Due to limitation of the google repo tool you need to manually apply a repo patch to the repo repository when porting android to other platforms. This script automates this process.
Use this script to automatically split the repo patch file in individual patch files and automatically apply them to the individual git repositories inside the repo repository. Usage: repo-apply The script will take the patch file and split the file into individual patch files for each git repository. Then the script will apply each individual patch file to the correct git repository using 'git apply'.
