Libsmi is a C library that allows network management applications to access SMI MIB module information through a well-defined API that hides the nasty details of locating and parsing SMIv1/v2 MIB modules. Libsmi supports exact and iterative retrieval functions for all major SMIv1, SMIv2, and SMIng constructs. Some tools allow SMI module queries, checks, dumps, extraction, and various conversions and code generation.

Scsh is a systems-programming environment for POSIX systems and Win32, embedded in the Scheme programming language. It includes a high-level process notation for writing shell-script like programs, with pipelines and redirections. Scsh additionally provides low-level access to POSIX primitives, plus important non-POSIX extensions such as sockets. Scsh is implemented on top of Scheme48, a portable bytecode implementation of Scheme. A number of user-contributed extensions are available, including an extensible HTTP and FTP server, a socket-level PostgreSQL interface, a programmable text formatting language, and a Postscript generation language.
AWK address collection is a collection of scripts to extract information from a loosely formatted address file. It currently allows you to lookup addresses and phone numbers, list category members, list birthdates and ICQ UINs, automatically create a ~/.micqrc file with all ICQ users, and ~/diary with birthday reminders from the address database. It can be extended very easily.
The Heirloom Toolchest is a collection of standard Unix utilities.
