The \module{cgitb} module provides a special exception handler for CGI
scripts. Using this module, an exception raised and left uncaught in
a CGI script can be presented as colorized HTML in the user's Web
browser. The options to the \function{enable()} function can be used
to control whether the colorized traceback is presented and whether
the traceback is logged to a file for later analysis.
\begin{funcdesc}{enable}{\optional{display\optional{, logdir\optional{,
context}}}}
This function causes the \module{cgitb} module to take over the
interpreters default handling for exceptions that propogate out of
the top level of a script. The causes \module{cgitb} to set the
value of \code{\refmodule{sys}.excepthook}.
The optional argument \var{display} defaults to true and can be set
to false to suppress sending the traceback to the browser.
\var{logdir}, if given, should be a directory to cause tracebacks to
be written to files there; by default tracebacks will not be written
to files. \var{context} is the number of lines of context around
the offending line in a traceback display; this defaults to
\code{5}.
\end{funcdesc}
\begin{funcdesc}{handler}{\optional{info}}
This function handles an exception using the default settings. This
can be used when you've caught an exception and want to report it
using \module{cgitb}, but need to continue processing.
\end{funcdesc}
