Add a pack using the following "<pack>" specification or using packs provided by "-f <packs list>":

  $ cpackget add Vendor.Pack.1.2.3
  $ cpackget add Vendor::Pack@1.2.3

  Use the syntax above to let cpackget determine
  the location of pack files prior to installing it locally.

  $ cpackget add Vendor.Pack.1.2.3.pack

  Use this syntax if you already have a pack at hand and simply
  want to install it under pack-root folder.

  $ cpackget add path/to/Vendor.Pack.pdsc

  Use this syntax if you are installing a pack that has not
  been released yet. This will install it as a local pack and
  keep a reference in ".Local/local_repository.pidx".

The file can be a local file or a file hosted somewhere else on the Internet.
If it's hosted somewhere, cpackget will first download it then extract all pack files into "CMSIS_PACK_ROOT/<vendor>/<packName>/<x.y.z>/"
If "-f" is used, cpackget will call "cpackget pack add" on each URL specified in the <packs list> file.`,

  cpackget also identifies if the pack was installed via
  PDSC file. In this case, cpackget will remove its reference
  from ".Local/local_repository.pidx".

  In the first example, since just the basename of the PDSC file
  path was specified, cpackget will remove *ALL* references of the
  PDSC file it might find. Since it is possible to have many versions
  of the same pack installed via different PDSC file paths, one may
  wish to remove a specific one by specifying a more complete
  PDSC file path, as shown in the second example.

The version "x.y.z" is optional.

are *NOT* removed. If cache files need to be actually removed,
please use "--purge".`,

var SignatureCreateCmd = &cobra.Command{

	Short: "Create a digest list of a pack and signs it",
	Long: `
Generates a digest list of a pack, and signs it, creating
a detached PGP signature.

This creates a ".checksum" file, containing hashes of the contents
of the provided pack. It then gets processed and signed with a private
key, producing a PGP signature, stored in the equivalent ".signature".

If a .checksum file already exists in the target path, it will fail as to
guarantee hash freshness.

Currently Curve25519 and RSA (2048, 3072, 4096 bits) key types are supported.
If no private key (it MUST be in GPG PEM format) is provided with the -k/--key-path,
one will be created using the builtin GopenPGP module.

The contents of the generated ".checksum" file are the same as the one
created by "cpackget checksum-create":

The .signature and key files should have been created with the "signature-create" command,
as they need to be in the PEM format.

If not specified by the -s/--sig-path flag, the .signature path will be read
from the same directory as the .checksum file:

  $ cpackget checksum-verify Vendor.Pack.1.2.3.sha256.checksum signature_curve25519.key
