+            Writing scripts for Midnight Commander's external vfs
+
+IMPORTANT NOTE: There may be some bugs left in extfs. Enjoy.
+
+Starting with version 3.1, the Midnight Commander comes with so called
+extfs, which is one of the virtual filesystems. This system makes it
+possible to create new virtual filesystems for the GNU MC very easily.
+
+To handle requests, create a shell/perl/python/etc script/program
+(with executable permissions) in $(libexecdir)/mc/extfs.d
+or in ~/.local/share/mc/extfs.d/.
+
+(Note: $(libexecdir) should be substituted for actual libexecdir path
+stored when configured or compiled, like /usr/local/libexec or /usr/libexec).
+
+Assign a vfs suffix. For example, if you have .zip file, and would like
+to see what's inside it, path will be
+
+/anypath/my.zip/uzip://some_path/...
+
+In this example, .zip is suffix, but I call vfs 'uzip'. Why? Well,
+what this vfs essentially does is UNzip. UN is too long, so I chose
+U. Note that sometime in future filesystem like zip may exist: It will
+take whole tree and create .zip file from it. So /usr/zip:// will be
+zipfile containing whole /usr tree.
+
+If your vfs does not require file to work on, add '+' to the end of name.
+Note, that trailing '+' in file name is not a part of vfs name, it is
+just an vfs attribute. So you have not use it in vfs commands:
+
+cd rpms://
+
+is correct command, and
+
+cd rpms+://
+
+is incorrect command.
+
+
+* Commands that should be implemented by your shell script
+----------------------------------------------------------
+
+Return zero from your script upon completion of the command, otherwise
+nonzero for failure or in case of an unsupported command.
+
+$libdir/extfs/prefix command [arguments]
+
+* Command: list archivename
+
+This command should list the complete archive content in the following format
+(a little modified ls -l listing):
+
+AAAAAAA NNN OOOOOOOO GGGGGGGG SSSSSSSS DATETIME [PATH/]FILENAME [-> [PATH/]FILENAME[/]]]
+
+where (things in [] are optional):
+
+AAAAAAA  is the permission string like in ls -l
+NNN      is the number of links
+OOOOOOOO is the owner (either UID or name)
+GGGGGGGG is the group (either GID or name)
+SSSSSSSS is the file size
+FILENAME is the filename
+PATH     is the path from the archive's root without the leading slash (/)
+DATETIME has one of the following formats:
+            Mon DD hh:mm[:ss], Mon DD YYYY, MM-DD-YYYY hh:mm[:ss]
+
+            where Mon is a three letter English month name, DD is day
+            01-31 (can be 1-31, if following Mon), MM is month 01-12,
+            YYYY is four digit year, hh is hours, mm is minutes,
+            and ss is optional seconds.
+
+If the -> [PATH/]FILENAME part is present, it means:
+
+If permissions start with an l (ell), then it is the name that symlink
+points to. (If this PATH starts with a MC vfs prefix, then it is a symlink
+somewhere to the other virtual filesystem (if you want to specify path from
+the local root, use local:/path_name instead of /path_name, since /path_name
+means from root of the archive listed).
+
+If permissions do not start with l, but number of links is greater than one,
+then it says that this file should be a hardlinked with the other file.
+
+The result of list command must not contain "." and ".." items.
+
+* Command: copyout archivename storedfilename extractto
+
+This should extract from archive archivename the file called
+storedfilename (possibly with path if not located in archive's root
+[this is wrong. current extfs strips paths! -- pavel@ucw.cz])
+to file extractto.
+
+* Command: copyin archivename storedfilename sourcefile
+
+This should add to the archivename the sourcefile with the name
+storedfilename inside the archive.  
+
+Important note: archivename in the above examples may not have the
+extension you are expecting to have, like it may happen that
+archivename will be something like /tmp/f43513254 or just
+anything. Some archivers do not like it, so you'll have to find some
+workaround.
+
+* Command: rm archivename storedfilename
+
+This should remove storedfilename from archivename.
+
+* Command: mkdir archivename dirname
+
+This should create a new directory called dirname inside archivename.
+
+* Command: rmdir archivename dirname
+
+This should remove an existing directory dirname. If the directory is
+not empty, mc will recursively delete it (possibly prompting).
+
+* Command: run
+
+Undocumented :-)
+
+---------------------------------------------------------
+
+Don't forget to mark this file executable (chmod 755 ThisFile, for example)
+
+For skeleton structure of executable, look at some of filesystems
+similar to yours.
+
+---------------------------------------------------------
+
+In constructing these routines, errors will be made, and mc will not display
+a malformed printing line.  That can lead the programmer down many false
+trails in search of the bug.  Since this routine is an executable shell script
+it can be run from the command line independently of mc, and its output will
+show on the console or can be redirected to a file.
+
+* Putting it to use
+----------------------------------------------------------
+The file .mc.ext in a home directory, and in mc's user directory (commonly
+/etc/mc), contains instructions for operations on files depending
+on filename extensions.  It is well documented in other files in this 
+distribution, so here are just a few notes specifically on use of the
+Virtual File System you just built.
+
+There are entries in .mc.ext defining a few operations that can be done on a
+file from an mc panel.  Typically they are annotated with a hash mark and a
+file extension like this:
+
+# zip
+
+There must be a way to find the file by extension, so the next line does
+that.  In essence it says "identify the string ".zip" or (|) ".ZIP" at the
+end ($) of a filename": 
+
+regex/\.(zip|ZIP)$
+
+The operations themselves follow that. They must be indented by at least a
+space, and a tab works as well.  In particular, the Open operation will
+now use your new virtual file system by cd'ing to it like this:
+
+   Open=%cd zip:%d/%p
+
+This is the line used when a file is highlighted in a panel and the user
+presses <Enter> or <Return>.  The contents of the archive should show just
+as if they were in a real directory, and can be manipulated as such.
+The rest of the entry pertains to use of the F3 View key:
+
+   View=%view{ascii} unzip -v %f
+
+And perhaps an optional icon for X:
+
+   Icon=zip.xpm
+
+And perhaps an operation to extract the contents of the file, called from
+a menu selection:
+
+   Extract=unzip %f '*'
+
+This is just an example.  The current entry for .zip files has a menu selection
+of 'Unzip' which could be used in place of 'Extract'.  What goes here depends
+on what items you have in, or add to, the menu system, and that's another 
+subject.  The sum of this is the .mc.ext entry:
+
+# zip
+regex/\.(zip|ZIP)$
+   Open=%cd %p/uzip://
+   View=%view{ascii} unzip -v %f
+   Icon=zip.xpm
+   Extract=unzip %f '*'
+
+Add an entry like this to the .mc.ext file in a user's home directory, If you
+want others to have it, add it to the mc.ext file in the mc system directory,
+often /etc/mc/mc.ext.  Notice this file is not prepended with a dot.
+
+Once all this is done, and things are in their proper places, exit mc if you
+were using it, and restart it so it picks up the new information.
+
+That's all there is to it.  The hardest part is making a listing function
+that sorts the output of a system listing command and turns it into a form
+that mc can use.  Currently awk (or gawk) is used because nearly all systems
+have it. If another scripting language is available, like perl, that could
+also be used.

+# This script makes it possible to view and copy files to/from a hp48
+# (tested with a HP48G and the emulator x48)
+#
+# To use the hp48 external filesystem:
+#      - read the relevant parts of your HP48 manual
+#      - install kermit
+#      - connect the HP48 to your computer or start x48
+#      - below change the line which reflects the serial device you use
+#      - configure your HP48 (<left shift> - i/o - iopar): 
+#        port: wire
+#        baud: 9600 
+#        transfer format: binary (fast transfers) or
+#                         ascii (editable on the pc)
+#      - start the server on the HP48: <left shift> - i/o - srvr - serve
+#        or the shortcut <right shift> - <right arrow>
+#      - on MC's commandline enter "cd hp48://"
+#

+# device by changing /dev/ttyXX on the next line

+#
+#
+# Notes:
+#  This EXTFS exposes buckets as directories and keys as files
+#  Due to EXTFS limitations all buckets & keys have to be read initially which might
+#  take quite some time.
+#  Tested on Debian with Python 2.4-2.6 and boto 1.4c and 1.6b
+#    (Python 2.6 might need -W ignore::DeprecationWarning due to boto using
+#    deprecated module Popen2)
+#
+#
+# Installation:
+#  Make sure that boto <http://code.google.com/p/boto> (python-boto in Debian) is installed.
+#  Preferably pytz (package python-tz in Debian) should be installed as well.
+#
+#  Save as executable file /usr/libexec/mc/extfs/s3 (or wherever your mc expects to find extfs modules)
+#
+# Settings: (should be set via environment)
+#  Required:
+#    AWS_ACCESS_KEY_ID         : Amazon AWS access key (required)
+#    AWS_SECRET_ACCESS_KEY     : Amazon AWS secret access key (required)
+#  Optional:
+#    MCVFS_EXTFS_S3_LOCATION   : where to create new buckets: "EU" - default, "USWest", "APNortheast" etc.
+#    MCVFS_EXTFS_S3_DEBUGFILE  : write debug info to this file (no info by default)
+#    MCVFS_EXTFS_S3_DEBUGLEVEL : debug messages level ("WARNING" - default, "DEBUG" - verbose)
+#
+#
+# Usage:
+#  Open dialog "Quick cd" (<alt-c>) and type: s3:// <enter> (or simply type `cd s3://' in shell line)
+#
+#
+# History:
+#
+#  2015-07-22 Dmitry Koterov <dmitry.koterov@gmail.com>
+#   - Support for non-ASCII characters in filenames (system encoding detection).
+#
+#  2015-05-21 Dmitry Koterov <dmitry.koterov@gmail.com>
+#   - Resolve "Please use AWS4-HMAC-SHA256" error: enforce the new V4 authentication method.
+#     It is required in many (if not all) locations nowadays.
+#   - Now s3+ works with buckets in different regions: locations are auto-detected.
+#   - Debug level specification support (MCVFS_EXTFS_S3_DEBUGLEVEL).
+#
+#  2009-02-07 Jakob Kemi <jakob.kemi@gmail.com>
+#   - Updated instructions.
+#   - Improved error reporting.
+#
+#  2009-02-06 Jakob Kemi <jakob.kemi@gmail.com>
+#   - Threaded list command.
+#   - Handle rm of empty "subdirectories" (as seen in mc).
+#   - List most recent datetime and total size of keys as directory properties.
+#   - List modification time in local time.
+#
+#  2009-02-05 Jakob Kemi <jakob.kemi@gmail.com>
+#   - Initial version.

+# Code for mc_lha_fs_run() suggested by:
+# Jan 97	Zdenek Kabelac <kabi@informatics.muni.cz>
+
+# Tested with mc 3.5.18 and gawk 3.0.0 on Linux 2.0.0
+# Tested with lha v1.01 and lharc v1.02
+# Information and sources for other forms of lha/lzh appreciated
+
+# Nota bene:
+# There are several compression utilities which produce *.lha files.
+# LHArc and LHa in exist several versions, and their listing output varies.
+# Another variable is the architecture on which the compressed file was made.
+# This program attempts to sort out the variables known to me, but it is likely
+# to display an empty panel if it encounters a mystery. 
+# In that case it will be useful to execute this file from the command line:
+# ./lha list Mystery.lha
+# to examine the output directly on the console.  The output string must be
+# precisely in the format described in the README in this directory.
+# Caveat emptor.
+# Learn Latin.

+		FIles transferred over SHell protocol (V 0.0.3)
+		~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This protocol was designed for transferring files over a remote shell
+connection (rsh and compatibles). It can be as well used for transfers over 
+rsh, and there may be other uses.
+
+Client sends requests of following form:
+
+#FISH_COMMAND
+equivalent shell commands,
+which may be multiline
+
+Only fish commands are defined here, shell equivalents are for your
+information only and will probably vary from implementation to
+implementation. Fish commands always have priority: server is
+expected to execute fish command if it understands it. If it does not,
+however, it can try the luck and execute shell command.
+
+Since version 4.7.3, the scripts that FISH sends to host machines after
+a command is transmitted are no longer hardwired in the Midnight
+Commander source code.
+
+First, mc looks for system-wide set of scripts, then it checks whether
+current user has host-specific overrides in his per-user mc
+configuration directory. User-defined overrides take priority over
+sytem-wide scripts if they exist. The order in which the directories are
+traversed is as follows:
+
+    /usr/libexec/mc/fish
+    ~/.local/share/mc/fish/<hostname>/
+
+Server's reply is multiline, but always ends with
+
+### 000<optional text>
+
+line. ### is prefix to mark this line, 000 is return code. Return
+codes are superset to those used in ftp.
+
+There are few new exit codes defined:
+
+000 don't know; if there were no previous lines, this marks COMPLETE
+success, if they were, it marks failure.
+
+001 don't know; if there were no previous lines, this marks
+PRELIMinary success, if they were, it marks failure
+
+				Connecting
+				~~~~~~~~~~
+Client uses "echo FISH:;/bin/sh" as command executed on remote
+machine. This should make it possible for server to distinguish FISH
+connections from normal rsh/ssh.
+
+				Commands
+				~~~~~~~~
+#FISH
+echo; start_fish_server; echo '### 200'
+
+This command is sent at the beginning. It marks that client wishes to
+talk via FISH protocol. #VER command must follow. If server
+understands FISH protocol, it has option to put FISH server somewhere
+on system path and name it start_fish_server.
+
+#VER 0.0.2 <feature1> <feature2> <...>
+echo '### 000'
+
+This command is the second one. It sends client version and extensions
+to the server. Server should reply with protocol version to be used,
+and list of extensions accepted.
+
+VER 0.0.0 <feature2>
+### 200
+
+#PWD
+pwd; echo '### 200'
+
+Server should reply with current directory (in form /abc/def/ghi)
+followed by line indicating success.
+
+#LIST /directory
+ls -lLa $1 | grep '^[^cbt]' | ( while read p x u g s m d y n; do echo "P$p $u.$g
+S$s
+d$m $d $y
+:$n
+"; done )
+ls -lLa $1 | grep '^[cb]' | ( while read p x u g a i m d y n; do echo "P$p $u.$g
+E$a$i
+dD$m $d $y
+:$n
+"; done )
+echo '### 200'
+
+This allows client to list directory or get status information about
+single file. Output is in following form (any line except :<filename>
+may be omitted):
+
+P<unix permissions> <owner>.<group>
+S<size>
+d<3-letters month name> <day> <year or HH:MM>
+D<year> <month> <day> <hour> <minute> <second>[.1234]
+E<major-of-device>,<minor>
+:<filename>
+L<filename symlink points to>
+<blank line to separate items>
+
+Unix permissions are of form X--------- where X is type of
+file. Currently, '-' means regular file, 'd' means directory, 'c', 'b'
+means character and block device, 'l' means symbolic link, 'p' means
+FIFO and 's' means socket.
+
+'d' has three fields: month (one of strings Jan Feb Mar Apr May Jun
+Jul Aug Sep Oct Nov Dec), day of month, and third is either single
+number indicating year, or HH:MM field (assume current year in such
+case). As you've probably noticed, this is pretty broken; it is for
+compatibility with ls listing.
+
+#RETR /some/name
+ls -l /some/name | ( read a b c d x e; echo $x ); echo '### 100'; cat /some/name; echo '### 200'
+
+Server sends line with filesize on it, followed by line with ### 100
+indicating partial success, then it sends binary data (exactly
+filesize bytes) and follows them with (with no preceding newline) ###
+200.
+
+Note that there's no way to abort running RETR command - except
+closing the connection.
+
+#STOR <size> /file/name
+> /file/name; echo '### 001'; ( dd bs=4096 count=<size/4096>; dd bs=<size%4096> count=1 ) 2>/dev/null | ( cat > %s; cat > /dev/null ); echo '### 200'
+
+This command is for storing /file/name, which is exactly size bytes
+big. You probably think I went crazy. Well, I did not: that strange
+cat > /dev/null has purpose to discard any extra data which was not
+written to disk (due to for example out of space condition).
+
+[Why? Imagine uploading file with "rm -rf /" line in it.]
+
+#CWD /somewhere
+cd /somewhere; echo '### 000'
+
+It is specified here, but I'm not sure how wise idea is to use this
+one: it breaks stateless-ness of the protocol.
+
+Following commands should be rather self-explanatory:
+
+#CHMOD 1234 file
+chmod 1234 file; echo '### 000'
+
+#DELE /some/path
+rm -f /some/path; echo '### 000'
+
+#MKD /some/path
+mkdir /some/path; echo '### 000'
+
+#RMD /some/path
+rmdir /some/path; echo '### 000'
+
+#RENAME /path/a /path/b
+mv /path/a /path/b; echo '### 000'
+
+#LINK /path/a /path/b
+ln /path/a /path/b; echo '### 000'
+
+#SYMLINK /path/a /path/b
+ln -s /path/a /path/b; echo '### 000'
+
+#CHOWN user /file/name
+chown user /file/name; echo '### 000'
+
+#CHGRP group /file/name
+chgrp group /file/name; echo '### 000'
+
+#INFO
+...collect info about host into $result ...
+echo $result
+echo '### 200'
+
+#READ <offset> <size> /path/and/filename
+cat /path/and/filename | ( dd bs=4096 count=<offset/4096> > /dev/null;
+dd bs=<offset%4096> count=1 > /dev/null;
+dd bs=4096 count=<offset/4096>;
+dd bs=<offset%4096> count=1; )
+
+Returns ### 200 on successful exit, ### 291 on successful exit when
+reading ended at eof, ### 292 on successful exit when reading did not
+end at eof.
+
+#WRITE <offset> <size> /path/and/filename
+
+Hmm, shall we define these ones if we know our client is not going to
+use them?
+
+you can use follow parameters:
+FISH_FILESIZE
+FISH_FILENAME
+FISH_FILEMODE
+FISH_FILEOWNER
+FISH_FILEGROUPE
+FISH_FILEFROM
+FISH_FILETO
+
+NB:
+'FISH_FILESIZE' used if we operate with single file name in 'unlink', 'rmdir', 'chmod', etc...
+'FISH_FILEFROM','FISH_FILETO'  used if we operate with two files in 'ln', 'hardlink', 'mv' etc...
+'FISH_FILEOWNER', 'FISH_FILEGROUPE' is a new user/group in chown
+
+also flags:
+FISH_HAVE_HEAD
+FISH_HAVE_SED
+FISH_HAVE_AWK
+FISH_HAVE_PERL
+FISH_HAVE_LSQ
+FISH_HAVE_DATE_MDYT
+
+That's all, folks!

+ *
+ * \todo
+- make it more robust - all the connects etc. should handle EADDRINUSE and
+  ERETRY (have I spelled these names correctly?)
+- make the user able to flush a connection - all the caches will get empty
+  etc., (tarfs as well), we should give there a user selectable timeout
+  and assign a key sequence.
+- use hash table instead of linklist to cache ftpfs directory.
+
+What to do with this?
+
+
+     * NOTE: Usage of tildes is deprecated, consider:
+     * \verbatim
+         cd ftp//:pavel@hobit
+         cd ~
+       \endverbatim
+     * And now: what do I want to do? Do I want to go to /home/pavel or to
+     * ftp://hobit/home/pavel? I think first has better sense...
+     *

+ * suffix, DON'T try to gunzip it yourself.

+   The sparse file information is stored in the oldgnu_header in the following manner:
+
+   The header is marked with type 'S'. Its 'size' field contains the cumulative size
+   of all non-empty blocks of the file. The actual file size is stored in `realsize'
+   member of oldgnu_header.
+
+   The map of the file is stored in a list of 'struct sparse'. Each struct contains
+   offset to the block of data and its size (both as octal numbers). The first file
+   header contains at most 4 such structs (SPARSES_IN_OLDGNU_HEADER). If the map
+   contains more structs, then the field 'isextended' of the main header is set to
+   1 (binary) and the 'struct sparse_header' header follows, containing at most
+   21 following structs (SPARSES_IN_SPARSE_HEADER). If more structs follow, 'isextended'
+   field of the extended header is set and next  next extension header follows, etc...

+/* GNU PAX sparse file format. There are several versions:
+ * 0.0
+
+ The initial version of sparse format used by tar 1.14-1.15.1.
+ The sparse file map is stored in x header:
+
+ GNU.sparse.size      Real size of the stored file
+ GNU.sparse.numblocks Number of blocks in the sparse map repeat numblocks time
+ GNU.sparse.offset    Offset of the next data block
+ GNU.sparse.numbytes  Size of the next data block end repeat
+
+ This has been reported as conflicting with the POSIX specs. The reason is
+ that offsets and sizes of non-zero data blocks were stored in multiple instances
+ of GNU.sparse.offset/GNU.sparse.numbytes variables, whereas POSIX requires the
+ latest occurrence of the variable to override all previous occurrences.
+
+ To avoid this incompatibility two following versions were introduced.
+
+ * 0.1
+
+ Used by tar 1.15.2 -- 1.15.91 (alpha releases).
+
+ The sparse file map is stored in x header:
+
+ GNU.sparse.size      Real size of the stored file
+ GNU.sparse.numblocks Number of blocks in the sparse map
+ GNU.sparse.map       Map of non-null data chunks. A string consisting of comma-separated
+ values "offset,size[,offset,size]..."
+
+ The resulting GNU.sparse.map string can be *very* long. While POSIX does not impose
+ any limit on the length of a x header variable, this can confuse some tars.
+
+ * 1.0
+
+ Starting from this version, the exact sparse format version is specified explicitly
+ in the header using the following variables:
+
+ GNU.sparse.major     Major version 
+ GNU.sparse.minor     Minor version
+
+ X header keeps the following variables:
+
+ GNU.sparse.name      Real file name of the sparse file
+ GNU.sparse.realsize  Real size of the stored file (corresponds to the old GNU.sparse.size
+ variable)
+
+ The name field of the ustar header is constructed using the pattern "%d/GNUSparseFile.%p/%f".
+
+ The sparse map itself is stored in the file data block, preceding the actual file data.
+ It consists of a series of octal numbers of arbitrary length, delimited by newlines.
+ The map is padded with nulls to the nearest block boundary.
+
+ The first number gives the number of entries in the map. Following are map entries, each one
+ consisting of two numbers giving the offset and size of the data block it describes.
+
+ The format is designed in such a way that non-posix aware tars and tars not supporting
+ GNU.sparse.* keywords will extract each sparse file in its condensed form with the file map
+ attached and will place it into a separate directory. Then, using a simple program it would be
+ possible to expand the file to its original form even without GNU tar.
+
+ Bu default, v.1.0 archives are created. To use other formats, --sparse-version option is provided.
+ Additionally, v.0.0 can be obtained by deleting GNU.sparse.map from 0.1 format:
+ --sparse-version 0.1 --pax-option delete=GNU.sparse.map

+ *
+ * Assumptions:
+ *
+ * 1. We don't handle directories (thus undelfs_get_path is easy to write).
+ * 2. Files are on the local file system (we do not support vfs files
+ *    because we would have to provide an io_manager for the ext2fs tools,
+ *    and I don't think it would be too useful to undelete files
