Subject: scripts: package-metadata add pkgmanifestjson call
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=3128dfc18a5eaff145d17b8a3fe1131d10922384;p=openwrt%2Fstaging%2Flinusw.git

scripts: package-metadata add pkgmanifestjson call

The new `pkgmanifestjson` call prints all package manifest of a feed in
JSON format. This function can be used to print an overview of packages
information used for downstream tooling.

The script is entirely based on Petrs work on dependency visualisation.
