (for example,
acme-missiles-0.1.0.0) for a particular version of the package; and -
the package is unpacked into a directory named after the package and its version. Pass the option
--to <directory>to specify the destination directory.
