+# 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 ]
+#   This sad thing does the setting of local file times to those
+#   of the remote, see horror story above.
