gvoice enables other GKrellM plugins to use the IBM ViaVoice functionality without requiring that it be there to install. With this plugin, it is quite simple to add voice messages into other GKrellM plugins. If the IBM software is not installed, the voice functionality simply won't work.
glogwatch is a GKrellM plugin that alllows the monitoring of an arbitrary file, such as /var/log/messages, or a SNORT alert file, for changes. Once a change is detected, a timer is displayed showing the elapsed time since the change occurred. The timer is reset and re-armed when the user clicks on the plugin to view the file.
CVM (Credential Validation Module) is a modular system for validating credentials and providing information about them, using either piped command execution, Unix sockets, or UDP as the data transport. It is designed to be simpler than other existing systems (like PAM and Courier's authentication modules) and yet adequately functional for the majority of tasks.
BitTorrent is a tool for copying files from one machine to another. FTP punishes sites for being popular. Since all uploading is done from one place, a popular site needs big iron and big bandwidth. With BitTorrent, clients automatically mirror files they download, making the publisher's burden almost nothing.
HTTP Fetcher is a small, robust, flexible library for downloading files via HTTP using the GET method. It's easy to use, but it also allows you to customize and manipulate your file requests through altering the User Agent, Referer, timeout, etc. The error reporting functions give you a simple, clean interface through which to obtain information about a problem. HTTP Fetcher is designed to let you retrieve files via HTTP quickly and easily without having to reinvent the wheel. From this base you can build interactive download tools (like fetch), site mirroring tools, Web spiders, or anything with a need to do HTTP GETs.
Socket++ library defines a family of C++ classes that can be used more effectively for using sockets than directly calling the underlying low-level system functions. One distinct advantage of Socket++ is that it has the same interface as that of the iostream so that the users can perform type-safe input/output.
