Spitfire Patcher

This is a custom patcher for applying modifications to firefox source code. It processes patch files located in the `./patches` directory and applies them to files in a specified root path.

How to Use

1. Place your patch files in the ./patches directory. Example of patch file:

   --- /browser/branding/official/configure.sh
   +++ /browser/branding/official/configure.sh
   
   -MOZ_APP_DISPLAYNAME=Firefox
   +MOZ_APP_DISPLAYNAME=Spitfire
   

2. Run the patcher with the --path flag:

   go run patch.go --path=./mozilla-central
   

Root path will be resolved to an absolute path, and patches will be applied relative to this path.
