# Hash              = everything that follows is a comment.
# Leading slash     = matches the directory containing the .gitignore file.
# No leading slash  = matches anywhere in the repository, from the directory containing the .gitignore file and deeper.
# Trailing slash    = matches a directory itself, but not a file.
# No trailing slash = matches a directory or a file.
# *                 = matches 0 or more characters (except /).
