-Overview of catalyst operation
-==============================
-
-* The program starts, and the local machine type is detected.
-
-* Based on this information, catalyst determines what kind of machine types
- it can build for (amd64 and ia64 can build for x86 as well, for example.)
- The appropriate arch plugins are loaded, which contain builder classes
- for each supported sub-arch.
-
-* Command-line arguments are parsed. If specified, a spec file is read.
-
-* These build variables are stored in an internal "spec" object, which will
- be a standard python dictionary. This spec dictionary contains all relevant
- build-related information.
-
-* The spec object is passed to the appropriate target constructor.
- The target constructor updates the spec object to contain data relevant
- to the particular target (stage1, stage3, grp, etc.)
-
-*** PROTOTYPE CODE UP TO HERE IS COMPLETE (drobbins, 26 Oct '03)
-
-* The full data of the spec object is written to disc, so there is a complete
- record of all variables that will be used to build what we're building. This
- will allow for another person to re-use this information to replicate our
- work (it should be possible to distribute a spec file along with a portage
- snapshot and a starter tarball, and our build can be replicated exactly on
- any machine.) The spec object contains data like CFLAGS, CHOST, subarch,
- mainarch, the profile used to build, and for GRP and LiveCDs the complete
- package build list. This is important to allow work to be replicated. It's
- possible that the stage1/2/3.sh and other scripts should be distributed as
- well, to allow proper replication of work.
-
-* The build process begins by calling the appropriate method of the builder
- instance. This includes cleanup, setup of chroot, entering the chroot,
- running the appropriate bash build script, checking for error conditions,
- and finishing up.
-
-* The catalyst process is now complete :)
