Git therefore provides "exclude patterns" for telling git which files to
actively ignore. Exclude patterns are thoroughly explained in the
-"Exclude Patterns" section of the gitlink:git-ls-files[1] manual page,
-but the heart of the concept is simply a list of files which git should
-ignore. Entries in the list may contain globs to specify multiple files,
-or may be prefixed by "`!`" to explicitly include (un-ignore) a previously
-excluded (ignored) file (i.e. later exclude patterns override earlier ones).
-The following example should illustrate such patterns:
