This module should be used instead of the built-in module\code{pnl}\refbimodindex{pnl}to interface with the\emph{Panel Library}. The module is too large to document here in its entirety.One interesting function: \begin{funcdesc}{defpanellist}{filename}Parses a panel description file containing S-expressions written by the\emph{Panel Editor}that accompanies the Panel Library and creates the described panels.It returns a list of panel objects.\end{funcdesc} \warning{The Python interpreter will dump core if you don't create aGL window before calling\code{panel.mkpanel()}or\code{panel.defpanellist()}.} \section{\module{panelparser} ---         None}\declaremodule{standard}{panelparser} \modulesynopsis{None}  This module defines a self-contained parser for S-expressions as outputby the Panel Editor (which is written in Scheme so it can't help writingS-expressions).The relevant function is\code{panelparser.parse_file(\var{file})}which has a file object (not a filename!) as argument and returns a listof parsed S-expressions.Each S-expression is converted into a Python list, with atoms convertedto Python strings and sub-expressions (recursively) to Python lists.For more details, read the module file.% XXXXJH should be funcdesc, I think \section{\module{pnl} ---         None}\declaremodule{builtin}{pnl} \modulesynopsis{None}  This module provides access to the\emph{Panel Library}built by NASA Ames\index{NASA} (to get it, send email to\code{panel-request@nas.nasa.gov}).All access to it should be done through the standard module\code{panel}\refstmodindex{panel},which transparently exports most functions from\code{pnl}but redefines\code{pnl.dopanel()}. \warning{The Python interpreter will dump core if you don't create aGL window before calling \code{pnl.mkpanel()}.} The module is too large to document here in its entirety.
