Rename search-path to source-registry, registry to grain-registry.
Extract ASDF implementation identifier from target, so we may use it later.

Some documentation update.
Tweak hello Makefile for ASDF 2.
re-Hush warning from registry.
Add require-asdf.

Give proper semantics to resolve-absolute-module-name and resolve-module-name.
Make the hello example work properly.
hello now uses the generate functionality to extract version from parent XCVB.
Have log-format do fresh-lines for you.
Make sure builds are only interned once.
Recognize that builds may be invalid because of inherited conflict.

* separated searched build registry from traversed grain registry.
* started a virtual-pathnames layer
* small farmer progress.

(feature implemented for geoff wozniak).
tests now work with clisp (they didn't???).
some docs.

also tiny progress on the farmer.

* start some test infrastructure for release
* make image mode the default in configure.mk, for the sake of CCL
* fix the forker package, bake a collection macro
* extract executable and image name from target lisp (when possible)
 in view of tthsum'ing it in the future.

Unhappily, XCVB somehow fails to run properly with it.

"xcvb show-builds" is deprecated command.

* ensure installation directories exist
* add module forms to every file
* fix nickname registration
* add an eval-when for compile-time functions
* add support for xcvb.mk in the main Makefile
* trivially tested the result

* lay groundwork for dependencies on arbitrary files
* make some internals more extensible
* documentation update

* fix driver regarding asdf, fix repl
* only register nicknames and asdf supersession for non-conflicted builds
* use build post-image as basis for pre-image of other build that depends on it first
* updated documentation, remove obsolete example

* plus some more preparation for ASDF superseding
* minor doc updates

* Doc update: Git repo has moved, etc.
* Beginning of support for BUILDs that actually supersede ASDF systems.
* New cool utility funcallf
* Fix .asd file

* a dependency may recursively create zero, one or more lisp commands for loading files
* actual file dependencies and commands are accumulated into an environment object

* add a BUILD file for xcvb
* adding infrastructure to better track dependencies in general case
* documentation update
* Re-start a Makefile backend

* created a branch for the v0.1 prototype, documented how to access it.
* rewrote the normalizing and processing of the dependency mini-language.
* separated source vs normalized dependencies in lisp-grain objects.
* compute the latter at the correct time.
* fixed brokenness in the example as these dependencies were normalized (yay!).
* made fullname canonicalization more robust.
* refactored name resolution, fixed broken cases, handle conflicts.
* compiling (if not working) static backend -- to be debugged.
* reworked the misnamed simple-interpreter utility into simple-dispatcher.
* in .asd, comment out files that are borked by the rewrite.
* egoboo: put my name first amongst authors claiming massive rewrite.

* depends-on slots need be initialized before the :after method kicks in.
* can't provide :fullname in parse-module-declaration, or gonna conflict with the specified one.
* detect registry conflicts when trying to resolve names
* stop pretending that packages can isolate xcvb-test from xcvb and then having
 to export symbols (with is not maintainable), import them hackishly (which breaks),
 or have to prefix them all (which sucks). Probably xcvb-static-backends won't survive either.
* small fixes to match previous checkins.

* identify little languages for dealing with dependencies -- dependencies-interpreter.lisp
* hush compiler notes for SBCL
* allow to name pre-images
* fullnames now use leading / to distinguished from unresolved relative names
* now resolving names into actual grains.
* many utilities, including a parser for CL formals
   (over-engineering at work - but how else to be able to portably get user-readable error messages?)
* various small tweaks.

Joyce Chen came and helped me get unblocked by walking her through the existing code
and the work I am doing on static-backends. Thanks!

For the working prototype, please use
	git checkout xcvb_0.11

In this commit:
* massive refactoring of internals according to the "grain" design in TODO.
* implementing search path and naming for multiple builds.
* Documentation update including slides for ILC'09.
