Re: [tycho-user] Pack200'd artifacts w/o unpacked ones?

[Nick Boldt <nboldt@xxxxxxxxxx>]

What's the best way to suggest an includeOnlyPackedArtifacts=true or
excludeUnpackedArtifactIfPackedArtifactAvailable=true option when
building an update site (p2 repo) with Tycho?

bugzilla? mailing list? PR against github repo?
