"""Torrent Virtual FileSystem for Midnight Commander
The script requires Midnight Commander 3.1+
cd file#torrent, where "file" is the name of your torrent metafile.
See detailed installation instructions at
-http://phdru.name/Software/mc/torrent_INSTALL.html.
+https://phdru.name/Software/mc/torrent_INSTALL.html.
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
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.
