complexity – Computational complexity class names

Com­plex­ity is a LaTeX pack­age that de­fines com­mands to type­set Com­pu­ta­tional Com­plex­ity Classes such as $\P$ and $\NP$ (as well as hun­dreds of oth­ers). It also of­fers sev­eral op­tions in­clud­ing which font classes are type­set in and how many are de­fined (all of them or just the ba­sic, most com­monly used ones).
The pack­age has no de­pen­den­cies other than the stan­dard ifthen pack­age.
