* Other features we would like:
+** Create a category of errors called `process-error'
+ for some or all errors associated with using subprocesses.
+
+** Maybe reinterpret `parse-error' as a category of errors
+ and put some other errors under it.
+
** A function to check for customizable options that have been
set but not saved, and ask the user whether to save them.
