+   by such Contributor that are necessarily infringed by their
+   Contribution(s) alone or by combination of their Contribution(s)
+   with the Work to which such Contribution(s) was submitted. If You
+   institute patent litigation against any entity (including a
+   cross-claim or counterclaim in a lawsuit) alleging that the Work
+   or a Contribution incorporated within the Work constitutes direct
+   or contributory patent infringement, then any patent licenses
+   granted to You under this License for that Work shall terminate
+   as of the date such litigation is filed.
+
+4. Redistribution. You may reproduce and distribute copies of the
+   Work or Derivative Works thereof in any medium, with or without
+   modifications, and in Source or Object form, provided that You
+   meet the following conditions:
+
+   (a) You must give any other recipients of the Work or
+       Derivative Works a copy of this License; and
+
+   (b) You must cause any modified files to carry prominent notices
+       stating that You changed the files; and
+
+   (c) You must retain, in the Source form of any Derivative Works
+       that You distribute, all copyright, patent, trademark, and
+       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
+       include a readable copy of the attribution notices contained
+       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
+       documentation, if provided along with the Derivative Works; or,
+       within a display generated by the Derivative Works, if and
+       wherever such third-party notices normally appear. The contents
+       of the NOTICE file are for informational purposes only and
+       do not modify the License. You may add Your own attribution
+       notices within Derivative Works that You distribute, alongside
+       or as an addendum to the NOTICE text from the Work, provided
+       that such additional attribution notices cannot be construed
+       as modifying the License.
+
+   You may add Your own copyright statement to Your modifications and
+   may provide additional or different license terms and conditions
+   for use, reproduction, or distribution of Your modifications, or
+   for any such Derivative Works as a whole, provided Your use,
+   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
+   implied, including, without limitation, any warranties or conditions
+   of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+   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.

+
+This crate provides a procedural macro for indented string literals. The
+`indoc!()` macro takes a multiline string literal and un-indents it at compile
+time so the leftmost non-space character is in the first column.
+
+```toml
+[dependencies]
+indoc = "1.0"
+```
+
+*Compiler requirement: rustc 1.45 or greater.*
+
+<br>
+
+## Using indoc
+
+```rust
+use indoc::indoc;
+
+fn main() {
+    let testing = indoc! {"
+        def hello():
+            print('Hello, world!')
+
+        hello()
+    "};
+    let expected = "def hello():\n    print('Hello, world!')\n\nhello()\n";
+    assert_eq!(testing, expected);
+}
+```
+
+Indoc also works with raw string literals:
+
+```rust
+use indoc::indoc;
+
+fn main() {
+    let testing = indoc! {r#"
+        def hello():
+            print("Hello, world!")
+
+        hello()
+    "#};
+    let expected = "def hello():\n    print(\"Hello, world!\")\n\nhello()\n";
+    assert_eq!(testing, expected);
+}
+```
+
+And byte string literals:
+
+```rust
+use indoc::indoc;
+
+fn main() {
+    let testing = indoc! {b"
+        def hello():
+            print('Hello, world!')
+
+        hello()
+    "};
+    let expected = b"def hello():\n    print('Hello, world!')\n\nhello()\n";
+    assert_eq!(testing[..], expected[..]);
+}
+```
+
+<br>
+
+## Formatting macros
+
+The indoc crate exports four additional macros to substitute conveniently for
+the standard library's formatting macros:
+
+- `formatdoc!($fmt, ...)`&ensp;&mdash;&ensp;equivalent to `format!(indoc!($fmt), ...)`
+- `printdoc!($fmt, ...)`&ensp;&mdash;&ensp;equivalent to `print!(indoc!($fmt), ...)`

+- `writedoc!($dest, $fmt, ...)`&ensp;&mdash;&ensp;equivalent to `write!($dest, indoc!($fmt), ...)`
+
+```rust
+use indoc::printdoc;
+
+fn main() {
+    printdoc! {"
+        GET {url}
+        Accept: {mime}
+        ",
+        url = "http://localhost:8080",
+        mime = "application/json",
+    }
+}
+```
+
+<br>
+
+## Explanation
+
+The following rules characterize the behavior of the `indoc!()` macro:
+
+1. Count the leading spaces of each line, ignoring the first line and any lines
+   that are empty or contain spaces only.
+2. Take the minimum.
+3. If the first line is empty i.e. the string begins with a newline, remove the
+   first line.
+4. Remove the computed number of spaces from the beginning of each line.
+
+<br>
+
+## Unindent
+
+Indoc's indentation logic is available in the `unindent` crate. This may be
+useful for processing strings that are not statically known at compile time.
+
+The crate exposes two functions:
+
+- `unindent(&str) -> String`
+- `unindent_bytes(&[u8]) -> Vec<u8>`
+
+```rust
+use unindent::unindent;
+
+fn main() {
+    let indented = "
+            line one
+            line two";
+    assert_eq!("line one\nline two", unindent(indented));
+}
+```

+//!
+//! <br>
+//!
+//! This crate provides a procedural macro for indented string literals. The
+//! `indoc!()` macro takes a multiline string literal and un-indents it at
+//! compile time so the leftmost non-space character is in the first column.
+//!
+//! ```toml
+//! [dependencies]
+//! indoc = "1.0"
+//! ```
+//!
+//! <br>
+//!
+//! # Using indoc
+//!
+//! ```
+//! use indoc::indoc;
+//!
+//! fn main() {
+//!     let testing = indoc! {"
+//!         def hello():
+//!             print('Hello, world!')
+//!
+//!         hello()
+//!     "};
+//!     let expected = "def hello():\n    print('Hello, world!')\n\nhello()\n";
+//!     assert_eq!(testing, expected);
+//! }
+//! ```
+//!
+//! Indoc also works with raw string literals:
+//!
+//! ```
+//! use indoc::indoc;
+//!
+//! fn main() {
+//!     let testing = indoc! {r#"
+//!         def hello():
+//!             print("Hello, world!")
+//!
+//!         hello()
+//!     "#};
+//!     let expected = "def hello():\n    print(\"Hello, world!\")\n\nhello()\n";
+//!     assert_eq!(testing, expected);
+//! }
+//! ```
+//!
+//! And byte string literals:
+//!
+//! ```
+//! use indoc::indoc;
+//!
+//! fn main() {
+//!     let testing = indoc! {b"
+//!         def hello():
+//!             print('Hello, world!')
+//!
+//!         hello()
+//!     "};
+//!     let expected = b"def hello():\n    print('Hello, world!')\n\nhello()\n";
+//!     assert_eq!(testing[..], expected[..]);
+//! }
+//! ```
+//!
+//! <br><br>
+//!
+//! # Formatting macros
+//!
+//! The indoc crate exports four additional macros to substitute conveniently
+//! for the standard library's formatting macros:
+//!
+//! - `formatdoc!($fmt, ...)`&ensp;&mdash;&ensp;equivalent to `format!(indoc!($fmt), ...)`
+//! - `printdoc!($fmt, ...)`&ensp;&mdash;&ensp;equivalent to `print!(indoc!($fmt), ...)`
+//! - `eprintdoc!($fmt, ...)`&ensp;&mdash;&ensp;equivalent to `eprint!(indoc!($fmt), ...)`
+//! - `writedoc!($dest, $fmt, ...)`&ensp;&mdash;&ensp;equivalent to `write!($dest, indoc!($fmt), ...)`
+//!
+//! ```
+//! use indoc::printdoc;
+//!
+//! fn main() {
+//!     printdoc! {"
+//!         GET {url}
+//!         Accept: {mime}
+//!         ",
+//!         url = "http://localhost:8080",
+//!         mime = "application/json",
+//!     }
+//! }
+//! ```
+//!
+//! <br><br>
+//!
+//! # Explanation
+//!
+//! The following rules characterize the behavior of the `indoc!()` macro:
+//!
+//! 1. Count the leading spaces of each line, ignoring the first line and any
+//!    lines that are empty or contain spaces only.
+//! 2. Take the minimum.
