+
+# 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.
+
+You can view the API docs here:
+http://godoc.org/github.com/codegangsta/cli
+
+## 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 some bitchass 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)
+  }
+}
+...
+```
+
+#### 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",
+    ShortName: "a",
+    Usage:     "add a task to the list",
+    Action: func(c *cli.Context) {
+      println("added task: ", c.Args().First())
+    },
+  },
+  {
+    Name:      "complete",
+    ShortName: "c",
+    Usage:     "complete a task on the list",
+    Action: func(c *cli.Context) {
+      println("completed task: ", c.Args().First())
+    },
+  },
+  {
+    Name:      "template",
+    ShortName: "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",
+    ShortName: "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`

+## 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.

+# CMakeParseArguments
+# -------------------
+#
+#
+#
+# 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.

+# 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}"
