+// This is a basic Mill build for a single `ScalaNativeModule`, with one
+// third-party dependencies and a test suite using the uTest framework. As a
+// single-module project, it `extends RootModule` to mark `object foo` as the
+// top-level module in the build. This lets us directly perform operations

+// `foo.compile` or `foo.run`.

+//
+// You can download this example project using the *download* link above
+// if you want to try out the commands below yourself. The only requirement is
+// that you have some version of the JVM installed; the `./mill` script takes
+// care of any further dependencies that need to be downloaded.
+//
+// The source code for this module lives in the `src/` folder.
+// Output for this module (compiled files, resolved dependency lists, ...)
+// lives in `out/`.
+//
+//// SNIPPET:DEPENDENCIES
+//
+// This example project uses a third-party dependency - Fansi to color text in terminal.
+//
+// You can run `assembly` to generate a standalone executable jar, which then
+// can be run from the command line or deployed to be run elsewhere.

+// The output of every Mill task is stored in the `out/` folder under a name
+// corresponding to the task that created it. e.g. The `assembly` task puts its
+// metadata output in `out/assembly.json`, and its output files in
+// `out/assembly.dest`. You can also use `show` to make Mill print out the
+// metadata output for a particular task.
+//
+// Additional Mill tasks you would likely need include:
+//
+// [source,bash]
+// ----
+// $ mill runBackground # run the main method in the background
+//
+// $ mill clean <task>  # delete the cached output of a task, terminate any runBackground
+//
+// $ mill launcher      # prepares a foo/launcher.dest/run you can run later
+//
+// $ mill jar           # bundle the classfiles into a jar suitable for publishing
+//
+// $ mill -i console    # start a Scala console within your project
+//
+// $ mill -i repl       # start an Ammonite Scala REPL within your project
+// ----
+//
+// You can run `+mill resolve __+` to see a full list of the different tasks that
+// are available, `+mill resolve _+` to see the tasks within `foo`,
+// `mill inspect compile` to inspect a task's doc-comment documentation or what
+// it depends on, or `mill show foo.scalaVersion` to show the output of any task.
+//
+// The most common *tasks* that Mill can run are cached *targets*, such as
+// `compile`, and un-cached *commands* such as `foo.run`. Targets do not
+// re-evaluate unless one of their inputs changes, whereas commands re-run every
+// time.

+//// SNIPPET:END
+
+// This example contains a simple Mill build with two modules, `foo` and `bar`.
+// We don't mark either module as top-level using `extends RootModule`, so
+// running tasks needs to use the module name as the prefix e.g. `foo.run` or
+// `bar.run`. You can define multiple modules the same way you define a single
+// module, using `def moduleDeps` to define the relationship between them.
+//
+// Note that we split out the `test` submodule configuration common to both
+// modules into a separate `trait MyModule`. This lets us avoid the need to
+// copy-paste common settings, while still letting us define any per-module
+// configuration such as `ivyDeps` specific to a particular module.
+//
+// The above builds expect the following project layout:
+//
+//// SNIPPET:TREE
+//
+// ----
+// build.mill
+// foo/
+//     src/
+//         Foo.scala
+//     resources/
+//         ...
+// bar/
+//     src/
+//         Bar.scala
+//     resources/
+//         ...
+// out/
+//     foo/
+//         compile.json
+//         compile.dest/
+//         ...
+//     bar/
+//         compile.json
+//         compile.dest/
+//         ...
+// ----
+//
+//// SNIPPET:END
+// Typically, both source code and output files in Mill follow the module
+// hierarchy, so e.g. input to the `foo` module lives in `foo/src/` and
+// compiled output files live in `out/foo/compile.dest`.
+
+/** Usage
+
+> mill resolve __.run
+foo.run
+bar.run
+
+> mill foo.run --foo-text hello --bar-text world
+Foo.value: hello
+Bar.value: <h1>world</h1>
+
+> mill bar.run world
+Bar.value: <h1>world</h1>
+
+> mill bar.test
+...
+...bar.BarTests...simple...
+...bar.BarTests...escaping...
+
+*/
+
+// Mill's evaluator will ensure that the modules are compiled in the right
+// order, and recompiled as necessary when source code in each module changes.
+//
+// You can use wildcards and brace-expansion to select
+// multiple targets at once or to shorten the path to deeply nested targets. If
+// you provide optional target arguments and your wildcard or brace-expansion is
+// resolved to multiple targets, the arguments will be applied to each of the
+// targets.
+//
+// .Wildcards and brace-expansion
+// |==========================================================
+// | Wildcard | Function
+// | `_`      | matches a single segment of the target path
+// | `__`     | matches arbitrary segments of the target path
+// | `{a,b}`  | is equal to specifying two targets `a` and `b`
+// |==========================================================
+//
+//
+// You can use the `+` symbol to add another target with optional arguments.
+// If you need to feed a `+` as argument to your target, you can mask it by
+// preceding it with a backslash (`\`).
+//
+// === Examples
+//
+// `+mill foo._.compile+`:: Runs `compile` for all direct sub-modules of `foo`
+// `+mill foo.__.test+` :: Runs `test` for all sub-modules of `foo`
+// `+mill {foo,bar}.__.testCached+` :: Runs `testCached` for all sub-modules of `foo` and `bar`
+// `+mill __.compile + foo.__.test+` :: Runs all `compile` targets and all tests under `foo`.

-// This example contains a simple Mill build with two modules, `foo` and `bar`.
-// We don't mark either module as top-level using `extends RootModule`, so
-// running tasks needs to use the module name as the prefix e.g. `foo.run` or
-// `bar.run`. You can define multiple modules the same way you define a single
-// module, using `def moduleDeps` to define the relationship between them.
-//
-// Note that we split out the `test` submodule configuration common to both
-// modules into a separate `trait MyModule`. This lets us avoid the need to
-// copy-paste common settings, while still letting us define any per-module
-// configuration such as `ivyDeps` specific to a particular module.
-//
-// The above builds expect the following project layout:
-//
-//// SNIPPET:TREE
-//
-// ----
-// build.mill
-// foo/
-//     src/
-//         Foo.scala
-//     resources/
-//         ...
-// bar/
-//     src/
-//         Bar.scala
-//     resources/
-//         ...
-// out/
-//     foo/
-//         compile.json

-// ----

-//// SNIPPET:END
-// Typically, both source code and output files in Mill follow the module
-// hierarchy, so e.g. input to the `foo` module lives in `foo/src/` and
-// compiled output files live in `out/foo/compile.dest`.

-
-// Mill's evaluator will ensure that the modules are compiled in the right
-// order, and recompiled as necessary when source code in each module changes.
-//
-// You can use wildcards and brace-expansion to select
-// multiple targets at once or to shorten the path to deeply nested targets. If
-// you provide optional target arguments and your wildcard or brace-expansion is
-// resolved to multiple targets, the arguments will be applied to each of the
-// targets.
-//
-// .Wildcards and brace-expansion
-// |==========================================================
-// | Wildcard | Function
-// | `_`      | matches a single segment of the target path
-// | `__`     | matches arbitrary segments of the target path
-// | `{a,b}`  | is equal to specifying two targets `a` and `b`
-// |==========================================================
-//
-//
-// You can use the `+` symbol to add another target with optional arguments.
-// If you need to feed a `+` as argument to your target, you can mask it by
-// preceding it with a backslash (`\`).
-//
-// === Examples
-//
-// `+mill foo._.compile+`:: Runs `compile` for all direct sub-modules of `foo`
-// `+mill foo.__.test+` :: Runs `test` for all sub-modules of `foo`
-// `+mill {foo,bar}.__.testCached+` :: Runs `testCached` for all sub-modules of `foo` and `bar`
-// `+mill __.compile + foo.__.test+` :: Runs all `compile` targets and all tests under `foo`.

+// This example contains a simple Mill build with two modules, `foo` and `bar`.
+// We don't mark either module as top-level using `extends RootModule`, so
+// running tasks needs to use the module name as the prefix e.g. `foo.run` or
+// `bar.run`. You can define multiple modules the same way you define a single
+// module, using `def moduleDeps` to define the relationship between them.
+//
+// Note that we split out the `test` submodule configuration common to both
+// modules into a separate `trait MyModule`. This lets us avoid the need to
+// copy-paste common settings, while still letting us define any per-module
+// configuration such as `ivyDeps` specific to a particular module.
+//
+// The above builds expect the following project layout:

+This page contains examples of using Mill as a build tool for scala-native applications.
+It covers setting up a basic basic scala-native application that calls C function within it,
+as well as example of two modules with a scala-naive application.

+// Note the use of `millSourcePath`, `Task.dest`, and `PathRef` when preforming

+//
+// 1. `millSourcePath` refers to the base path of the module. For the root
+//    module, this is the root of the repo, and for inner modules it would be
+//    the module path e.g. for module `foo.bar.qux` the `millSourcePath` would
+//    be `foo/bar/qux`. This can also be overriden if necessary
+//
+// 2. `Task.dest` refers to the destination folder for a task in the `out/`
+//    folder. This is unique to each task, and can act as both a scratch space
+//    for temporary computations as well as a place to put "output" files,
+//    without worrying about filesystem conflicts with other tasks
+//
+// 3. `PathRef` is a way to return the *contents* of a file or folder, rather
+//    than just its path as a string. This ensures that downstream tasks
+//    properly invalidate when the contents changes even when the path stays
+//    the same

-// Note the use of `millSourcePath`, `Task.dest`, and `PathRef` when preforming

-// 1. `millSourcePath` refers to the base path of the module. For the root

-//    the module path e.g. for module `foo.bar.qux` the `millSourcePath` would
-//    be `foo/bar/qux`. This can also be overriden if necessary
-//
-// 2. `Task.dest` refers to the destination folder for a task in the `out/`
-//    folder. This is unique to each task, and can act as both a scratch space
-//    for temporary computations as well as a place to put "output" files,
-//    without worrying about filesystem conflicts with other tasks
-//
-// 3. `PathRef` is a way to return the *contents* of a file or folder, rather
-//    than just its path as a string. This ensures that downstream tasks
-//    properly invalidate when the contents changes even when the path stays
-//    the same
