New in version 5.0.
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.
platform.jsonis a manifest file of a development platform package. See Manifest File platform.json.
package.jsonis a manifest file of a tool package. It is intended for toolchains, flashers, debugging servers, simulators, and other tools.
See a manifest validation scheme.
