Turns dialog files into their audio output through espeak, in a recursive manner similar to GNU make.
usage: espeak-scripty <input> [<output>]
input can be a dialog file (format described later), or a folder to
recursively check for dialog files, only updating the output files if the
dialog file's timestamp is newer than the corresponding output file's. This
allows for efficient recompilation.
output should be a folder to create output folders in. If not specified, it
uses the current working directory. Each dialog file is turned into a
folder of the same name in the output directory - a file called Hilda.txt
will generate a folder called Hilda.txt, though it *is* a folder, despite
the extension. To output all generated lines to your speakers instead of
your filesystem, use "-" as the output.
