Utility for module developers to selectively reload needed modules and/or conditionally augment @INC with additional, per-developer library directories, at development time based on environment variables. Particularly helpful in conjunction with mod_perl applications where some or all application logic resides in separate Perl modules that would otherwise not get reloaded until the server restarts.

Module::CheckVersion checks latest version of modules with CPAN (or equivalent repo).

Module::Collect collects module files from some directories.

The functions exported by this module deal with runtime handling of Perl modules, which are normally handled at compile time.

This module provides a system for writing modules that *compile* other Perl modules. Modules that use these compilation modules get compiled into some altered form the first time they are run. The result is cached into ".pmc" files. Perl has native support for ".pmc" files. It always checks for them, before loading a ".pm" file.

Module::CoreList contains the hash of hashes %Module::CoreList::version, this is keyed on perl version as indicated in $]. The second level hash is module => version pairs. It also contains %Module::CoreList::released hash, which has ISO formatted versions of the release dates, as gleaned from the perlhist man page.

Module::Dependency - Collection of modules for examining dependencies between parents and children, like Perl files A set of pure-perl modules and helper programs that let you build a database of the dependency links between a collection of Perl files, and then query that database, even producing text, HTML, PostScript or graphical reports. The database in question is actually a simple Storable image of a Perl data structure, and you can create as many of these as you want. You can use the command-line tools, or write your own Perl to query and manipulate the data however you want.

Module::Depends extracts module dependencies from an unpacked distribution tree. Module::Depends only evaluates the META.yml shipped with a distribution. This won't be effective until all distributions ship META.yml files, so we suggest you take your life in your hands and look at Module::Depends::Intrusive.

Module::Extract is a convenience base class for creating module that work with Perl distributions. Its purpose is to take care of the mechanisms of locating and extracting a Perl distribution so that your module can do something specific to the distribution. This module was originally created to provide an abstraction for the extraction logic for both Module::Inspector and Module::P4P and to allow additional features to be added in the future without having to modify both of them, because the general problem of "locate, download, and expand a distribution" is one that is almost ideal for adding additional features down the line.

Module::ExtractUse is basically a Parse::RecDescent grammar to parse Perl code. It tries very hard to find all modules (whether pragmas, Core, or from CPAN) used by the parsed code.
