Looks good. I am currently waiting on the swift-3-api-guidelines merge before merging anything new.

[mxcl]

I'm going to start merging everything, as I hoped the swift 3 apis would be merged this week, but it looks like it will be longer.

@swift-ci Please test

/home/buildnode/jenkins/workspace/swift-package-manager-PR-Linux/swiftpm/Sources/ManifestParser/Manifest+parse.swift:74:13: error: use of unresolved identifier 'fclose'
    defer { fclose(fp) }
            ^~~~~~
<unknown>:0: error: build had 1 command failures

This did not error for me on OSX and Ubuntu 15.10
CI looks like to be on 14.04, will check.

This is weird, It works for me on Ubuntu 14.04 too.
Latest toolchain

Swift version 3.0-dev (LLVM b361b0fc05, Clang 11493b0f62, Swift 24a0c3de75)
Target: x86_64-unknown-linux-gnu

[mxcl]

Probably would be fixed if you import func libc.fclose

[aciidgh]

I figured but weird that CI errors out where as nothing on local

[aciidgh]

@mxcl trigger CI please

[mxcl]

@swift-ci Please test

[aciidgh]

CI succeeded merging
