Good idea -- thanks for the PR!

Another thing that can be done for the usability is to improve the behavior when the first line is not well formatted (return a comprehensive output message). As I didn't know I you were still active, I didn't put too much energy in it (and I don't know Ruby).

I might look at this next time I try to update the wiktionary-based dictionaries. I can't recall running into any problems with the header lines last time, but the format may have changed since then.

If you could tell me which specific dictionaries you tried to use that gave you errors, it would be really helpful for implementing this.

I have generated en-fr and en-es dictionaries and none had any header.

Hope this helps

Thanks, that's really helpful! I'll try to regenerate the en-fr and en-es dictionaries when I have some time. It sounds like the format has changed, so the script definitely needs an update as well. In the meantime I'll create an issue for this so it's on the to do list.
