+Luke's AutoMake
+===============
+
+Yo, this document is incomplete. It describes the magical
+automake.{head,tail}.mk Makefiles and how to use them, kinda.
+
+I wrote a "clone" of automake. I say clone, because it works
+differently. Yeah, I need a new name for it.
+
+High-level overview
+-------------------
+
+Now, what this does for you is:
+
+It makes it _easy_ to write non-recursive Makefiles--and ones that are
+similar to plain recursive Makefiles, at that! (search for the paper
+"Recursive Make Considered Harmful") As harmful as recursive make is,
+it's historically been difficult to to write non-recursive Makefiles.
+This makes it easy.
+
+It also makes it easy to follow the GNU standards for your makefiles:
+it takes care of this entire table of .PHONY targets for you:
+
+| this | and this | are aliases for this |
+|------+------------------+--------------------------------------------------------|
+| all | build | $(outdir)/build |
+| | install | $(outdir)/install |
+| | uninstall | $(outdir)/uninstall |
+| | mostlyclean | $(outdir)/mostlyclean |
+| | clean | $(outdir)/clean |
+| | distclean | $(outdir)/distclean |
+| | maintainer-clean | $(outdir)/maintainer-clean |
+| | check | $(outdir)/check (not implemented for you) |
+| | dist | $(topoutdir)/$(PACKAGE)-$(VERSION).tar.gz (not .PHONY) |
+
+(You are still responsible for implementing the `$(outdir)/check`
+target in each of your Makefiles.)
+
+What you have to do is:
+
+In each source directory, you write a `Makefile`, very similarly to if
+you were writing for plain GNU Make, with
+
+ topoutdir ?= ...
+ topsrcdir ?= ...
+ include $(topsrcdir)/build-aux/Makefile.head.mk
+
+ # your makefile
+
+ include $(topsrcdir)/build-aux/Makefile.tail.mk
+
+And in the top-level source directory, Write your own helper makefiles
+that get included:
+ - `common.once.head.mk`: before parsing any of your Makefiles
+ - `common.each.head.mk`: before parsing each of your Makefiles
+ - `common.each.tail.mk`: after parsing each of your Makefiles
+ - `common.each.tail.mk`: after parsing all of your Makefiles
+
+The `common.*.mk` makefiles are nice for including generic pattern
+rules and variables that aren't specific to a directory.
+
+You're probably thinking that this sounds too good to be true!
+Unfortunately, there are two major deviations from writing a plain
+recursive Makefile:
+
+ 1. all targets and prerequisites (including .PHONY targets!) need to
+ be prefixed with
+ `$(srcdir)`/`$(outdir)`/`$(topsrcdir)`/`$(topoutdir)`.
+ * sub-gotcha: this means that if a pattern rule has a
+ prerequisite that may be in srcdir or outdir, then it must be
+ specified twice, once for each case.
+ 2. if a prerequisite is in a directory "owned" by another Makefile,
+ you must filter the pathname through `am_path`:
+ `$(call am_path,YOUR_PATH)`. Further, that path must NOT contain
+ a `..` segment; if you need to refer to a sibling directory, do it
+ relative to `$(topoutdir)` or `$(topsrcdir)`.
+
+Telling automake about your program
+-----------------------------------
+
+You tell automake what to do for you by setting some variables. They
+are all prefixed with `am_`; this prefix may be changed by editing the
+`_am` variable at the top of `automake.head.mk`.
+
+The exception to this is the `am_path` variable, which is a macro that
+is used to make a list of filenames relative to the appropriate
+directory, because unlike normal GNU (Auto)Make, `$(outdir)` isn't
+nescessarily equal to `.`. See above.
+
+There are several commands that generate files; simply record the list
+of files that each command generates as the following variable
+variables:
+
+| Variable | Create Command | Delete Command | Description | Relative to |
+|--------------+----------------+-----------------------------+-----------------------------------+-------------|
+| am_src_files | emacs | rm -rf . | Files that the developer writes | srcdir |
+| am_gen_files | ??? | make maintainer-clean | Files the developer compiles | srcdir |
+| am_cfg_files | ./configure | make distclean | Users' compile-time configuration | outdir |
+| am_out_files | make all | make mostlyclean/make clean | Files the user compiles | outdir |
+| am_sys_files | make install | make uninstall | Files the user installs | DESTDIR |
+
+In addition, there are two more variables that control not how files
+are created, but how they are deleted:
+
+| Variable | Affected command | Description | Relative to |
+|----------------+------------------+------------------------------------------------+-------------|
+| am_clean_files | make clean | A list of things to `rm` in addition to the | outdir |
+| | | files in `$(am_out_files)`. (Example: `*.o`) | |
+|----------------+------------------+------------------------------------------------+-------------|
+| am_slow_files | make mostlyclean | A list of things that (as an exception) should | outdir |
+| | | _not_ be deleted. (otherwise, `mostlyclean` | |
+| | | is the same as `clean`) | |
+
+Finally, there are two variables that express the relationships
+between directories:
+
+| Variable | Description |
+|------------+---------------------------------------------------------|
+| am_subdirs | A list of other directories (containing Makefiles) that |
+| | may be considered "children" of this |
+| | directory/Makefile; building a phony target in this |
+| | directory should also build it in the subdirectory. |
+| | They are not necesarily actually subdirectories of this |
+| | directory in the filesystem. |
+|------------+---------------------------------------------------------|
+| am_depdirs | A list of other directories (containing Makefiles) that |
+| | contain or generate files that are dependencies of |
+| | targets in this directory. They are not necesarily |
+| | actually subdirectories of this directory in the |
+| | filesystem. Except for files that are dependencies of |
+| | files in this directory, things in the dependency |
+| | directory will not be built. |
+
+Tips, notes
+-----------
+
+I like to have the first (non-comment) line in a Makefile be:
+
+ include $(dir $(lastword $(MAKEFILE_LIST)))/../../config.mk
+
+(adjusting the number of `../` sequences as nescessary). Then, my
+(user-editable) `config.mk` is of the form:
+
+ ifeq ($(topsrcdir),)
+ topoutdir := $(patsubst %/,%,$(dir $(lastword $(MAKEFILE_LIST))))
+ topsrcdir := $(topoutdir)
+
+ # your configuration
+
+ endif
+
+If the package has a `./configure` script, then I have it modifiy
+topsrcdir as necessary, as well as modifying whatever other parts of
+the configuration. All of the configuration lives in `config.mk`;
+`./configure` doesn't modify any `Makefile`s, it just generates
+`config.mk`, and copies (or (sym?)link?) every `$(srcdir)/Makefile` to
+`$(outdir)/Makefile`.
