GParallel Edition
Details
Release Info
Physical frequency limits of currently-employed materials have been met some time ago. Multiple Cores were the natural answer, permitting ever-greater SMP execution. Applications were adapted to harness the benefits, however, countless cycles are still wasted, which is wasteful on any number of fronts. GNU Parallel and similar tools discourage waste by allowing more simultaneous executions. Have a proper glance at this simple, but powerful Executor in this release.Release Syllabus

Command-Sub Edition
Details
Release Info
Among the many useful $SHELL features is the ability to substitute commands in-place, at the calling-point. Command substitution places the output of one or more commands at your disposal for usage in say a Variable, Alias, or in-line for further processing. Nesting extends this functionality as far as your (use-case | imagination) dictates, possibly resulting in extremely useful time-saving command-sets. Spend some time substituting commands in this release.Release Syllabus
