I have:

```julia
julia> using LightGraphs, GraphIO

julia> graph = loadgraph("gr.dot", "gr", DOTFormat())
ERROR: UndefVarError: DOT not defined
Stacktrace:
 [1] DOTFormat() at /home/paul/.julia/packages/GraphIO/IgxnP/src/deprecations.jl:29
 [2] top-level scope at REPL[40]:1
 [3] include_string(::Function, ::Module, ::String, ::String) at ./loading.jl:1088

```

I see `DOT` module in `GraphIO.jl` repository. How do I make it visible to Julia REPL?

**EDIT**

I also tried:

```julia
julia> using LightGraphs, GraphIO.DOT
ERROR: UndefVarError: DOT not defined

```

and

```julia
Test Summary: | Pass Total
GraphIO | 143 143
    Testing GraphIO tests passed 

```

There is one more package needed to make it work:

```julia
using LightGraphs, GraphIO, ParserCombinator

```
