[pstricks] ER Diagram Creation Example

[Rich Shepard]

   I need to prepare an ER (entity-relationship) diagram to illustrate the
relationships in a complex database schema. I wanted to examine the code and
results of an example, but the copy of latex pst-er.example.tex I have in
pst-dbicons won't compile. (It starts with \begin{landscape} and naturally
doesn't like that.)

   Please point me to some documentation for creating such a figure. I could
not find anything on the PSTricks examples pages.
