-# Contributing
-
-Thank you for considering to help out with the source code! We welcome 
-contributions from anyone on the internet, and are grateful for even the 
-smallest of fixes!
-
-If you'd like to contribute to go-ethereum, please fork, fix, commit and send a 
-pull request for the maintainers to review and merge into the main code base. If
-you wish to submit more complex changes though, please check up with the core 
-devs first on [our gitter channel](https://gitter.im/ethereum/go-ethereum) to 
-ensure those changes are in line with the general philosophy of the project 
-and/or get some early feedback which can make both your efforts much lighter as
-well as our review and merge procedures quick and simple.
-
-## Coding guidelines

- * Code must adhere to the official Go 
-[formatting](https://golang.org/doc/effective_go.html#formatting) guidelines 
-(i.e. uses [gofmt](https://golang.org/cmd/gofmt/)).
- * Code must be documented adhering to the official Go 
-[commentary](https://golang.org/doc/effective_go.html#commentary) guidelines.
- * Pull requests need to be based on and opened against the `master` branch.
- * Commit messages should be prefixed with the package(s) they modify.
-   * E.g. "eth, rpc: make trace configs optional"
-
-## Can I have feature X
-
-Before you submit a feature request, please check and make sure that it isn't 
-possible through some other means. The JavaScript-enabled console is a powerful 
-feature in the right hands. Please check our

-
-  If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
-  To do so, attach the following notices to the program.  It is safest
-to attach them to the start of each source file to most effectively
-state the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.

+Package cl provides a binding to the OpenCL api. It's mostly a low-level
+wrapper that avoids adding functionality while still making the interface
+a little more friendly and easy to use.
+
+Resource life-cycle management:
+
+For any CL object that gets created (buffer, queue, kernel, etc..) you should
+call object.Release() when finished with it to free the CL resources. This
+explicitely calls the related clXXXRelease method for the type. However,
+as a fallback there is a finalizer set for every resource item that takes
+care of it (eventually) if Release isn't called. In this way you can have
+better control over the life cycle of resources while having a fall back
+to avoid leaks. This is similar to how file handles and such are handled
+in the Go standard packages.

+# cli.go
+`cli.go` is simple, fast, and fun package for building command line apps in Go. The goal is to enable developers to write fast and distributable command line applications in an expressive way.
+
+## Overview
+Command line apps are usually so tiny that there is absolutely no reason why your code should *not* be self-documenting. Things like generating help text and parsing command flags/options should not hinder productivity when writing a command line app.
+
+**This is where `cli.go` comes into play.** `cli.go` makes command line programming fun, organized, and expressive!
+
+## Installation
+Make sure you have a working Go environment (go 1.1+ is *required*). [See the install instructions](http://golang.org/doc/install.html).
+
+To install `cli.go`, simply run:
+```
+$ go get github.com/codegangsta/cli
+```
+
+Make sure your `PATH` includes to the `$GOPATH/bin` directory so your commands can be easily used:
+```
+export PATH=$PATH:$GOPATH/bin
+```
+
+## Getting Started
+One of the philosophies behind `cli.go` is that an API should be playful and full of discovery. So a `cli.go` app can be as little as one line of code in `main()`. 
+
+``` go
+package main
+
+import (
+  "os"
+  "github.com/codegangsta/cli"
+)
+
+func main() {
+  cli.NewApp().Run(os.Args)
+}
+```
+
+This app will run and show help text, but is not very useful. Let's give an action to execute and some help documentation:
+
+``` go
+package main
+
+import (
+  "os"
+  "github.com/codegangsta/cli"
+)
+
+func main() {
+  app := cli.NewApp()
+  app.Name = "boom"
+  app.Usage = "make an explosive entrance"
+  app.Action = func(c *cli.Context) {
+    println("boom! I say!")
+  }
+  
+  app.Run(os.Args)
+}
+```
+
+Running this already gives you a ton of functionality, plus support for things like subcommands and flags, which are covered below.
+
+## Example
+
+Being a programmer can be a lonely job. Thankfully by the power of automation that is not the case! Let's create a greeter app to fend off our demons of loneliness!
+
+Start by creating a directory named `greet`, and within it, add a file, `greet.go` with the following code in it:
+
+``` go
+package main
+
+import (
+  "os"
+  "github.com/codegangsta/cli"
+)
+
+func main() {
+  app := cli.NewApp()
+  app.Name = "greet"
+  app.Usage = "fight the loneliness!"
+  app.Action = func(c *cli.Context) {
+    println("Hello friend!")
+  }
+
+  app.Run(os.Args)
+}
+```
+
+Install our command to the `$GOPATH/bin` directory:
+
+```
+$ go install
+```
+
+Finally run our new command:
+
+```
+$ greet
+Hello friend!
+```
+
+`cli.go` also generates neat help text:
+
+```
+$ greet help
+NAME:
+    greet - fight the loneliness!
+
+USAGE:
+    greet [global options] command [command options] [arguments...]
+
+VERSION:
+    0.0.0
+
+COMMANDS:
+    help, h  Shows a list of commands or help for one command
+
+GLOBAL OPTIONS
+    --version	Shows version information
+```
+
+### Arguments
+You can lookup arguments by calling the `Args` function on `cli.Context`.
+
+``` go
+...
+app.Action = func(c *cli.Context) {
+  println("Hello", c.Args()[0])
+}
+...
+```
+
+### Flags
+Setting and querying flags is simple.
+``` go
+...
+app.Flags = []cli.Flag {
+  cli.StringFlag{
+    Name: "lang",
+    Value: "english",
+    Usage: "language for the greeting",
+  },
+}
+app.Action = func(c *cli.Context) {
+  name := "someone"
+  if len(c.Args()) > 0 {
+    name = c.Args()[0]
+  }
+  if c.String("lang") == "spanish" {
+    println("Hola", name)
+  } else {
+    println("Hello", name)
+  }
+}
+...
+```
+
+See full list of flags at http://godoc.org/github.com/codegangsta/cli
+
+#### Alternate Names
+
+You can set alternate (or short) names for flags by providing a comma-delimited list for the `Name`. e.g.
+
+``` go
+app.Flags = []cli.Flag {
+  cli.StringFlag{
+    Name: "lang, l",
+    Value: "english",
+    Usage: "language for the greeting",
+  },
+}
+```
+
+That flag can then be set with `--lang spanish` or `-l spanish`. Note that giving two different forms of the same flag in the same command invocation is an error.
+
+#### Values from the Environment
+
+You can also have the default value set from the environment via `EnvVar`.  e.g.
+
+``` go
+app.Flags = []cli.Flag {
+  cli.StringFlag{
+    Name: "lang, l",
+    Value: "english",
+    Usage: "language for the greeting",
+    EnvVar: "APP_LANG",
+  },
+}
+```
+
+The `EnvVar` may also be given as a comma-delimited "cascade", where the first environment variable that resolves is used as the default.
+
+``` go
+app.Flags = []cli.Flag {
+  cli.StringFlag{
+    Name: "lang, l",
+    Value: "english",
+    Usage: "language for the greeting",
+    EnvVar: "LEGACY_COMPAT_LANG,APP_LANG,LANG",
+  },
+}
+```
+
+### Subcommands
+
+Subcommands can be defined for a more git-like command line app.
+```go
+...
+app.Commands = []cli.Command{
+  {
+    Name:      "add",
+    Aliases:     []string{"a"},
+    Usage:     "add a task to the list",
+    Action: func(c *cli.Context) {
+      println("added task: ", c.Args().First())
+    },
+  },
+  {
+    Name:      "complete",
+    Aliases:     []string{"c"},
+    Usage:     "complete a task on the list",
+    Action: func(c *cli.Context) {
+      println("completed task: ", c.Args().First())
+    },
+  },
+  {
+    Name:      "template",
+    Aliases:     []string{"r"},
+    Usage:     "options for task templates",
+    Subcommands: []cli.Command{
+      {
+        Name:  "add",
+        Usage: "add a new template",
+        Action: func(c *cli.Context) {
+            println("new task template: ", c.Args().First())
+        },
+      },
+      {
+        Name:  "remove",
+        Usage: "remove an existing template",
+        Action: func(c *cli.Context) {
+          println("removed task template: ", c.Args().First())
+        },
+      },
+    },
+  },
+}
+...
+```
+
+### Bash Completion
+
+You can enable completion commands by setting the `EnableBashCompletion`
+flag on the `App` object.  By default, this setting will only auto-complete to
+show an app's subcommands, but you can write your own completion methods for
+the App or its subcommands.
+```go
+...
+var tasks = []string{"cook", "clean", "laundry", "eat", "sleep", "code"}
+app := cli.NewApp()
+app.EnableBashCompletion = true
+app.Commands = []cli.Command{
+  {
+    Name:  "complete",
+    Aliases: []string{"c"},
+    Usage: "complete a task on the list",
+    Action: func(c *cli.Context) {
+       println("completed task: ", c.Args().First())
+    },
+    BashComplete: func(c *cli.Context) {
+      // This will complete if no args are passed
+      if len(c.Args()) > 0 {
+        return
+      }
+      for _, t := range tasks {
+        fmt.Println(t)
+      }
+    },
+  }
+}
+...
+```
+
+#### To Enable
+
+Source the `autocomplete/bash_autocomplete` file in your `.bashrc` file while
+setting the `PROG` variable to the name of your program:
+
+`PROG=myprogram source /.../cli/autocomplete/bash_autocomplete`
+
+#### To Distribute
+
+Copy `autocomplete/bash_autocomplete` into `/etc/bash_completion.d/` and rename
+it to the name of the program you wish to add autocomplete support for (or
+automatically install it there if you are distributing a package). Don't forget
+to source the file to make it active in the current shell.
+
+```
+   sudo cp src/bash_autocomplete /etc/bash_completion.d/<myprogram>
+   source /etc/bash_completion.d/<myprogram>
+```
+
+Alternatively, you can just document that users should source the generic
+`autocomplete/bash_autocomplete` in their bash configuration with `$PROG` set
+to the name of their program (as above).
+
+## Contribution Guidelines
+Feel free to put up a pull request to fix a bug or maybe add a feature. I will give it a code review and make sure that it does not break backwards compatibility. If I or any other collaborators agree that it is in line with the vision of the project, we will work with you to get the code into a mergeable state and merge it into the master branch.
+
+If you have contributed something significant to the project, I will most likely add you as a collaborator. As a collaborator you are given the ability to merge others pull requests. It is very important that new code does not break existing code, so be careful about what code you do choose to merge. If you have any questions feel free to link @codegangsta to the issue in question and we can review it together.
+
+If you feel like you have contributed to the project but have not yet been added as a collaborator, I probably forgot to add you. Hit @codegangsta up over email and we will get it figured out.

+Package spew implements a deep pretty printer for Go data structures to aid in
+debugging.
+
+A quick overview of the additional features spew provides over the built-in
+printing facilities for Go data types are as follows:
+
+	* Pointers are dereferenced and followed
+	* Circular data structures are detected and handled properly
+	* Custom Stringer/error interfaces are optionally invoked, including
+	  on unexported types
+	* Custom types which only implement the Stringer/error interfaces via
+	  a pointer receiver are optionally invoked when passing non-pointer
+	  variables
+	* Byte arrays and slices are dumped like the hexdump -C command which
+	  includes offsets, byte values in hex, and ASCII output (only when using
+	  Dump style)
+
+There are two different approaches spew allows for dumping Go data structures:
+
+	* Dump style which prints with newlines, customizable indentation,
+	  and additional debug information such as types and all pointer addresses
+	  used to indirect to the final value
+	* A custom Formatter interface that integrates cleanly with the standard fmt
+	  package and replaces %v, %+v, %#v, and %#+v to provide inline printing
+	  similar to the default %v while providing the additional functionality
+	  outlined above and passing unsupported format verbs such as %x and %q
+	  along to fmt
+
+Quick Start
+
+This section demonstrates how to quickly get started with spew.  See the
+sections below for further details on formatting and configuration options.
+
+To dump a variable with full newlines, indentation, type, and pointer
+information use Dump, Fdump, or Sdump:
+	spew.Dump(myVar1, myVar2, ...)
+	spew.Fdump(someWriter, myVar1, myVar2, ...)
+	str := spew.Sdump(myVar1, myVar2, ...)
+
+Alternatively, if you would prefer to use format strings with a compacted inline
+printing style, use the convenience wrappers Printf, Fprintf, etc with
+%v (most compact), %+v (adds pointer addresses), %#v (adds types), or
+%#+v (adds types and pointer addresses):
+	spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2)
+	spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
+	spew.Fprintf(someWriter, "myVar1: %v -- myVar2: %+v", myVar1, myVar2)
+	spew.Fprintf(someWriter, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
+
+Configuration Options
+
+Configuration of spew is handled by fields in the ConfigState type.  For
+convenience, all of the top-level functions use a global state available
+via the spew.Config global.
+
+It is also possible to create a ConfigState instance that provides methods
+equivalent to the top-level functions.  This allows concurrent configuration
+options.  See the ConfigState documentation for more details.
+
+The following configuration options are available:
+	* Indent
+		String to use for each indentation level for Dump functions.
+		It is a single space by default.  A popular alternative is "\t".
+
+	* MaxDepth
+		Maximum number of levels to descend into nested data structures.
+		There is no limit by default.
+
+	* DisableMethods
+		Disables invocation of error and Stringer interface methods.
+		Method invocation is enabled by default.
+
+	* DisablePointerMethods
+		Disables invocation of error and Stringer interface methods on types
+		which only accept pointer receivers from non-pointer variables.
+		Pointer method invocation is enabled by default.
+
+	* ContinueOnMethod
+		Enables recursion into types after invoking error and Stringer interface
+		methods. Recursion after method invocation is disabled by default.
+
+	* SortKeys
+		Specifies map keys should be sorted before being printed. Use
+		this to have a more deterministic, diffable output.  Note that
+		only native types (bool, int, uint, floats, uintptr and string)
+		and types which implement error or Stringer interfaces are
+		supported with other types sorted according to the
+		reflect.Value.String() output which guarantees display
+		stability.  Natural map order is used by default.
+
+	* SpewKeys
+		Specifies that, as a last resort attempt, map keys should be
+		spewed to strings and sorted by those strings.  This is only
+		considered if SortKeys is true.
+
+Dump Usage
+
+Simply call spew.Dump with a list of variables you want to dump:
+
+	spew.Dump(myVar1, myVar2, ...)
+
+You may also call spew.Fdump if you would prefer to output to an arbitrary
+io.Writer.  For example, to dump to standard error:
+
+	spew.Fdump(os.Stderr, myVar1, myVar2, ...)
+
+A third option is to call spew.Sdump to get the formatted output as a string:
+
+	str := spew.Sdump(myVar1, myVar2, ...)
+
+Sample Dump Output
+
+See the Dump example for details on the setup of the types and variables being
+shown here.
+
+	(main.Foo) {
+	 unexportedField: (*main.Bar)(0xf84002e210)({
+	  flag: (main.Flag) flagTwo,
+	  data: (uintptr) <nil>
+	 }),
+	 ExportedField: (map[interface {}]interface {}) (len=1) {
+	  (string) (len=3) "one": (bool) true
+	 }
+	}
+
+Byte (and uint8) arrays and slices are displayed uniquely like the hexdump -C
+command as shown.
+	([]uint8) (len=32 cap=32) {
+	 00000000  11 12 13 14 15 16 17 18  19 1a 1b 1c 1d 1e 1f 20  |............... |
+	 00000010  21 22 23 24 25 26 27 28  29 2a 2b 2c 2d 2e 2f 30  |!"#$%&'()*+,-./0|
+	 00000020  31 32                                             |12|
+	}
+
+Custom Formatter
+
+Spew provides a custom formatter that implements the fmt.Formatter interface
+so that it integrates cleanly with standard fmt package printing functions. The
+formatter is useful for inline printing of smaller data types similar to the
+standard %v format specifier.
+
+The custom formatter only responds to the %v (most compact), %+v (adds pointer
+addresses), %#v (adds types), or %#+v (adds types and pointer addresses) verb
+combinations.  Any other verbs such as %x and %q will be sent to the the
+standard fmt package for formatting.  In addition, the custom formatter ignores
+the width and precision arguments (however they will still work on the format
+specifiers not handled by the custom formatter).
+
+Custom Formatter Usage
+
+The simplest way to make use of the spew custom formatter is to call one of the
+convenience functions such as spew.Printf, spew.Println, or spew.Printf.  The
+functions have syntax you are most likely already familiar with:
+
+	spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2)
+	spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
+	spew.Println(myVar, myVar2)
+	spew.Fprintf(os.Stderr, "myVar1: %v -- myVar2: %+v", myVar1, myVar2)
+	spew.Fprintf(os.Stderr, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
+
+See the Index for the full list convenience functions.
+
+Sample Formatter Output
+
+Double pointer to a uint8:
+	  %v: <**>5
+	 %+v: <**>(0xf8400420d0->0xf8400420c8)5
+	 %#v: (**uint8)5
+	%#+v: (**uint8)(0xf8400420d0->0xf8400420c8)5
+
+Pointer to circular struct with a uint8 field and a pointer to itself:
+	  %v: <*>{1 <*><shown>}
+	 %+v: <*>(0xf84003e260){ui8:1 c:<*>(0xf84003e260)<shown>}
+	 %#v: (*main.circular){ui8:(uint8)1 c:(*main.circular)<shown>}
+	%#+v: (*main.circular)(0xf84003e260){ui8:(uint8)1 c:(*main.circular)(0xf84003e260)<shown>}
+
+See the Printf example for details on the setup of variables being shown
+here.
+
+Errors
+
+Since it is possible for custom Stringer/error interfaces to panic, spew
+detects them and handles them internally by printing the panic information
+inline with the output.  Since spew is intended to provide deep pretty printing
+capabilities on structures, it intentionally does not return any errors.

+	  variables
+	* Byte arrays and slices are dumped like the hexdump -C command which
+	  includes offsets, byte values in hex, and ASCII output
+
+The configuration options are controlled by an exported package global,
+spew.Config.  See ConfigState for options documentation.
+
+See Fdump if you would prefer dumping to an arbitrary io.Writer or Sdump to
+get the formatted result as a string.

+standard fmt package for formatting.  In addition, the custom formatter ignores
+the width and precision arguments (however they will still work on the format
+specifiers not handled by the custom formatter).
+

+For details on this project, please see the Ethereum wiki:
+https://github.com/ethereum/wiki/wiki/Ethash
+
+### Coding Style for C++ code:
+
+Follow the same exact style as in [cpp-ethereum](https://github.com/ethereum/cpp-ethereum/blob/develop/CodingStandards.txt)
+
+### Coding Style for C code:
+
+The main thing above all is code consistency.
+
+- Tabs for indentation. A tab is 4 spaces
+- Try to stick to the [K&R](http://en.wikipedia.org/wiki/Indent_style#K.26R_style),
+  especially for the C code.
+- Keep the line lengths reasonable. No hard limit on 80 characters but don't go further
+  than 110. Some people work with multiple buffers next to each other.
+  Make them like you :)

+# -------------------

+#
+#
+# CMAKE_PARSE_ARGUMENTS(<prefix> <options> <one_value_keywords>
+# <multi_value_keywords> args...)
+#
+# CMAKE_PARSE_ARGUMENTS() is intended to be used in macros or functions
+# for parsing the arguments given to that macro or function.  It
+# processes the arguments and defines a set of variables which hold the
+# values of the respective options.
+#
+# The <options> argument contains all options for the respective macro,
+# i.e.  keywords which can be used when calling the macro without any
+# value following, like e.g.  the OPTIONAL keyword of the install()
+# command.
+#
+# The <one_value_keywords> argument contains all keywords for this macro
+# which are followed by one value, like e.g.  DESTINATION keyword of the
+# install() command.
+#
+# The <multi_value_keywords> argument contains all keywords for this
+# macro which can be followed by more than one value, like e.g.  the
+# TARGETS or FILES keywords of the install() command.
+#
+# When done, CMAKE_PARSE_ARGUMENTS() will have defined for each of the
+# keywords listed in <options>, <one_value_keywords> and
+# <multi_value_keywords> a variable composed of the given <prefix>
+# followed by "_" and the name of the respective keyword.  These
+# variables will then hold the respective value from the argument list.
+# For the <options> keywords this will be TRUE or FALSE.
+#
+# All remaining arguments are collected in a variable
+# <prefix>_UNPARSED_ARGUMENTS, this can be checked afterwards to see
+# whether your macro was called with unrecognized parameters.
+#
+# As an example here a my_install() macro, which takes similar arguments
+# as the real install() command:
+#
+# ::
+#
+#    function(MY_INSTALL)
+#      set(options OPTIONAL FAST)
+#      set(oneValueArgs DESTINATION RENAME)
+#      set(multiValueArgs TARGETS CONFIGURATIONS)
+#      cmake_parse_arguments(MY_INSTALL "${options}" "${oneValueArgs}"
+#                            "${multiValueArgs}" ${ARGN} )
+#      ...
+#
+#
+#
+# Assume my_install() has been called like this:
+#
+# ::
+#
+#    my_install(TARGETS foo bar DESTINATION bin OPTIONAL blub)
+#
+#
+#
+# After the cmake_parse_arguments() call the macro will have set the
+# following variables:
+#
+# ::
+#
+#    MY_INSTALL_OPTIONAL = TRUE
+#    MY_INSTALL_FAST = FALSE (this option was not used when calling my_install()
+#    MY_INSTALL_DESTINATION = "bin"
+#    MY_INSTALL_RENAME = "" (was not used)
+#    MY_INSTALL_TARGETS = "foo;bar"
+#    MY_INSTALL_CONFIGURATIONS = "" (was not used)
+#    MY_INSTALL_UNPARSED_ARGUMENTS = "blub" (no value expected after "OPTIONAL"
+#
+#
+#
+# You can then continue and process these variables.
+#
+# Keywords terminate lists of values, e.g.  if directly after a
+# one_value_keyword another recognized keyword follows, this is
+# interpreted as the beginning of the new option.  E.g.
+# my_install(TARGETS foo DESTINATION OPTIONAL) would result in
+# MY_INSTALL_DESTINATION set to "OPTIONAL", but MY_INSTALL_DESTINATION
+# would be empty and MY_INSTALL_OPTIONAL would be set to TRUE therefor.

+# FindPackageHandleStandardArgs
+# -----------------------------
+#
+#
+#
+# FIND_PACKAGE_HANDLE_STANDARD_ARGS(<name> ...  )
+#
+# This function is intended to be used in FindXXX.cmake modules files.
+# It handles the REQUIRED, QUIET and version-related arguments to
+# find_package().  It also sets the <packagename>_FOUND variable.  The
+# package is considered found if all variables <var1>...  listed contain
+# valid results, e.g.  valid filepaths.
+#
+# There are two modes of this function.  The first argument in both
+# modes is the name of the Find-module where it is called (in original
+# casing).
+#
+# The first simple mode looks like this:
+#
+# ::
+#
+#     FIND_PACKAGE_HANDLE_STANDARD_ARGS(<name>
+#       (DEFAULT_MSG|"Custom failure message") <var1>...<varN> )
+#
+# If the variables <var1> to <varN> are all valid, then
+# <UPPERCASED_NAME>_FOUND will be set to TRUE.  If DEFAULT_MSG is given
+# as second argument, then the function will generate itself useful
+# success and error messages.  You can also supply a custom error
+# message for the failure case.  This is not recommended.
+#
+# The second mode is more powerful and also supports version checking:
+#
+# ::
+#
+#     FIND_PACKAGE_HANDLE_STANDARD_ARGS(NAME
+#       [FOUND_VAR <resultVar>]
+#       [REQUIRED_VARS <var1>...<varN>]
+#       [VERSION_VAR   <versionvar>]
+#       [HANDLE_COMPONENTS]
+#       [CONFIG_MODE]
+#       [FAIL_MESSAGE "Custom failure message"] )
+#
+# In this mode, the name of the result-variable can be set either to
+# either <UPPERCASED_NAME>_FOUND or <OriginalCase_Name>_FOUND using the
+# FOUND_VAR option.  Other names for the result-variable are not
+# allowed.  So for a Find-module named FindFooBar.cmake, the two
+# possible names are FooBar_FOUND and FOOBAR_FOUND.  It is recommended
+# to use the original case version.  If the FOUND_VAR option is not
+# used, the default is <UPPERCASED_NAME>_FOUND.
+#
+# As in the simple mode, if <var1> through <varN> are all valid,
+# <packagename>_FOUND will be set to TRUE.  After REQUIRED_VARS the
+# variables which are required for this package are listed.  Following
+# VERSION_VAR the name of the variable can be specified which holds the
+# version of the package which has been found.  If this is done, this
+# version will be checked against the (potentially) specified required
+# version used in the find_package() call.  The EXACT keyword is also
+# handled.  The default messages include information about the required
+# version and the version which has been actually found, both if the
+# version is ok or not.  If the package supports components, use the
+# HANDLE_COMPONENTS option to enable handling them.  In this case,
+# find_package_handle_standard_args() will report which components have
+# been found and which are missing, and the <packagename>_FOUND variable
+# will be set to FALSE if any of the required components (i.e.  not the
+# ones listed after OPTIONAL_COMPONENTS) are missing.  Use the option
+# CONFIG_MODE if your FindXXX.cmake module is a wrapper for a
+# find_package(...  NO_MODULE) call.  In this case VERSION_VAR will be
+# set to <NAME>_VERSION and the macro will automatically check whether
+# the Config module was found.  Via FAIL_MESSAGE a custom failure
+# message can be specified, if this is not used, the default message
+# will be displayed.
+#
+# Example for mode 1:
+#
+# ::
+#
+#     find_package_handle_standard_args(LibXml2  DEFAULT_MSG
+#       LIBXML2_LIBRARY LIBXML2_INCLUDE_DIR)
+#
+#
+#
+# LibXml2 is considered to be found, if both LIBXML2_LIBRARY and
+# LIBXML2_INCLUDE_DIR are valid.  Then also LIBXML2_FOUND is set to
+# TRUE.  If it is not found and REQUIRED was used, it fails with
+# FATAL_ERROR, independent whether QUIET was used or not.  If it is
+# found, success will be reported, including the content of <var1>.  On
+# repeated Cmake runs, the same message won't be printed again.
+#
+# Example for mode 2:
+#
+# ::
+#
+#     find_package_handle_standard_args(LibXslt
+#       FOUND_VAR LibXslt_FOUND
+#       REQUIRED_VARS LibXslt_LIBRARIES LibXslt_INCLUDE_DIRS
+#       VERSION_VAR LibXslt_VERSION_STRING)
+#
+# In this case, LibXslt is considered to be found if the variable(s)
+# listed after REQUIRED_VAR are all valid, i.e.  LibXslt_LIBRARIES and
+# LibXslt_INCLUDE_DIRS in this case.  The result will then be stored in
+# LibXslt_FOUND .  Also the version of LibXslt will be checked by using
+# the version contained in LibXslt_VERSION_STRING.  Since no
+# FAIL_MESSAGE is given, the default messages will be printed.
+#
+# Another example for mode 2:
+#
+# ::
+#
+#     find_package(Automoc4 QUIET NO_MODULE HINTS /opt/automoc4)
+#     find_package_handle_standard_args(Automoc4  CONFIG_MODE)
+#
+# In this case, FindAutmoc4.cmake wraps a call to find_package(Automoc4
+# NO_MODULE) and adds an additional search directory for automoc4.  Here
+# the result will be stored in AUTOMOC4_FOUND.  The following
+# FIND_PACKAGE_HANDLE_STANDARD_ARGS() call produces a proper
+# success/error message.

+# FIND_PACKAGE_MESSAGE(<name> "message for user" "find result details")
+#
+# This macro is intended to be used in FindXXX.cmake modules files.  It
+# will print a message once for each unique find result.  This is useful
+# for telling the user where a package was found.  The first argument
+# specifies the name (XXX) of the package.  The second argument
+# specifies the message to display.  The third argument lists details
+# about the find result so that if they change the message will be
+# displayed again.  The macro also obeys the QUIET argument to the
+# find_package command.
+#
+# Example:
+#
+# ::
+#
+#   if(X11_FOUND)
+#     FIND_PACKAGE_MESSAGE(X11 "Found X11: ${X11_X11_LIB}"
+#       "[${X11_X11_LIB}][${X11_INCLUDE_DIR}]")

+  This code have two main entry points:
+
+  1. The initCL(...)  function configures one or more OpenCL device
+     (for now only GPU) and loads the Ethash DAG onto device memory
+
+  2. The Search(...) function loads a Ethash nonce into device(s) memory and
+     executes the Ethash OpenCL kernel.
+
+  Throughout the code, we refer to "host memory" and "device memory".
+  For most systems (e.g. regular PC GPU miner) the host memory is RAM and
+  device memory is the GPU global memory (e.g. GDDR5).
