dmassage uses the information in a BSD system's dmesg to gather information about the system's hardware devices and present this information in a tree-like hierarchy. This information can then be used to build a more efficient kernel that only contains support for devices that are actually present. It can also be used to disable probes for absent devices, thus speeding up the boot process.
Cyclone is a low-level network toolkit that provides support for HTTP 1.1 in an API very similar to the one implemented by the Tornado Web server. It has localization based on gettext with pluralization support, native support for XMLRPC and JSONRPC, native support for WebSockets (drafts 75 and 76), decent support for sending plain text or HTML email with TLS and attachments, built-in support for Redis, and support for HTTP authentication.
