Ignoring "_index" is not an issue.
Files/folders with underscore prefix are considered hidden and are not treated.

This is handy if have "partials" files that are included by others and you don't want to convert them independently.
However, ircc if you setup the file "_index.adoc" in the build script, it should work.

PS: We should probably document that better.
