-### Examples
-
-1. Write commit contents in the patch format to stdout.
-```
-$ ./script/get-patch --repo src --commit 8e8216e5
-```
-
-2. Create a patch file with a default name if a specified directory.
-```
-$ ./script/get-patch --repo src --commit 8e8216e5 --output-dir patches
-```
-
-3. Create a patch file with a custom name in the current directory.
-```
-$ ./script/get-patch --repo src --commit 8e8216e5 --filename my.patch
-```
-
-4. Create a patch file with a custom name in a specified directory.
-```
-$ ./script/get-patch --repo src --commit 8e8216e5 --output-dir patches --filename my.patch
-```
-
-5. Create patch files with default names in a specified directory.
-```
-$ ./script/get-patch --repo src --output-dir patches --commit 8e8216e5 164c37e3
-```
-
-6. Create patch files with custom names in a specified directory.
-Note that number of filenames must match the number of commits.
-```
-$ ./script/get-patch --repo src --output-dir patches --commit 8e8216e5 164c37e3 --filename first.patch second.patch
