Type::Tiny::XS provides an XS boost for some of Type::Tiny's built-in type constraints. Type::Tiny::XS is not required for Type::Tiny, but provides a speed boost for some type checks if available.

UUID::Random generates random uuid strings. It does not satisfy any of the points listed in RFC 4122 but the default format. If you need RFC compliant UUID strings have a look at Data::UUID.

`VCS' is an API for abstracting access to all version control systems from Perl code. This is achieved in a similar fashion to the `DBI' suite of modules. It comes with example CVS and RCS wrappers.

TheSchwartz is a reliable job queue system. Your application can put jobs into the system, and your worker processes can pull jobs from the queue atomically to perform. Failed jobs can be left in the queue to retry later.

Thread::Apartment provides an apartment threading wrapper for Perl classes. "Apartment threading" is a method for isolating an object (or object hierarchy) in its own thread, and providing external interfaces via lightweight client proxy objects. This approach is especially valuable in the Perl threads environment, which doesn't provide a direct means of passing complex, nested structure objects between threads, and for non-threadsafe legacy object architectures, e.g., Perl/Tk. By using lightweight client proxy objects that implement the Thread::Queue::Queueable interface, with Thread::Queue::Duplex objects as the communication channel between client proxies and apartment threads (or between threads in general), a more thread-friendly OO environment is provided, ala Java, i.e., the ability to pass arbitrary objects between arbitrary threads. Thread::Apartment is a fundamental component of the PSiCHE framework (http://www.presicient.com/psiche).

Throwable is a role for classes that are meant to be thrown as exceptions to standard program flow. It is very simple and does only two things: saves any previous value for $@ and calls die $self.

Tie::FileLRUCache Provides a lightweight Least Recently Used cache of data via either an object or tied interface. Keys and data are both allowed to be references and objects as well as scalars. Requires 'Digest::SHA1' to be installed.

This is a perl module for dealing with time intervals. Among other things, this module can tell you the number of hours, minutes, and seconds elapsed between two dates.

The "forks" pragma allows a developer to use threads without having to have a threaded perl, or to even run 5.8.0 or higher. There were a number of goals that I am trying to reach with this implementation. The standard Perl 5.8.0 threads implementation is very memory consuming, which makes it basically impossible to use in a production environment, particularly with mod_perl and Apache. Because of the use of the standard Unix fork() capabilities, most operating systems will be able to use the Copy-On-Write (COW) memory sharing capabilities (whereas with the standard Perl 5.8.0 threads implementation, this is thwarted by the Perl interpreter cloning process that is used to create threads). The memory savings have been confirmed. You should be able to run threaded applications unchanged by simply making sure that the "forks" and "forks::shared" modules are loaded, e.g. by specifying them on the command line.

strictures turns on indirect checking only when it thinks it's running in a compilation (or pod coverage) test - though if this causes undesired behaviour this can be overriden by setting the PERL_STRICTURES_EXTRA environment variable.
