====== Merge Production Branch With Master Branch ======
After making changes to master branch, we want to merge those changes with production branch. However, some files must not 
be merged with those from master branch, e.g., wsgi, env files, settings.py. The solution is selective merge.

Merge with master branch without commits:
     git merge --no-ff --no-commit master
     git status

To select the version in the current branch, run:
     git checkout HEAD wsgi.py

If you want the version in master (and not a true merge), run:
     git checkout master file_name
