acbuild vendors its dependencies. This is done mostly with the glide tool, and glide-vc is used to strip unnecessary files from the dependencies.
These tools can be easily installed with a couple of go get commands.
go get github.com/Masterminds/glide
go get github.com/sgotti/glide-vc
This will fetch both tools, build them, and put the binaries in $GOPATH/bin.
glide get -s -u -v <package-name>
glide vc --only-code --no-tests
Edit the glide.yaml file in the repository, and then run:
glide up -s -u -v
glide vc --only-code --no-tests
glide rm --delete <package-name>
