+# TAB-Completion for Jython with org.python.util.ReadlineConsole.
+# JReadlineCompleter.py,v 1.1 2007/09/28 08:18:43 martin Exp
+#
+# This is rlcompleter.py from CPython 2.5.1 adapted for Jython
+# and libreadline-java.
+
+"""TAB-completion for Jython + libreadline-java
+
+The completer completes keywords, built-ins and globals in a
+selectable namespace (which defaults to __main__); when completing
+NAME.NAME..., it evaluates (!) the expression up to the last dot and
+completes its attributes.
+
+It's very cool to do "import sys" type "sys.", hit the
+completion key (twice), and see the list of names defined by the
+sys module!
+
+Notes:
+
+- Exceptions raised by the completer function are *ignored* (and
+generally cause the completion to fail).  This is a feature -- since
+readline sets the tty device in raw (or cbreak) mode, printing a
+traceback wouldn't work well without some complicated hoopla to save,
+reset and restore the tty state.
+
+- The evaluation of the NAME.NAME... form may cause arbitrary
+application defined code to be executed if an object with a
+__getattr__ hook is found.  Since it is the responsibility of the
+application (or the user) to enable this feature, I consider this an
+acceptable risk.  More complicated expressions (e.g. function calls or
+indexing operations) are *not* evaluated.
+
+This module is a hacked version of the CPython 2.5 module rlcompleter.
+It is under the PSF (Python Software Foundation) license.

+Java-Readline is a port of GNU Readline for Java. Or, to be more
+precise, it is a JNI-wrapper to Readline. It is distributed under the
+LGPL.
+
+You must call Readline.load(ReadlineLibrary lib); before using any
+other methods.  If you omit the call to the load()-method, the pure
+Java fallback solution is used.  Possible values for lib are:
+
+ReadlineLibrary.PureJava
+ReadlineLibrary.GnuReadline
+ReadlineLibrary.Editline
+ReadlineLibrary.Getline
+
+Note that all programs using GnuReadline will fall under the GPL,
+since Gnu-Readline is GPL software!
