    Debug symbols for binary packages

    Does FreeBSD support download of debugging symbols for binary packages installed via pkg? I can't find any information about that nor can I find any packages with those symbols. I'm heavy ports user but recently I wanted to debug something quickly and wanted to avoid building in myself from ports.

    Other Debugging and automated testing of C# mono programs?

    Does anybody know any useful tools on the subject? I have a lang/mono application written in C# which runs fine, but it's not perfect yet. Personally I wouldn't ever use any .NET stuff, but I have to deal with this now. Maybe sometime later I'll re-write it in plain C though.
