This package provides an implementation of "object interfaces" for Python. Interfaces are a mechanism for labeling objects as conforming to a given API or contract. So, this package can be considered as implementation of the Design By Contract methodology support in Python.

The zope.minmax.AbstractValue class provides a super class which can be subclassed to store arbitrary homogeneous values in a persistent storage and apply different conflict resolution policies. The subclasses defined here are resolving the conflicts using always either the maximum or the minimum of the conflicting values.

Launchy is helper class for launching cross-platform applications in a fire and forget manner. There are application concepts (browser, email client, etc) that are common across all platforms, and they may be launched differently on each platform. Launchy is here to make a common approach to launching external application from within ruby programs.

Liblogging offers an enhanced replacement for the syslog() call, but retains its ease of use. In a nutshell, it permits sytem administrators to direct application log output to different destinations without requiring the app developer to do any work for this. Liblogging is released under a 2-clause BSD license and as such can be used in any application.

Spin is an efficient on-the-fly verification system (a `model checker') for asynchronous concurrent systems, such as data communication protocols, distributed operating systems, database systems, etc. It can be used to prove both safety and liveness properties, including all correctness requirements expressible in linear time temporal logic. Spin uses a high level language to specify systems descriptions, called PROMELA (PROcess MEta LAnguage).

DNRD is a proxy DNS daemon. It supports several forward servers for redundancy and/or load-balancing. DNS queries for specific domains can be forwarded to a specific group of DNS servers (with redundancy and load balancing) for that domain. It is useful for VPNs and also good support for offline and dialup sites.

The Net::DNS::ZoneFile::Fast module provides an ability to parse zone files that BIND8 and BIND9 use, fast. Currently it provides a single function, parse(), which returns a reference to an array of traditional Net::DNS::RR objects, so that no new API has to be learned in order to manipulate zone records.

dhex is a more than just another hex editor: It includes a diff mode, which can be used to easily and conveniently compare two binary files. Since it is based on ncurses and is themeable, it can run on any number of systems and scenarios. With its utilization of search logs, it is possible to track changes in different iterations of files easily.

Hexedit view and edit files in hexadecimal or in ASCII. hexedit shows a file both in ASCII and in hexadecimal. The file can be a device as the file is not whole read. You can modify the file and search through it. You have also copy&paste, and save to file functions. Modifications are shown in bold.
