+-- Hack: dblatex normalises the name of the main input file using
+-- os.path.realpath, which means that if we're in a linked build tree,
+-- it find the real source files rather than the symlinks in our link
+-- tree. This is fine for the static sources, but it means it can't
+-- find the generated sources.
+-- We therefore also generate the main input file, so that it really
+-- is in the link tree, and thus dblatex can find everything.
