 - Integrate pdf-tools.cc with the rest of the code
 - What if an input page specifies /Rotate?
-- Better error messages from instantiation
-- page->index: use or remove
+- "-f" switch
+- What should do modulo(half) with an odd number of tuples? Improve, or at least document.
+- Modulo with last tuple incomplete: sometimes, not padding the last tuple can be useful
+  (e.g., "flip every other page")
+- Document use of negative numbers in ranges
+- Allow use of page labels to refer to pages
+- Better range syntax for "from N to end" or "the whole document"
+- nup: allow stacking ("1 3 5 7" "2 4 6 8")

+Ideas for further commands:

+# Can be written as: mix(cat) { modulo(2){1}, modulo(2){2} }
+duplex
+       long-edge

+# Send pages to multiple pipes and merge their results
+mix { ..., ..., ...}
+       cat             # Concatenate results (default is interleave)
+       cycle           # When one pipe ends earlier, cycle it from start
+       pad             # When one pipe ends earlier, add blank pages
