Discussion of various parts of the design with jlam@, wiz@, tls@ and many other developers. Special thanks to David Maxwell for testing the initial prototype and finding some bugs with Coverity Prevent. Supported by Google's Summer of Code 2007 project. OK for import during the freeze: jlam@ From DESCR: pbulk is the modular bulk build framework for pkgsrc. This package contains: - pbulk-scan, a program to scan the entire pkgsrc tree or a list of directories therein for packages and dependencies. Distributed operation using a master/client mode is supported. - pbulk-resolve, a program to resolve the dependencies from the output of pbulk-scan - pbulk-build, the build scheduler. Distributed builds via TCP are supported. - bulkbuild and related scripts to implement full and limited bulk builds on top of those programs. The pbulk framework is considered experimental.
