The Devel::Profile package is a Perl code profiler. This will collect information on the execution time of a Perl script and of the subs in that script. This information can be used to determine which subroutines are using the most time and which subroutines are being called most often.

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.

Dir::Project provides a way to locate a source-controlled directory (CVS, Subversion, Perforce, etc) using only the current working directory (cd). This prevents users from having to set other environment variables when they switch between areas, and allows scripts and such inside the directory to be executed without changing the user's PATH.

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.

ExtUtils::Command provides a number of utilities to replace common UNIX commands in Makefiles, etc. At present the list includes cp, rm_f, rm_rf, mv, cat, eqtime, mkpath, touch, test_f, test_d, chmod, and dos2unix. Also included is the companion module Shell::Command, which is a thin wrapper for ExtUtils::Command to provide cross-platform functions emulating common shell commands.

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::Assets is a tool for managing JavaScript and CSS assets in a (web) application. It allows you to "publish" assests in one place after having specified them in different parts of the application (e.g. throughout request and template processing phases).

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

Derived from MultiTail, this perl library makes it easy to tail a dynamic list of files and match/except lines using full regular expressions and even maintains their state locally. File::Tail::Multi will tail multiple files and return the records read to a Data Structure. The Data Structure can be processed by File::Tail::Multi functions.
