Followed the Migration Guide at https://cli.urfave.org/migrate-v1-to-v2/ The major changes not pointed out in the migration guide are: - context.Args() no longer produces a []slice, so context.Args().Slice() in substitued - All cli.Global***** are deprecated (the migration guide is somewhat unclear on this) Signed-off-by: Derek Nola <derek.nola@suse.com> Vendor in urfave cli/v2 Signed-off-by: Derek Nola <derek.nola@suse.com> Fix NewStringSlice calls Signed-off-by: Derek Nola <derek.nola@suse.com>
