Reading DOT graph

Specific Domains Graphs

I have:

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

and

Test Summary: | Pass  Total
GraphIO       |  143    143

There is one more package needed to make it work:

using LightGraphs, GraphIO, ParserCombinator
