Description
DIMACS (or, rather, some extension of the official DIMACS) seems to be a fairly standard graph specification format. I especially see it for lists of graphs for computational challenge problems such as clique finding or chromatic number. Is this format supported by GraphIO.jl? If not, should I add it and submit a pull request?
There are examples and a description of the format here: https://mat.tepper.cmu.edu/COLOR02/
The format has a header starting with "p" that tells the number of vertices and edges, then lines starting with "e" giving the edges. Lines starting with "c" are comments, and there can be other data which could be ignored by a basic reader.

Research direction
Start by reading GraphIO.jl's existing format readers and their tests, then compare their entry points with the linked DIMACS description. Done means a reader handles the p, e, and c line forms, tolerates ignorable data as appropriate, and has coverage for the supplied graph structure.
