Um, yes... the thing is that the DL format does not really have a formal
specification (at least we weren't able to find any) and the current DL parser
is based on guesstimates that we distilled from the DL examples on the
following page:

It looks like there is much more to the DL format that we can currently parse
from igraph. Feel free to add a bug report on
https://github.com/igraph/igraph/issues .
