* Makefile: prepend "make clean" in lisp directory when compiling
Rationale: Emacs prefers the compiled lisp files even if the source is newer.
In case of circular dependencies or if the dependencies file is not correct,
the compiled files might not reflect the sources. Since there is no canonical
way to remove all compiled files which are stale (it can be hacked, but it is
really ugly), it seems more prudent to just always remove the compiled files
before starting the compilation. Most folks already already do that anyway.
* Makefile, lisp/Makefile, doc/Makefile: add target clean-install
to remove files in install-directories
* default.mk: add customization variable $(SED)
* doc/Makefile: do not remove dir while cleaning
* lisp/Makefile: use sed instead of perl to weave git-status into
org.el and ignore any errors while doing it. Keep git status in
$(GITSTATUS) to make it more clear what happens in the check.
* Makefile: use info function for output and call shell only once
* default.mk: add PDFTEX and RMR variables for customization
* lisp/Makefile: add target 'all' and create $(lispdir) if necessary
* maint-targets.mk: invoke sub-make for HTML manuals
* maint.mk: remove unsused VARIABLES
* targets.mk: invoke sub-make for ./doc and clean up some targets
* Makefile: add an optional include local.mk
* default.mk: install lisp files into org subfolder by default
* lisp/Makefile: new file to handle all make targets within lisp
* lisp/dependencies.mk: dependencies, should rather be auto-generated
* maint.mk: remove obsolete variable definitions
* targets.mk: hand off to sub-make in ./lisp, remove unused targets
* Makefile: declare phony targets, remove help text for install-info-debian
* default.mk: add variable for FIND and RM
* targets.mk, maint-targets.mk: shuffle targets to where they belong, declare
phony targets, work around a texi2dvi bug, use pattern rules, use targets for
dependencies instead of repeating them verbatim
* Makefile: just keep help target (now also default for no target)
and include all other parts from here.
* default.mk: user editable variables with their default values
* maint.mk: definitions by maintainer, should not be touched by user
* targets.mk: user callable targets
* maint-targets.mk: targets for maintenance, should not be called by user
* dependencies.mk: keep order during compile (could become auto-generated)
This is the first in a series of patches that restructures the Makefile to
achieve easier customization and separation of different concerns (mainly user
vs. maintenance of the distribution). This first patch simply establishes a
set of files without changing anything else to provide a clean starting point.
It uses GNU make extensions since Makefile already depends on GNU make anyway.
