Most of PSPP, as well as this manual, was written by Ben Pfaff.  See Contacting the Author, for instructions on contacting the author.

The PSPP source code incorporates julcal10 originally written by Michael A. Covington and translated into C by Jim Van Zandt. The original package can be found in directory ftp://ftp.cdrom.com/pub/algorithms/c/julcal10.  The entire contents of that directory constitute the package.  The files actually used in PSPP are julcal.c and julcal.h.
