## ==========[ QUICKSTART ]==========
## Thanks to the generosity of FatTire, dalingrin, and other CyanogenMod
## hackers, we are now able to enjoy this CyanogenMod 9 preview. This
## Makefile maintains an environment for compiling CyanogenMod for the
## Barnes & Noble NOOK Color. The shell scripts included are based on
## FatTire's instructions, which you are encouraged to read before you
## continue
##   <https://docs.google.com/document/d/19f7Z1rxJHa5grNlNFSkh7hQ0LmDOuPdKMQUg8HFiyzs/edit>
##
## And until FatTire says otherwise, please do NOT distribute the update
## packages that you generate. We're in education mode here, so let's
## learn together. We wouldn't want the public repository to close now,
## would we? :P
##
## By following these instructions and/or using this set of files, you
## proceed at your own risk. Under no circumstances would you hold
## FatTire or Jiang Yio responsible for any negative consequences.
##
## IF YOU ALREADY HAVE A WORKING ENVIRONMENT IN ~/bin AND ~/android --
## This Makefile is for you, too. Just drop it in ~/android and do
##   make commonconfig
##   make init
## You also need to have rsync installed. There is no need to work from
## scratch.
##
## IF YOU ARE STARTING FROM THE BEGINNING --
## Firstly, create a directory where you want all the files to go.
## Then, put this file (Makefile) inside the directory, open a terminal
## window, and navigate to the directory.
##
## If you already have GNU Make, you could install the other required
## software on Debian/Ubuntu by running
##   sudo make apt
##
## Otherwise, you could install build-essential first, then see the
## previous paragraph. Alternatively, you could install the software
## yourself
##   git-core gnupg flex bison gperf libsdl1.2-dev libesd0-dev
##   libwxgtk2.6-dev squashfs-tools build-essential zip curl rsync
##   libncurses5-dev zlib1g-dev sun-java6-jdk pngcrush schedtool
## On 64-bit systems, you'd also need
##   g++-multilib lib32z1-dev lib32ncurses5-dev lib32readline6-dev
## On Ubuntu 10.10, you need to enable the partner repository for
## sun-java6-jdk
##   sudo add-apt-repository 'deb http://archive.canonical.com/ maverick partner'
##
## By default, this script tries to keep everything in your working
## directory. If you want the ~/bin and ~/android "standard", run
##   make commonconfig
##
## Now that you have all the required software, you could initialize
## your working directory
##   make init
##
## After answering a couple of questions, you should be ready to fetch
## the code. This takes a while, so it might be time to plan a nap or a
## coffee break. Wait for it
##   make sync
##
## Get out your NOOK Color and connect it to your computer using USB.
## You would now obtain some proprietary bits from your device
##   make vendor
## If you see errors, you might need to reconfigure adb. Perhaps an
## easier (but less secure) way is to start the adb service as root
##   sudo make adb
## and try again.
##
## You are now ready for the actual build process. This might take a few
## hours (depending on your hardware), so plan ahead:
##   make build
##
## That's it! You could now wipe your device and copy the files over,
## according to FatTire's tutorial, where $OUT is
##   system/out/target/product/encore
## and skip the next two paragraphs. Or, you could continue reading and
## make your own update.zip package.
##
## You would now make a snapshot, so you could roll back to an older
## build if you need to:
##   make snapshot
## This is actually required for the next step. The snapshots are
## incremental, so they don't use too much space unless there is a lot
## of new content. Since the feature is implemented using hard links, it
## is safe to remove any snapshot except for "current". Snapshots are
## stored within the snapshot directory.
##
## Then, simply build your package
##   make package CLEAN=1
## If you want a signed package, do
##   make package CLEAN=1 SIGN=1
## and if you want to package a snapshotted build, do something like
##   make package NAME=update-cm-9.0-encore-2011-12-19-00-54-13
## The options CLEAN, SIGN, and NAME may be combined in any way.
##
## To get the latest source code, simply sync
##   make sync
## and build
##   make build
##
## Good luck!
