+.. versionadded:: 2.2
+
+The ``-x`` flag enables custom lexers and formatters to be loaded
+from files relative to the current directory. Create a file with a class named
+CustomLexer or CustomFormatter, then specify it on the command line::
+
+    $ pygmentize -l your_lexer.py -f your_formatter.py -x
+
+You can also specify the name of your class with a colon::
+
+    $ pygmentize -l your_lexer.py:SomeLexer -x
