"""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).
-Make the script executable and put it in the
-/usr/[local/][lib|share]/mc/extfs/, add a line "torrent" to the
-/usr/[local/][lib|share]/mc/extfs/extfs.ini.
+For mc 4.7+ just put the script in $HOME/[.local/share/].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.
+
+For mc 4.7+ run this "cd" command in the Midnight Commander (in the "bindings"
+file the command is "%cd"): cd file/torrent://; In older versions it is
+cd file#torrent, where "file" is the name of your torrent metafile.
+
+See detailed installation instructions at
+https://phdru.name/Software/mc/torrent_INSTALL.html.
-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. Filenames are
-reencoded from the metafile's encoding to the current locale.
+The VFS lists all files and directories from the torrent metafile; all files
+appear empty, of course, but the sizes are shown. Filenames are reencoded from
+the metafile's encoding/codepage 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 consists of .META file or
+metafile. The script doesn't check if the torrent consists of a .META file or
directory (quite unlikely).
-Date/time for all files is set to midnight of the 1st January of the current
-year. The filesystem is, naturally, read-only.
+Date/time for all directories/files is set to the value of 'creation date'
+field, if it exists; if not date/time is set to the last modification time of
+the torrent file itself.
+
+The filesystem is, naturally, read-only.
