AnyDBM is a Haskell module that provides a generic infrastructure for supporting storage of hash-like items with String-to-String mappings. It can be used for in-memory or on-disk storage. Two simple backend drivers are included with this package: one that is RAM-only, and one that is persistent and disk-backed. The hdbc-anydbm package provides another driver which lets you use simple tables in any SQL database to provide a DBM-like interface. MissingPy also provides a Python driver which lets you use any Python anydbm driver under Haskell AnyDBM.
The ConfigFile module for Haskell works with configuration files in a standard format that is easy for the user to edit, easy for the programmer to work with, and yet remains powerful and flexible. It is inspired by, and is compatible with, Python's ConfigParser module. It uses files that resemble Windows .INI-style files, but with numerous improvements. ConfigFile provides simple calls to both read and write config files. It's possible to make a config file parsable by this module, the Unix shell, and make.
datapacker is a tool to group files by size such that they fill fixed-size containers (called "bins") using the minimum number of containers. This is useful, for instance, if you want to archive a number of files to CD or DVD, and want to organize them such that you use the minimum possible number of CDs or DVDs. In many cases, datapacker executes almost instantaneously. Of particular note, the hardlink action can be used to effectively copy data into bins without having to actually copy the data at all. datapacker is a tool in the traditional Unix style; it can be used in pipes and call other tools.
Debian From Scratch is really two related components in one. First, it's a live bootable CD image that is designed to provide a full-featured kernel and rescue environment. It includes filesystem tools, editors, C compilers, Python, Perl, and everything you need to manually install Debian on a new machine. On ix86 machines, Grub is used to boot directly from the CD. There is also a program that is used to create the DFS CD images. It is highly configurable and can be used to create other custom bootable CD or DVD images. You can include whatever kernel or packages you want.
HDBC provides an abstraction layer between Haskell programs and SQL relational databases. This lets you write database code once, in Haskell, and have it work with any number of backend SQL databases (MySQL, Oracle, PostgreSQL, ODBC-compliant databases, etc.) HDBC is modeled loosely on Perl's DBI interface, though it has also been influenced by Python's DB-API v2, JDBC in Java, and HSQL in Haskell.
hslogger is a logging framework for Haskell, roughly similar to Python's logging module. hpodder lets each log message have a priority and source be associated with it. The programmer can then define global handlers that route or filter messages based on the priority and source. hslogger also has a syslog handler built in.
The Internet Gopher Client is based on the UMN Gopher/Gopherd 2.3.1 code. Gopher is an Internet technology that predates the Web. It presents information as a virtual network-wide filesystem. Modern browsers such as Konqueror can display gopherspace as if it contained files on your local machine (trees, drag and drop, etc.), but the difference is that each file or folder in that tree may be on a different machine.
