"""Exceptions for bzr, and reporting of them.
19
There are 3 different classes of error:
21
* KeyboardInterrupt, and OSError with EPIPE - the program terminates
22
with an appropriate short message
24
* User errors, indicating a problem caused by the user such as a bad URL.
25
These are printed in a short form.
27
* Internal unexpected errors, including most Python builtin errors
28
and some raised from inside bzr. These are printed with a full
29
traceback and an invitation to report the bug.
19
31
Exceptions are caught at a high level to report errors to the user, and
20
32
might also be caught inside the program. Therefore it needs to be
21
33
possible to convert them to a meaningful string, and also for them to be
