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.

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.
