" File: explorer.vim
" Author: M A Aziz Ahmed (aziz@acorn-networks.com)
" Last Change: Sun Mar 31 11:00 PM 2002 PST
" Version: 2.5
" Additions by Mark Waggoner (waggoner@aracnet.com) et al.
"-----------------------------------------------------------------------------
" This file implements a file explorer. Latest version available at:
" http://www.freespeech.org/aziz/vim/
" Updated version available at:
" http://www.aracnet.com/~waggoner
"-----------------------------------------------------------------------------
" Normally, this file will reside in the plugins directory and be
" automatically sourced. If not, you must manually source this file
" using :source explorer.vim
"
" To use it, just edit a directory (vi dirname) or type :Explore to
" launch the file explorer in the current window, or :Sexplore to split
" the current window and launch explorer there.
"
" If the current buffer is modified, the window is always split.
"
" It is also possible to delete files and rename files within explorer.
" See :help file-explorer for more details
"
"-----------------------------------------------------------------------------
" Update history removed, it's not very interesting.
" Contributors were: Doug Potts, Bram Moolenaar, Thomas Köhler
"
" This is a modified version to be compatible with winmanager.vim.
