+            Support for wildcard use varies depending on the context in
+            which it is used.
+            For example, some variables and file names allow limited use of
+            wildcards through the "<filename>%</filename>" and
+            "<filename>*</filename>" characters.
+            Other variables or names support Python's
+            <ulink url='https://docs.python.org/2/library/glob.html'><filename>glob</filename></ulink>
+            syntax,
+            <ulink url='https://docs.python.org/2/library/fnmatch.html#module-fnmatch'><filename>fnmatch</filename></ulink>
+            syntax, or Regular Expression (re) syntax.

+            When a particular variable's list of filenames or filenames
+            in general used by BitBake or a build system
+            based on BitBake support the use of wildcards, the
+            documentation describes its use and limitations.
