[OpenWrt-Devel] [PATCH][RFC] opkg: add License to info command

[Paul Spooren]

show license in `opkg info <pkg_name>`.

This patch isn't complete yet. It show the license info as long as the package
isn't installed. Once it's installed it seems to forget the information. I can't
figure out why. Also printing `opkg list` doesn't add the License, neither for
installed nor available.
