Ensemble is a toolkit for building reliable distributed applications. It has been available for free public release for over 3 years now and has been used in a number of commercial and research systems. Ensemble provides a library of protocols that can be used for quickly building complex distributed applications. An application registers 10 or so event handlers with Ensemble, and then the Ensemble protocols handle the details of reliably sending and receiving messages, transferring state, implementing security, detecting failures, and managing reconfigurations in the system.
The Env::Array Perl module permits the user to treat an environment variable like a regular Perl array. Array operations are implemented to use splitting and joining based on the specified delimiter. Great for environment variables like PATH. PLEASE NOTE: This module is OBSOLETE as of Perl 5.6.0. The author submitted a patch to Perl to implement this functionality in the core Perl Env.pm module and it was accepted for the 5.6.0 release.
