Test-AutoBuild

This release adds support for checking out modules from GIT, Bazaar, Monotone, and Darcs SCM repositories.

The SCM checkout process is rewritten so that failures in checking out a module do not cause the entire build engine to abort. Failing modules are skipped and SCM logs made available for inspection on the HTML status pages. Other minor portability/stability bugfixes are included, in particular for portability to non-Linux platforms.

The backend build engine has been refactored into a modular workflow engine. Support for Mercurial SCM repos has been added, and existing SCM implementations extended to allow extraction of changelogs. Performance and scalability are improved by hard linking files instead of copying. Error reporting and logging has been enhanced to make debugging of crashes/problems simpler. Major work has been done on documentating the tools, configuration file format, and developer APIs. The coverage of the test suite has been increased to cover a large portion of the critical code sub-systems.

Bugs in the utility code for copying files into
the cache and publishing artifacts to the web root
were resolved. The HTML templates were updated to
include a graphical icon illustrating status. The
CSS templates were updated with a new primary
style to match official project styling. It now
has a requirement on the new Config::Record 1.1.0
release.

This release uses version 1.0.3 of the Config::Record module
for parsing configuration files and backported the new HTML
template generator from the development branch. This
included re-written HTML to comply with the HTML 4.0 strict
DTD and full use of CSS for theming. Also included was a
template to generate an RSS feed with summary of modules
built on the last cycle.
