* Handle subdirectories (e.g., \input{foo/bar.tex}). We don't yet

Browse source 
handle relative paths to parent directories (../foo/bar.tex).  This
  can be handled as was done in
  https://svn.cs.uu.nl:12443/repos/trace/nix/trunk/make/lib/compile-c.sh.
  The `copy-includes.pl' script is generic (not LaTeX specific), so it
  should eventually replace most of compile-c.sh and any future
  builders that have to set up a tree of symlinks to simulate the
  original directory hierarchy of the sources.
