-# zftp is a loadable module implementing an FTP client as a builtin
-# command so that you can use the shell command language and line
-# editing to make life easier.  If your system has dynamically
-# load libraries and zsh was compiled to use them, it is probably
-# somewhere where it can be loaded at run time.  Otherwise, it depends
-# whether the shell was compiled with zftp already built into it.
-#
-# Here is a suite of functions, plus assorted other code, to make
-# zftp work smoothly.
-#
-# Completion is implemented in a fairly natural way, except that
-# very little support has been provided for non-UNIX remote hosts.
-# On such machines, the safest thing to do is only try to complete
-# files in the current directory; this should be OK.
-#
-# Remote globbing for commands which retrieve files is also
-# implemented.  This can be done in two different ways.  The default
-# is for zsh to do the globbing locally.  The advantage is that full
-# zsh pattern matching (respecting the setting of extendedglob) is
-# possible, and no assumption (apart from the restrictions on
-# directory handling noted above) is made about the behaviour of the
-# server.  The disadvantage is that the entire filename list for the
-# current directory must be retrieved, and then zsh must laboriously
-# do pattern matching against every file, so it is potentially slow
-# for large directories.  Only the non-directory part of file names is
-# globbed.
-#
-# The alternative will be used if $zfrglob has non-zero length.
-# Zsh then sends the pattern to the server for globbing.  Best of
-# luck.
-#
-# To support remote globbing, some functions have been aliased
-# with 'noglob' in front.  Currently, this has a dire effect on
-# completion unless the completeinaliases option is set, so
-# it is set below.  This can conceivably cause you problems
-# if you expect completion for aliases automatically to give you
-# completion for the base command.  I suspect that most people
-# don't even know that happens.
-#
-# The following functions are provided.
-#
-# General status changing and displaying functions:
-# zfparams
-#   Simple front end to `zftp params', except it will automatically
-#   query host, user and password.  These are then stored to be
-#   used with a `zfopen' with no arguments.
-# zfopen [ host [ user ... ] ]
-#   Open a connection and login.  Unless the option -1 (once)
-#   is given, will store the parameters for the open (including
-#   a password which is prompted for and not echoed) so that
-#   if you call zfopen subsequently without arguments it will
-#   reopen the same connection.
-# zfanon anonftphost
-#   Open a connection for anonymous FTP.  Tries to guess an
-#   email address to use as the password, unless $EMAIL_ADDR is
-#   already set.  The first time, will tell you what it has guessed.
-#   It's rude to set EMAIL_ADDR=mozilla.
-# zfcd [ dir | old new ]
-#   Change directory on the server.  This tries to mimic the behaviour
-#   of the shell's cd.  In particular,
-#    zfcd           change to '~' on server, if it interprets it
-#    zfcd -         change to previous directory of current connection
-#    zfcd OLD NEW   change directory from fooOLDbar to fooNEWbar
-#   One piece of magic is builtin:  an initial part of the directory
-#   matching $HOME is translated back to `~'.  Most UNIX servers
-#   recognise the usual shell convention.  So things like `zfcd $PWD'
-#   is useful provide you are under your home directory and the
-#   structure on the remote machine mirrors that on the local.
-# zfhere
-#   Synonym for `zfcd $PWD', see above.
-# zfdir [args]
-#   Show a long diretory list of the remote connection.  Any
-#   arguments are passed on to the server, apart from options.
-#   Currently this always uses a pager to show the directory
-#   list.  Caching is implemented:  zfdir on its own always shows
-#   the current diretory, which is cached; zfdir with some other
-#   directory arguments shows that, which is cached separately
-#   and can be reviewed with `zfdir -r'.  Other options:
-#    -f  force reget, overriding the cache, in case something's changed
-#    -d  delete the cache, but don't show anything.
-#   To pass options to the server, use e.g. `zfdir -- -C'.
-#   This also has the zfcd ~ hack.
-# zfls [args]
-#   Short list of the long directory, depending on what [args]
-#   do to the server.  No options, no caching, no pager.
-# zftype [ a[scii] | i[mage] | b[inary] ]
-#   Set or display the transfer type; currently only ASCII
-#   and image (same as binary) types are supported.
-# zfclose
-#   Close the connection.
-# zfstat
-#   Print the zftp status from local variables; doesn't do any network
-#   operations unless -v is supplied, in which case the server is
-#   asked for its views on the status, too.
-#
-# Functions for retrieving data:
-#   All accept the following options:
-#    -G   Don't do remote globbing (see above); the default is to do it.
-#    -t   Try to set local files to the same time as the remote ones.
-#         Unfortunately we only know the remote time in GMT, so it's
-#         a little tricky and you need perl 5 (installed as `perl')
-#         for this to work.  Suggestions welcome.
-# zfget file1 file2 ...
-#   Retrieve each file from the server.  The remote file is the
-#   full name given, the local file is the non-directory part of that
-#   (assuming UNIX file paths).
-# zfuget file1 file2 ..
-#   Get with update.  Check remote and local sizes and times and
-#   retrieve files which are newer on the server.  Will query
-#   hard cases, which are where the remote file is newer but a
-#   different size, or is older but the same size.  With option -s
-#   (silent) assumes it's best to retrieve the files in both those
-#   cases.  With -v (may be combined with -s), print the information
-#   about the files being considered.
-# zfcget file1 ...
-#   Assuming file1 was incompletely retrieved, try to get the rest of
-#   it.  This relies on a normal UNIX server behaviour which is not
-#   as specified in the FTP standard and hence is not universal.
-# zfgcp file1 file2
-# zfgcp file1 file2 ... dir
-#   Get with the behaviour of cp, i.e. copy remote file1 to local
-#   file2, or get remote fileN into local diretory dir.
-#
-# Function for sending data:
-# zfput file1 file2 ...
-#   Put the local files onto the server under the same name.  The
-#   local files are exactly as given; the remote files are the
-#   non-diretory parts of that. 
-# zfuput file1 file2 ..
-#   Put the local files onto the server, with update.  Works
-#   similarly to zfuget.
-#
-# Utility functions:
-# zftp_chpwd
-#   Show the new directory when it changes; try to put it into
-#   an xterm on shelltool header.  Works best alongside chpwd.
-# zftp_progress
-#   Show the percentage of a file retrieved as it is coming; if the
-#   size is not available show the size transferred so far.  The
-#   percentage may be wrong if sending data from a local pipe.
-#   If you transfer files in the background, you should undefine
-#   this before the transfer.  It is smart enough not to print
-#   anything when stderr is not a terminal.
-# zfcd_match
-#   Function for remote directory completion.
-# zfget_match
-#   Function for remote filename completion.
-# zfrglob varname
-#   This is used for the remote globbing.  The pattern resides
-#   in $varname (note extra level of indirection), and on return
-#   $varname will contain the list of matching files.
-# zfrtime locfile remfile [ time ]
