You can do an input.withReader { reader -> ... } to have a buffered reader
on the input stream.
And with that reader, you can do reader.eachLine { String s -> ... } to
iterate over all the lines.
Last interesting nugget, there's also the class groovy.io.LineColumnReader
potentially, if you're interested in keeping track of the position (column
and line number) in the file.
