Try to make it work with gcl - but gcl fails to compile driver.lisp.

	settings known to xcvb or the individual value of a single one.
Change the default object-directory location to be
	$HOME/.cache/xcvb/common-lisp/<lisp-implementation-version>/
Added format! in driver.lisp to help with debugging and forcing output.
Debugged CMUCL support in driver.
Fixed implementation-identifier support in extract-target-properties.
Allowed Makefile in example-1 to parameterize on lisp implementation.
Refactored how option-specs are specified for command line options.
Removed dead code paths from simple-build backend that dealt with
	"xcvb.mk" and the makefile output file.
Muffled warnings when loading asdf.
Added target-asdf-version setting which you can query with show-settings.
Started DONE.rest

Added new unit test for slurping lines with an empty input.
Changed how TMP is used on unix in the call-with-temporary-file macro.

Add clisp .fas and .lib to gitignore

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.

* Fix output-path defaulting in asdf backend.
* Trivial refactorings in driver, alias rmx for remove-xcvb,
* Created XCVB hello, an example CL application using XCVB.
* Trivial test a2x-test for a2x and rmx
* Created a test suite -- itself still mostly untested.
* new checking function (still unused) in names
* More TODO items.

* start of a forker and farmer
* better error message when you forget to make your dependencies a list
* doc update

revealed by bootstrapping using ASDF; also release with a fixed cl-launch 2.29.

Complete the non-enforcing makefile backend.
Refactor a bit the asdf backend along the way.
Debug portablish-pathname, main.

Had to do a few things by hand to compile xcvb itself with poiu:
   mkdir obj-ne ; ln -s ../../poiu/poiu.asd obj-ne/ ;
   xcvb nm --build xcvb --parallel && make -f xcvb-ne.mk

Makefile creates xcvb-bootstrapped, which is a shell executable.

* make ASDF superseding work by properly refactoring the dependency-interpreter
* properly recurse on build targets
* record dependencies included in an image
* complete initial image creation
* debug the driver
* properly detect loaded asdf up-to-date status
* error when there are extension forms, for now
* add some verbosity mechanism
* add some trivial command-line interface
* actually use the command-line-arguments library (and debug its packaging)
* complete the mock test example, with a working Makefile!

Note: XCVB 0.300 depends on cl-launch 2.13.3 or later... to be released as 2.14 RSN.

* the Makefile itself is still untested, but XCVB now produces a Makefile that looks like it's work!
* support for building initial image from driver
* update to portablish pathnames
* update asdf frontend
* update mock test case
* debug command-line-arguments packaging
* small documentation update
* remove obsolete files extensions and traverse
* add trivial logging infrastructure
* change the way images are computed -- we can't allow name override anymore since the "name"
  serves as a pattern for how to compute the stuff.

* Fix name resolution to allow relative naming of BUILDs as well as files.
* Add load capability to lisp-invocation-arglist (to make it easy to load a driver).
* Documentation update, notably re: TODO items.

* Tweaks to the asdf converter and the way the first-file-form is read.
* Big update of the TODO file, including annotations of items with priorities.
* small update to the INTERNALs description and ilc09 presentation summary.
* Some utility functions to deal with pathnames somewhat portably.
* Renaming of string escaping functions, enhancement to with-output macro.

Still not working, but goes halfway towards the goal.

* Create a Makefile & configuration example.
* Yet another documentation revamp.
* Make sure it compiles without error (as for running -- still not tested, use xcvb_0.1)
