+Manipulate a cell phone's filesystem calling obexftp binary. This is a complete
+user-mode solution, no kernel modules required (unlike SieFS or such). The
+script implements all commands of Midnight VFS, except for undocumented "run";
+but there are no runnable files in the cell phone. The script is written in
+Python because I love Python, the best of all languages, and I need to parse
+XML directory listings from obexftp.
+

 The script requires Midnight Commander 3.1+ (http://www.ibiblio.org/mc/),
 The script requires Midnight Commander 3.1+ (http://www.ibiblio.org/mc/),

-Edit the full path to the obexftp binary (see below). Put the file to the
-/usr/[local/]lib/mc/extfs, and add a line "obexftp" to the
-/usr/[local/]lib/mc/extfs/extfs.ini. Then create somewhere a file called
-"irda", "bluetooth" or "tty" to connect to the device using IrDA, Bluetooth or
-TTY transport.
+Edit the script, and correct the shebang path, if your python is not in the
+/usr/local. Edit the full path to the obexftp binary (see below). Put the file
+in the /usr/[local/]lib/mc/extfs, and add a line "obexftp" to the
+/usr/[local/]lib/mc/extfs/extfs.ini.
+
+Create somewhere a transport file. The transport file can have any name, and is
+expected to be a text file with at least one line defining the transport to
+your device. Other lines in the file are ignored.

 
 

-For the "bluetooth" put there a line "CP:AD:RE:SS channel", where CP:AD:RE:SS
-is the hardware address of the device you want to connect to, and channel is
-the OBEX File Transfer channel; you can discover the address and the channel
-for your device by using commands like "hcitool scan" and "sdptool browse".
-Other lines in the file are ignored.
+First word in the line is a transport name - Bluetooth, IrDA or TTY. The name
+is case-insensitive.

 
 

-Put a device name like /dev/rfcomm0 into the "tty" file.
+For the Bluetooth transport put there a line "Bluetooth CP:AD:RE:SS channel",
+where CP:AD:RE:SS is the hardware address of the device you want to connect to,
+and channel is the OBEX File Transfer channel; you can discover the address and
+the channel for your device by using commands like "hcitool scan" and "sdptool
+browse".

 
 

-The content for the "irda" file is ignored.
+For the TTY put a device name: "tty /dev/rfcomm0".
+
+For the IrDA: just put "IrDA" in the file.

 
 Now run this "cd" command in the Midnight Commander (in the "bindings" files
 
 Now run this "cd" command in the Midnight Commander (in the "bindings" files

-the command is "%cd"): cd bluetooth#obexftp. The VFS script use obexftp to try
-to connect to the device and list files and directories. Plese be warned that
-opening the VFS for the first time is VERY slow, because the script needs to
-scan the entire cell phone's filesystem. Often obexftp fails to list a
-directory, and the script retries after a second or two timeouts, which don't
-make the scanning process faster. Midnight Commander caches the result.
