This perl routine will take a prompt, a default response and a list of possible responses and deal with the user interface, (and the user!), by displaying the prompt, showing the default, and checking to be sure that the response is one of the legal choices.

Test::Bits provides a single subroutine, bits_is(), for testing binary data. This module is quite similar to Test::BinaryData and Test::HexString in concept. The difference is that this module shows failure diagnostics in a different way, and has a slightly different calling style. Depending on the nature of the data you're working with, this module may be easier to work with.

Diazo implements a Deliverance like language using a pure XSLT engine. With Diazo, you "compile" your theme and ruleset in one step, then use a superfast/ simple transform on each request thereafter. Alternatively, compile your theme during development, check it into Subversion, and not touch Diazo during deployment.

hgsubversion is an extension for Mercurial that allows using Mercurial as a Subversion client. At this point, hgsubversion is usable by users reasonably familiar with Mercurial as a VCS. It's not recommended to dive into hgsubversion as an introduction to Mercurial, since hgsubversion "bends the rules" a little and violates some of the typical assumptions of early Mercurial users.

CoffeeScript is a little language that compiles into JavaScript. Underneath all of those embarrassing braces and semicolons, JavaScript has always had a gorgeous object model at its heart. CoffeeScript is an attempt to expose the good parts of JavaScript in a simple way.

File::ShareDir::Install allows you to install read-only data files from a distribution. It is a companion module to File::ShareDir, which allows you to locate these files after installation. It is a port Module::Install::Share to ExtUtils::MakeMaker with the improvement of only installing the files you want; .svn and other source-control junk will be ignored.

A resolver library used to communicate with a name server to perform DNS queries, zone transfers, dynamic DNS updates, etc. Creates an object hierarchy from a DNS server response, which allows you to view all of the information given by the DNS server. It bypasses the system resolver library and communicates directly with the server.

This library implements a system by which 2 image files can be compared, using a variety of comparison methods. In general, those methods operate on the images on a pixel-by-pixel basis and reporting statistics or data based on color value comparisons.

Math::Expr parses mathematical expressions into a tree structure. The expressions may contain integers, real numbers, alphanumeric variable names, alphanumeric function names and most other characters might be used as operators. The operators can consist of multiple characters. The only limitation is that a variable or function name may not start on a digit, and not all chars are accepted in operation names.

RngStreams is a C implementation of a high-quality uniform random number generator that supports multiple "independent" streams of uniform random numbers.
