Hi Zaro, A few comments - hopefully your mentors can chime in with a bit more: Your repo appears to contain GNU coreutils, which is not part of the = FreeBSD base system and is GPLv3 code, so for legal reasons a lot of = FreeBSD developers can't look at it and most shouldn't if they are = planning on working on any similar parts of the FreeBSD system. I = believe that the socsvn server is isolated from the main svn repository, = but putting GPLv3 code in any FreeBSD svn server can open the project to = liability, so I would ask you to remove it as soon as possible. Second, your SOL appears to be using yajl. This project was intended to = use libucl and libnv as the human-readable and binary serialization = mechanisms, as those are already present in the base system. Have you = spent any time yet looking at them? Are there limitations in their APIs = and the structures that they can represent?
