Petite Chez Scheme is a freely distributable interpreted version of Chez Scheme, a high-performance implementation of ANSI Scheme with numerous extensions. Petite Chez Scheme may be used as a run-time environment for compiled Chez Scheme applications or as a stand-alone Scheme system. With the exception that the compiler is not present, Petite Chez Scheme is completely compatible with Chez Scheme.
pftp allows you to send and receive files and directories recursively, send and receive standard input and ouput, filter your connection, set the net buffer size, set the bandwidth, send UDP datagrams unicasted, broadcasted, and multicasted (which is meant for AUDIO and VIDEO streaming), send data to another user and manage that data, perform a network test based on either UDP or TCP, and use optimized buffers for your Gigabit Ethernet links. pftp can start from command line, as a daemon, or by inetd. All features are supported for IPv4 and IPv6.
pdq is a direct replacement of lpr. Adding and configuring printers does not require root privilege. Jobs can be monitored through completion, job status can be checked *after* completion. Users can create custom command line options to set features such as tray selection, color mode, and print quality options. xpdq provides a graphical GTK based interface to simplify printer and option selection, and provides a wizard for printer installation.
Peachpit is an automated "tarpit" utility aimed at interfering with censorware spiders. Harmless to all other Web agents, peachpit identifies the spiders used by censorware makers from host/agent data, then bogs the spider down in recursive, sleep-laden page output. It can be grafted invisibly into an existing HTML document tree under Apache or comparable Webservers.
