attribute. The rules how the pattern matches paths are the
same as in `.gitignore` files; see linkgit:gitignore[5].
+Note that if a .gitignore rule matches a directory, the directory
+is ignored, which may be seen as "ignore" attribute propagated to
+to all files and directories inside. If a .gitattributes rule
+matches a directory, it manipulates attributes on that directory
+only, not files and directories inside.

When deciding what attributes are assigned to a path, git
consults `$GIT_DIR/info/attributes` file (which has the highest
precedence), `.gitattributes` file in the same directory as the

For example, "/{asterisk}.c" matches "cat-file.c" but not
"mozilla-sha1/sha1.c".
+Two consecutive asterisks ("`**`") in patterns matched against
+full pathname may have special meaning:
+
+ - A leading "`**`" followed by a slash means match in all
+ directories. For example, "`**/foo`" matches file or directory
+ "`foo`" anywhere, the same as pattern "`foo`". "**/foo/bar"
+ matches file or directory "`bar`" anywhere that is directly
+ under directory "`foo`".
+
+ - A trailing "/**" matches everything inside. For example,
+ "abc/**" matches all files inside directory "abc", relative
+ to the location of the `.gitignore` file, with infinite depth.
+
+ - A slash followed by two consecutive asterisks then a slash
+ matches zero or more directories. For example, "`a/**/b`"
+ matches "`a/b`", "`a/x/b`", "`a/x/y/b`" and so on.
+
+ - Other consecutive asterisks are considered invalid.
