bin/: Server/client build scripts These scripts allow the TAME compiler stack to be invoked naturally, rather than requiring the use of a Makefile today. This will not only allow users to more easily invoke the compiler, but will also allow us to invoke TAME naturally from Makefile and remove the klugery that has existed for so long. This users a server/client architecture in order to mitigate the startup cost of the JVM. More documentation will follow. Note that there are a bunch of symlinks in rater/---this is a transition step to allow the build to continue working as it did before, which relies on a directory structure that exists outside of this repository. This will be cleaned up in the future. * .gitignore (bin/dslc): Add ignore for generated file. * bin/dslc.in: New script to encapsulate Java invocation. * bin/tame: New script (client). * bin/tamed: New script (server). * configure.ac (JAVA_OPTS, DSLC_CLASSPATH, AUTOGENERATED): New variables for dslc.in.

Integrate new compilation scripts, remove cqueue and Makefile.2 This is a major step toward normalcy---removing the kluge of a build process that was causing so many issues. Rather than echoing all operations to a queue file before passing it off to dslc, the new build scripts in `bin/' are used to invoke tame normally, as needed. This solves all of the current issues with things not rebuilding when they should. And, as a bonus, tab completion on targets works. Sorry this took so long. There wasn't much motivation until we hired so many people that are suffering from this. This does a few major things, along with some miscellaneous others: - Invoke bin/tame directly; - Merge Makefile.2.in into Makefile.am; and - Fix up some targets. * build-aux/Makefile.2.in: Delete file. Mostly merged with Makefile.am. * build-aux/Makefile.am: Add a bunch of new targets and definitions from Makefile.2.in. Modify all that previously used .cqueue to now invoke `$(TAME)' directly. Remove miscellaneous targets for trying to proxy targets to Makefile.2. (saneout, _go): Remove definitions. (.NOTPARALLEL): Add to prevent parallel builds. (ui/program.expanded.xml)[.version.xml]: Remove dependency for now. (clean): Also clean generated PHP files. Follow symlinks to clean core. This is still incomplete (does not clean all rate table stuff). (suppliers.mk)[xmlo_cmd]: Remove. See `gen-make' and `gen-c1make'. (lvroot)[summary-html]: New dependency. (kill-tamed, tamed-die): New targets (former alias of latter) to kill tamed. * build-aux/gen-c1make: Generate `$(TAME)' invocation. * build-aux/gen-make: Likewise. Remove `xmlo_cmd' output. Ignore recursive `tame' symlink (this can be removed once we clean `rater/' up. * build-aux/m4/calcdsl.m4 (TAME): Update description to reflect that it should now be the path to `bin/tame'. Adjust `AC_CHECK_FILE' lines accordingly. (tame_needed_ver): Remove. We have been in the same repo as TAME itself for quite some time. Remove associated code. (AC_CONFIG_FILES): Remove `Makefile.2'. * src/current/src/com/lovullo/dslc/DslCompiler.java (_DslCompiler)[compile]: Perform validation prefore `compile' command rather than a separate `validate' step.

Integrate new compilation scripts, remove cqueue and Makefile.2 This is a major step toward normalcy---removing the kluge of a build process that was causing so many issues. Rather than echoing all operations to a queue file before passing it off to dslc, the new build scripts in `bin/' are used to invoke tame normally, as needed. This solves all of the current issues with things not rebuilding when they should. And, as a bonus, tab completion on targets works. Sorry this took so long.
