Summary description: Scary and creepy math symbols with AMS-LaTeX integration
Announcement text: ----------------------------------------------------------------------
The halloweenmath package originated from a question asked for enjoyment on TeX-LaTeX Stack Exchange http://tex.stackexchange.com by the user cfr (see http://tex.stackexchange.com/q/336768/69818); it defines a handful of commands for typesetting mathematical symbols of various kinds, ranging from large operators to extensible arrow-like relationsand growing arrow-like math accents, that all draw from the classic Halloween-related iconography (pumpkins, witches, ghosts, cats, and so on) while being, at the same time, seamlessly integrated within the rest of the mathematics produced by (AmS-)LaTeX.
