How do I make changes to a package and capture them using ltib

1. Unpack the sources and apply all current patches:

./ltib -m prep -p u-boot

2. Edit/add files under rpm/BUILD/package/
3. Build the package with your changes:

./ltib -m scbuild -p u-boot

4. Once the package builds successfully, check the install phase:

./ltib -m scinstall -p u-boot

5. Test your package before committing the changes:

./ltib -m scdeploy -p u-boot

6. Repeat steps 2 -> 5 until you are satisfied with your results.
