''' Allows Leo to read a complete directory tree into a Leo outline. Converts
directories into headlines and puts the list of file names into bodies.

Ce plug-in permet de traduire l'arborescence d'un répertoire en une arborescence
Leo : Chaque dossier est converti en noeud dans Leo ; son nom est placé dans
l'entête du noeud et chaque nom de fichier qu'il contient est listé dans son
contenu.

Feedback on this plugin can be sent to::

# 1.3 Original version by Frédéric Momméja
# 
# 1.4 EKR:  Changes for 4.3 code base and new plugins style.
# 
#     - Created typical init and onCreate functions.
#     - Created language global.
#     - Changed true/false to True/False.
#     - Used g.os_path functions to support Unicode properly.
#     - Added '@first # -*- coding: utf-8 -*-' to suppress deprecation warning.
# 1.5 EKR:
#     - use g.importExtension to import tkFileDialog.
#     - Redraw the screen only once (in readDir instead of importDir).
# 1.6 EKR:
#     - Changed 'new_c' logic to 'c' logic.
#     - Added init function.
# 2.0 EKR: now gui independent.
