+=item C<ThrowCodeError>
+
+This function is used when an internal check detects an error of some sort.
+This usually indicates a bug in Bugzilla, although it can occur if the user
+manually constructs urls without correct parameters.
+
+This function's behaviour is similar to C<ThrowUserError>, except that the
+template used to display errors is I<global/code-error.html.tmpl>. In addition
+if the hashref used as the optional second argument contains a key I<variables>
+then the contents of the hashref (which is expected to be another hashref) will
+be displayed after the error message, as a debugging aid.
+
+=item C<ThrowTemplateError>
+
+This function should only be called if a C<template-<gt>process()> fails.
+It tries another template first, because often one template being
+broken or missing doesn't mean that they all are. But it falls back to
+a print statement as a last-ditch error.
