-# Tour
-
-A simple UI tour showcasing different widgets that can be built using Iced. It
-also shows how the library can be integrated into an existing system.
-
-The example can run both on native and web platforms, using the same GUI code!
-
-The native renderer of the example is built on top of [`ggez`], a game library
-for Rust. Currently, it is using a [personal fork] to [add a `FontCache` type]
-and [fix some issues with HiDPI].
-
-The web version uses `iced_web` directly. This crate is still a work in
-progress. In particular, the styling of elements is not finished yet
-(text color, alignment, sizing, etc).
-
-The implementation consists of different modules:
-  - __[`tour`]__ contains the actual cross-platform GUI code: __state__,
-    __messages__, __update logic__ and __view logic__.
-  - __[`iced_ggez`]__ implements a simple renderer for each of the used widgets
-    on top of the graphics module of [`ggez`].
-  - __[`widget`]__ conditionally re-exposes the correct platform widgets based
-    on the target architecture.
-  - __[`main`]__ integrates Iced with [`ggez`] and connects the [`tour`] with
-    the native [`renderer`].
-  - __[`lib`]__ exposes the [`tour`] types and conditionally implements the
-    WebAssembly entrypoint in the [`web`] module.
-
-The conditional compilation awkwardness from targetting both native and web
-platforms should be handled seamlessly by the `iced` crate in the near future!
-
-If you want to run it as a native app:
-
-```
-cd examples/tour
-cargo run
-```
-
-If you want to run it on web, you will need [`wasm-pack`]:
-
-```
-cd examples/tour
-wasm-pack build --target web
-```
-
-Then, simply serve the directory with any HTTP server. For instance:
-
-```
-python3 -m http.server
-```

-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.

-          attribution notices from the Source form of the Work,
-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must

-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or

-          notices within Derivative Works that You distribute, alongside

-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and

-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
-
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or

-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.
