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.

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.

HaXml is a suite of libraries and tools for
manipulating XML documents in Haskell. It
includes a parser, a pretty-printer, a validator,
a combinator library for transforming
documents, and converters for changing a
Haskell datatype into an XML DTD, and for
changing an XML DTD into a set of Haskell
datatypes. There are also tools for a query
language based on XQL.

HaskellDB is a combinator library for
expressing queries and other operations on
relational databases in a type safe and
declarative way. All the queries and
operations are completely expressed within
Haskell, and no embedded (SQL) commands
are required.

jvmbridge is a bridge to the Java virtual machine
via JNI for Haskell (and perhaps later other
functional languages).

Green Card is a foreign function interface
preprocessor for Haskell. It simplifies the task
of interfacing Haskell programs to external
libraries, which are normally exposed via C
interfaces.

The ListLike module provides a common interface to
the various Haskell types that are "list-like".
Predefined interfaces include standard Haskell
lists, Arrays, ByteStrings, and lazy ByteStrings.
Custom types can easily be made ListLike instances
as well. ListLike also provides for String-like
types, such as String and ByteString, for types
that support I/O, and for types that can handle
infinite lists.

log2rotate is designed for rotating backups with an optimal balance between retention and space usage. Instead of rotating backups using some fixed period such as daily, weekly, monthly, or yearly, it rotates backups using exponentially-growing periods. The exponential periods are based on the base 2 logarithm or squaring, depending on how you look at it.

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.

haskell-augeas is a Haskell FFI wrapper for the Augeas API.

CheckRDF is a tool, consisting of a shell script
and a Haskell program, for downloading RDF site
summaries and showing news in a text file and in
an HTML file. It is highly configurable.
