This module handles the installing and uninstalling of perl modules, scripts, man pages, etc... Both install() and uninstall() are specific to the way ExtUtils::MakeMaker handles the installation and deinstallation of perl modules. They are not designed as general purpose tools.

"Joseki" is a japanese term from the game Go and means "a formulaic sequence of moves which is established for giving equal outcomes to both players", but it has come into general use to describe any fixed form of behaviour. Dist::Joseki offers you tools that help you in developing Perl module distributions if you stick to a certain formulaic style of structuring your distributions.

This module provides an easy interface for getting various metadata about a Perl module distribution.

Dist::Zilla builds distributions of code to be uploaded to the CPAN. In this respect, it is like ExtUtils::MakeMaker, Module::Build, or Module::Install. Unlike those tools, however, it is not also a system for installing code that has been downloaded from the CPAN. Since it's only run by authors, and is meant to be run on a repository checkout rather than on published, released code, it can do much more than those tools, and is free to make much more ludicrous demands in terms of prerequisites.

DynaLoader::Functions provides a function-based interface to dynamic loading as used by Perl. Some details of dynamic loading are very platform-dependent, so correct use of these functions requires the programmer to be mindful of the space of platform variations.

Error::Helper provides some easy error related methods.

String eval is often used for dynamic code generation. For instance, Moose uses it heavily, to generate inlined versions of accessors and constructors, which speeds code up at runtime by a significant amount. String eval is not without its issues however - it's difficult to control the scope it's used in (which determines which variables are in scope inside the eval), and it can be quite slow, especially if doing a large number of evals. This module attempts to solve both of those problems. It provides an eval_closure function, which evals a string in a clean environment, other than a fixed list of specified variables. It also caches the result of the eval, so that doing repeated evals of the same source, even with a different environment, will be much faster (but note that the description is part of the string to be evaled, so it must also be the same (or non-existent) if caching is to work properly).

Eval::LineNumbers adds a #line "this-file" 392 comment to hereis text that is going to be eval'd so that error messages will point back to the right place. Please note: when you embed \n in your code, it gets expanded in double-quote hereis documents so it will mess up your line numbering. Use \\n instead when you can.

Event::Join is a perl module to join multiple "events" into one.

The pkg-config program retrieves information about installed libraries, usually for the purposes of compiling against and linking to them. ExtUtils::PkgConfig is a very simplistic interface to this utility, intended for use in the Makefile.PL of perl extensions which bind libraries that pkg-config knows. It is really just boilerplate code that you would've written yourself.
