"""Torrent Virtual FileSystem for Midnight Commander
The script requires Midnight Commander 3.1+
(http://www.midnight-commander.org/), Python 2.4+ (http://www.python.org/),
module eff_bdecode.py (http://effbot.org/zone/bencode.htm).
-Put the script in the /usr/[local/][lib|share]/mc/extfs/, and add a line
-"torrent" to the /usr/[local/][lib|share]/mc/extfs/extfs.ini. Make the script
-executable.
+For mc 4.7+ put the script in $HOME/.mc/extfs.d.
+For older versions put it in /usr/[local/][lib|share]/mc/extfs
+and add a line "torrent" to the /usr/[local/][lib|share]/mc/extfs/extfs.ini.
+Make the script executable.
Run this "cd" command in the Midnight Commander (in the "bindings" file the
command is "%cd"): cd file#torrent, where "file" is the name of your torrent
metafile. The VFS lists all files and directories from the torrent metafile;
-all files appear empty, of course, but the sizes are shown.
+all files appear empty, of course, but the sizes are shown. Filenames are
+reencoded from the metafile's encoding to the current locale.
Along with the files/directories in the torrent metafile the VFS also presents
meta information - in the form of files in .META directory. The size and
contents of these files are taken from the corresponding fields in the torrent
-metafile. The VFS doesn't check if the torrent contains .META file or directory
-(quite unlikely).

-Date/time for all files is set at midnight of the 1st January of the current
-year.
+Date/time for all files is set to midnight of the 1st January of the current
