rBuild 1.2.4 is a maintenance release.

• The "rbuild checkout" command now takes a "--factory=" option. Also, when checking out a package with a name that starts with "factory-" it is automatically set to be a factory. (RBLD-125)
• rBuild now logs all its actions and outputs to a .rbuild/log file either in the checkout (where possible) or under $HOME (otherwise). (RBLD-225)

• The "rbuild checkout --derive" command has been changed to match Conary changes, and will now work only with Conary 2.1.16 or later. (CNY-3348)
