Devel-Declare-Parser is a higher-level API sitting on top of Devel::Declare. It is used by Devel::Declare::Exporter to simplify exporting of Devel::Declare magic. Writing custom parsers usualy only requires subclassing this module and overriding a couple methods.

Devel::TraceUse - Show the modules your program loads, recursively. An apparently simple program may load a lot of modules. That's useful, but sometimes you may wonder exactly which part of your program loads which module. Devel::TraceUse can analyze a program to see which part used which module.

The Exporter module implements an "import" method which allows a module to export functions and variables to its users' namespaces. Many modules use Exporter rather than implementing their own "import" method because Exporter provides a highly flexible interface, with an implementation optimised for the common case.

File::ExtAttr is a Perl module providing access to the extended attributes of the files. Extended attributes are metadata associated with a file. Examples are access control lists (ACLs) and other security parameters. But users can add their own key=value pairs. Extended attributes are supported by FreeBSD starting from version 5.

FcntlLock is a module to do file locking in an object oriented fashion using the fcntl(2) system call. This allows locks on parts of a file as well as on the whole file and overcomes some known problems with flock(2), on which Perls flock() function is based by default.

File::Flock is a wrapper around the flock() call. The only thing it does that is special is that it creates the lock file if the lock file does not already exist. It will also try to remove the lock file. This makes it a bit complicated. http://search.cpan.org/dist/File-BasicFlock

File::HomeDir::PathClass is just a wrapper around File::HomeDir methods, transforming their return value to Path::Class objects. This allows for easier usage of the value. Refer to File::HomeDir#METHODS for a list of which functions are supported. File::HomeDir::PathClass supports both original File::HomeDir interfaces.

It monitors files in a given directory (or set of directories), such as Apache log files in /var/log/httpd, and as the log files are written to, takes the changes and sends them to a running instance of the Scribe logging system.

This class simplifies the handling of keyword argument lists. It replaces Class::AutoClass::Args. See "DIFFERENCES FROM Class::AutoClass::Args" for a discussion of what's new. See Hash::AutoHash::Args::V0 for a subclass which is more compatible with the original.
