using Pkg

# list all available packages:

#Pkg.available()

# install one package (e.g. [Calculus](https://github.com/johnmyleswhite/Calculus.jl)) and all its dependencies:

Pkg.add("Calculus")

# to list all installed packages

Pkg.installed()

# to update all packages to their newest version

Pkg.update()

# to use a package:

using Calculus

# will import all functions of that package into the current namespace, so that

# it is possible to call

derivative(x -> sin(x), 1.0)

# without specifing the package it is included in.

import Calculus

# will enable you to specify which package the function is called from

Calculus.derivative(x -> cos(x), 1.0)

# Using `import` is especially useful if there are conflicts in function/type-names

# between packages.
