+### Usage
+
+To build dependencies for the current arch+OS:
+
+    make
+
+To build for another arch/OS:
+
+    make HOST=host-platform-triplet
+
+For example:
+
+    make HOST=x86_64-w64-mingw32 -j4
+
+A prefix will be generated that's suitable for plugging into Bitcoin's
+configure. In the above example, a dir named x86_64-w64-mingw32 will be
+created. To use it for Bitcoin:
+
+    ./configure --prefix=`pwd`/depends/x86_64-w64-mingw32
+
+Common `host-platform-triplets` for cross compilation are:
+
+- `i686-w64-mingw32` for Win32
+- `x86_64-w64-mingw32` for Win64
+- `x86_64-apple-darwin11` for MacOSX
+- `arm-linux-gnueabihf` for Linux ARM 32 bit
+- `aarch64-linux-gnu` for Linux ARM 64 bit
+
+No other options are needed, the paths are automatically configured.
+
+Dependency Options:
+The following can be set when running make: make FOO=bar
+
+    SOURCES_PATH: downloaded sources will be placed here
+    BASE_CACHE: built packages will be placed here
+    SDK_PATH: Path where sdk's can be found (used by OSX)
+    FALLBACK_DOWNLOAD_PATH: If a source file can't be fetched, try here before giving up
+    NO_QT: Don't download/build/cache qt and its dependencies
+    NO_WALLET: Don't download/build/cache libs needed to enable the wallet
+    NO_UPNP: Don't download/build/cache packages needed for enabling upnp
+    DEBUG: disable some optimizations and enable more runtime checking
+    HOST_ID_SALT: Optional salt to use when generating host package ids
+    BUILD_ID_SALT: Optional salt to use when generating build package ids
+
+If some packages are not built, for example `make NO_WALLET=1`, the appropriate
+options will be passed to bitcoin's configure. In this case, `--disable-wallet`.
+
+Additional targets:
+
+    download: run 'make download' to fetch all sources without building them
+    download-osx: run 'make download-osx' to fetch all sources needed for osx builds
+    download-win: run 'make download-win' to fetch all sources needed for win builds
+    download-linux: run 'make download-linux' to fetch all sources needed for linux builds

+This is a system of building and caching dependencies necessary for building Bitcoin. 
+There are several features that make it different from most similar systems:
+
+### It is designed to be builder and host agnostic
+
+In theory, binaries for any target OS/architecture can be created, from a
+builder running any OS/architecture. In practice, build-side tools must be
+specified when the defaults don't fit, and packages must be amended to work
+on new hosts. For now, a build architecture of x86_64 is assumed, either on
+Linux or OSX.
+
+### No reliance on timestamps
+
+File presence is used to determine what needs to be built. This makes the
+results distributable and easily digestable by automated builders.
+
+### Each build only has its specified dependencies available at build-time.
+
+For each build, the sysroot is wiped and the (recursive) dependencies are
+installed. This makes each build deterministic, since there will never be any
+unknown files available to cause side-effects.
+
+### Each package is cached and only rebuilt as needed.
+
+Before building, a unique build-id is generated for each package. This id
+consists of a hash of all files used to build the package (Makefiles, packages,
+etc), and as well as a hash of the same data for each recursive dependency. If
+any portion of a package's build recipe changes, it will be rebuilt as well as
+any other package that depends on it. If any of the main makefiles (Makefile, 
+funcs.mk, etc) are changed, all packages will be rebuilt. After building, the
+results are cached into a tarball that can be re-used and distributed.
+
+### Package build results are (relatively) deterministic.
+
+Each package is configured and patched so that it will yield the same
+build-results with each consequent build, within a reasonable set of
+constraints. Some things like timestamp insertion are unavoidable, and are
+beyond the scope of this system. Additionally, the toolchain itself must be
+capable of deterministic results. When revisions are properly bumped, a cached
+build should represent an exact single payload.
+
+### Sources are fetched and verified automatically
+
+Each package must define its source location and checksum. The build will fail
+if the fetched source does not match. Sources may be pre-seeded and/or cached
+as desired.
+
+### Self-cleaning
+
+Build and staging dirs are wiped after use, and any previous version of a
+cached result is removed following a successful build. Automated builders
+should be able to build each revision and store the results with no further
+intervention.

+Each recipe consists of 3 main parts: defining identifiers, setting build
+variables, and defining build commands.
+
+The package "mylib" will be used here as an example
+
+General tips:
+- mylib_foo is written as $(package)_foo in order to make recipes more similar.
+
+## Identifiers
+Each package is required to define at least these variables:
+
+    $(package)_version:
+    Version of the upstream library or program. If there is no version, a
+    placeholder such as 1.0 can be used.
+
+    $(package)_download_path:
+    Location of the upstream source, without the file-name. Usually http or
+    ftp.
+
+    $(package)_file_name:
+    The upstream source filename available at the download path.
+
+    $(package)_sha256_hash:
+    The sha256 hash of the upstream file
+
+These variables are optional:
+
+    $(package)_build_subdir:
+    cd to this dir before running configure/build/stage commands.
+    
+    $(package)_download_file:
+    The file-name of the upstream source if it differs from how it should be
+    stored locally. This can be used to avoid storing file-names with strange
+    characters.
+    
+    $(package)_dependencies:
+    Names of any other packages that this one depends on.
+    
+    $(package)_patches:
+    Filenames of any patches needed to build the package
+
+    $(package)_extra_sources:
+    Any extra files that will be fetched via $(package)_fetch_cmds. These are
+    specified so that they can be fetched and verified via 'make download'.
+
+
+## Build Variables:
+After defining the main identifiers, build variables may be added or customized
+before running the build commands. They should be added to a function called
+$(package)_set_vars. For example:
+
+    define $(package)_set_vars
+    ...
+    endef
+
+Most variables can be prefixed with the host, architecture, or both, to make
+the modifications specific to that case. For example:
+
+    Universal:     $(package)_cc=gcc
+    Linux only:    $(package)_linux_cc=gcc
+    x86_64 only:       $(package)_x86_64_cc = gcc
+    x86_64 linux only: $(package)_x86_64_linux_cc = gcc
+
+These variables may be set to override or append their default values.
+
+    $(package)_cc
+    $(package)_cxx
+    $(package)_objc
+    $(package)_objcxx
+    $(package)_ar
+    $(package)_ranlib
+    $(package)_libtool
+    $(package)_nm
+    $(package)_cflags
+    $(package)_cxxflags
+    $(package)_ldflags
+    $(package)_cppflags
+    $(package)_config_env
+    $(package)_build_env
+    $(package)_stage_env
+    $(package)_build_opts
+    $(package)_config_opts
+
+The *_env variables are used to add environment variables to the respective
+commands.
+
+Many variables respect a debug/release suffix as well, in order to use them for
+only the appropriate build config. For example:
+
+    $(package)_cflags_release = -O3
+    $(package)_cflags_i686_debug = -g
+    $(package)_config_opts_release = --disable-debug
+
+These will be used in addition to the options that do not specify
+debug/release. All builds are considered to be release unless DEBUG=1 is set by
+the user. Other variables may be defined as needed.
+
+## Build commands:
+
+  For each build, a unique build dir and staging dir are created. For example,
+  `work/build/mylib/1.0-1adac830f6e` and `work/staging/mylib/1.0-1adac830f6e`.
+
+  The following build commands are available for each recipe:
+
+    $(package)_fetch_cmds:
+    Runs from: build dir
+    Fetch the source file. If undefined, it will be fetched and verified
+    against its hash.
+
+    $(package)_extract_cmds:
+    Runs from: build dir
+    Verify the source file against its hash and extract it. If undefined, the
+    source is assumed to be a tarball.
+
+    $(package)_preprocess_cmds:
+    Runs from: build dir/$(package)_build_subdir
+    Preprocess the source as necessary. If undefined, does nothing.
+
+    $(package)_config_cmds:
+    Runs from: build dir/$(package)_build_subdir
+    Configure the source. If undefined, does nothing.
+
+    $(package)_build_cmds:
+    Runs from: build dir/$(package)_build_subdir
+    Build the source. If undefined, does nothing.
+
+    $(package)_stage_cmds:
+    Runs from: build dir/$(package)_build_subdir
+    Stage the build results. If undefined, does nothing.
+
+  The following variables are available for each recipe:
+    
+    $(1)_staging_dir: package's destination sysroot path
+    $(1)_staging_prefix_dir: prefix path inside of the package's staging dir
+    $(1)_extract_dir: path to the package's extracted sources
+    $(1)_build_dir: path where configure/build/stage commands will be run
+    $(1)_patch_dir: path where the package's patches (if any) are found
+
+Notes on build commands:
+
+For packages built with autotools, $($(package)_autoconf) can be used in the
+configure step to (usually) correctly configure automatically. Any
+$($(package)_config_opts) will be appended.
+
+Most autotools projects can be properly staged using:
+
+    $(MAKE) DESTDIR=$($(package)_staging_dir) install
