|
|
111 | This module started as an interface to the uulib/uudeview library by Frank |
|
|
112 | Pilhofer that can be used to decode all kinds of usenet (and other) |
|
|
113 | binary messages. |
|
|
114 | |
|
|
115 | After upstream abondoned the project, the library was continuously bugfixed |
|
|
116 | and improved in this module, with major focuses on security fixes, |
|
|
117 | correctness and speed (that does not mean that this library is considered |
|
|
118 | safe with untrusted data, but it surely is safer than the original |
|
|
119 | uudeview). |
