パターンは、実行時に置き換えられる次の特殊コンポーネントを含む文字列で構成されます。
"/" the local pathname separator
"%t" the system temporary directory
"%h" the value of the "user.home" system property
"%g" the generation number to distinguish rotated logs
"%u" a unique number to resolve conflicts
"%%" translates to a single percent sign "%"
