Invoking the Julia package manager can be done in either of two ways:
julia> using Pkg julia> Pkg.status() Status `~/.julia/environments/v1.0/Project.toml` [c5f51814] CUDAdrv v0.8.5 [91a5bcdd] Plots v0.19.2 julia>
or by using the interactive command-line invoked by typing the
julia> ] (v1.0) pkg> status Status `~/.julia/environments/v1.0/Project.toml` [c5f51814] CUDAdrv v0.8.5 [91a5bcdd] Plots v0.19.2 (v1.0) pkg>
You should definately read the package manager documentation as this covers some of the useful features of Julia for repoducible research using Project and Manifest files.
