+These packages provide useful definitions which I use often when writing
+scientific documents (and more specifically for quantum information theory).
+Some packages may be of more general use (formatting notes as a short document,

+Other packages are meant for scientific documents (more advanced theorems/proofs

 - `phfnote` - format documents for short notes.  Nicer title, saves more space

-- `phfparen` - cool definitions for mathematical parenthetic expressions.  Easy

 - `phffullpagefigure` - as the package name suggests, place figures on full pages.
   The caption e.g. reads "Figure 1 (on next page): blah blah" and the figure
