The `PostProc` package was originally developed by Stefano Baroni, Stefano de Gironcoli, Andrea Dal Corso (SISSA), Paolo Giannozzi (Univ. Udine), and many others. We mention in particular:

- Yang Jiao, Elsebeth Schröder, Per Hyldgaard (Chalmers) for the `ppacf.x` code;
- Alberto Otero-de-la-Roza for the `pw2critic.x` utility;
- Junfeng Qiao for improvements to `plotband.x`;
- Olivia Pulci, Adriano Mosca Conte, Davide Grassano (RomaII) for the `pw2gw` utility;
- Cyrille Barreteau and Alexander Smogunov (CEA) for magnetic anisotropy with the Force Theorem in `projwfc.f90`;
- Andrea Benassi (SISSA) for the `epsilon` utility, Tae Yun Kim and Cheol-Hwan Park (Seoul National University) for fixes to it;
- Dmitry Korotin (Inst. Met. Phys. Ekaterinburg) for the `wannier_ham` utility;
- Georgy Samsonidze (Bosch Research) for the interface with the Berkeley GW code;
- The late Prof. Eyvaz Isaev for the Fermi Surface code;
- Natalie Holzwarth (WFU) for the PAW projection in code `projwfc.f90`;
- Takashi Koretsune and Florian Thoele (ETHZ) for noncollinear magnetisation support with USPP and PAW pseudopotentials in code `pw2wannier.f90`.
- Leopold Talirz (U.York) for extensions and fixes to `pp.x`.
