Medical pedigrees look like genealogical trees, but also have certain
interesting features.  Usually they are drawn by hand by medical
geneticists.  This is a cumbersome and time-consuming process.  Freely
available programs for drawing genealogies are not fully suitable for
this task because of the special format of medical pedigrees.

We discuss a package for drawing pedigrees based on pstricks.  The
information is input by geneticists in a spreadsheet; a Perl program
extracts it and calls TeX to produce the final output.
