* Now with 87% more hot jail action! * Predeclared all C methods in jail.h, so they could be arranged in logical order in jail.c * Fixed the extconf namespace. * Added rdoc. * Added usage examples, demonstrating jls, jexec, and jail ruby equivalents. * Re-added the "attach and execute within a block" code. * Added Enumerable and Comparable support. * Return 'path' as a Pathname object. TODO: * Create the actual 'jParallel' shell binary, now that we have a good backend framework. * Tests? How? * Add support for recently committed (will be part of 7.2-RELEASE) multiple IPs per jail, and jail labels.
