@title{top level document}

@include-section{subdir/some-section.scrbl}

@;{
when i try to build this document, i get an error that image.png isn't
found at the top level.  i would expect that scribble would look for it
in subdir/image.png and not just image.png.  can i make scribble look
image.png in subdir?  do i want to, or am i maybe not fully
understanding something about scribble document building process?

scribble top-level.scrbl
