* apply to file paths only. For example, '/a/b' matches all file paths ending with '/a/b';
* and `.svn/` matches directory paths ending with `.svn`.

* For example, `views/*.php` matches `views/index.php` but not `views/controller/index.php`.
* A leading slash matches the beginning of the pathname. For example, `/*.php` matches `index.php` but not `views/start/index.php`.
* An optional prefix `!` which negates the pattern; any matching file excluded by a previous pattern will become included again.
* If a negated pattern matches, this will override lower precedence patterns sources. Put a backslash (`\`) in front of the first `!`
* for patterns that begin with a literal `!`, for example, `\!important!.txt`.
* Note, the '/' characters in a pattern matches both '/' and '\' in the paths.
* - `only`: array, list of patterns that the file paths should match if they are to be returned. Directory paths
