+AnyKernel 2.0 - Flashable Zip Template for Kernel Releases with Ramdisk Modifications
+by osm0sis @ xda-developers
+
+"AnyKernel is a template for an update.zip that can apply any kernel to any ROM, regardless of ramdisk." - Koush
+
+AnyKernel2 pushes the format even further by allowing kernel developers to modify the underlying ramdisk for kernel feature support easily using a number of included command methods along with properties and variables.
+
+A working script based on DirtyV Kernel for Galaxy Nexus (tuna) is included for reference.
+
+// Properties / Variables
+
+kernel.string=KernelName by YourName @ xda-developers
+do.devicecheck=1
+do.initd=1
+do.modules=1
+do.cleanup=1
+device.name1=maguro
+device.name2=toro
+device.name3=toroplus
+block=/dev/block/platform/omap/omap_hsmmc.0/by-name/boot;
+
+do.devicecheck=1 specified requires at least device.name1 to be present. This should match ro.product.device or ro.build.product for your device. There is support for up to 5 device.name# properties.
+
+do.initd=1 will create the init.d directory in /system/etc/init.d/ and apply 755 permissions.
+
+do.modules=1 will push the contents of the module directory to /system/lib/modules/ and apply 644 permissions.
+
+do.cleanup=0 will keep the zip from removing it's working directory in /tmp/anykernel - this can be useful if trying to debug in adb shell whether the patches worked correctly. 
+
+// Command Methods
+
+dump_boot
+backup_file <file>
+replace_string <file> <if search string> <original string> <replacement string>
+insert_line <file> <if search string> <before/after> <line match string> <inserted line>
+replace_line <file> <line replace string> <replacement line>
+remove_line <file> <line match string>
+prepend_file <file> <if search string> <patch file>
+append_file <file> <if search string> <patch file>
+replace_file <file> <permissions> <patch file>
+write_boot
+
+"if search string" is the string it looks for to decide whether it needs to add the tweak or not, so generally something to indicate the tweak already exists.
+
+Similarly, "line match string" and "line replace string" are the search strings that locate where the modification needs to be made for those commands.
+
+"before/after" requires you simply specify "before" or "after" for the placement of the inserted line, in relation to "line match string".
+
+You may also use ui_print "<text>" to write messages back to the recovery during the modification process.
+
+// Instructions
+
+1- Place zImage in the root (dtb should also go here for devices that require a custom one, both will fallback to the original if not included)
+2- Place any required ramdisk files in /ramdisk
+3- Place any required patch files (generally partial files which go with commands) in /patch
+4- Modify the anykernel.sh to add your kernel's name, boot partition location, permissions for included ramdisk files, and use methods for any required ramdisk modifications
+5- zip -r9 UPDATE-AnyKernel2.zip * -x README UPDATE-AnyKernel2.zip
+
+Not required, but any tweaks you can't hardcode into the source should be added with a bootscript.sh like is done in the example provided.
+
+
+Have fun!
