New in version 5.0.
pio package pack [<source directory, tar.gz or zip>] [OPTIONS]
Create a tarball from a package (library, Development Platforms, or tool).
If no arguments are supplied, then platformio packs the current package folder.
A source of a package must contain a manifest (should be located in a root of a package) depending on a package type:
A library.json is a manifest file of a library package.
A platform.json is a manifest file of a development platform package. See Manifest File platform.json.
A package.json is a manifest file of a tool package. It is intended for toolchains,
flashers, debugging servers, simulators, and other tools.
See a manifest validation scheme.
Specify a destination path (folder or a full path to file) where to store a tarball. The default is to create a tarball in the current working directory.
