\H file argument set on the toplevel header, you must put it under the special _file input directory. For example:_file/path/to/myfile.txt.bigb= myfile.txt
{file}

= myfile.txt is arbitrary, as it can be fully inferred from the file path _file/path/to/myfile.txt.bigb. TODO add linting for it. Perhaps we should make adding a header be optional and auto-generate that header instead. But having at least an optional header is good as a way of being able to set header properties like tags.
