a stopped queue, `queue start' to run it, `queue stop' to stop
it. When you exit lftp, the queue will start automatically.

with a slash.

some changes by me (strongly buildlinked now).
ATTENTION: If package compilation is failing for you on -current in the
linking step, make sure you have /usr/include/libintl.h v1.2 (2001/08/13)!
[Thanks for the tip, Johnny!]
Some of the changes since 2.3.9 (for a complete log see ${WRKSRC}/NEWS):
* sometimes lftp did not expand tilde in remote path - fixed.
* new setting ftp:home to specify starting directory explicitly. Set it
to `/' to override RFC1738 ftp url semantics if you don't like the
look of `ftp://host/%2Fpath'.
* improved abort sequence for passive mode, now wu-ftpd does not hang.
* fish protocol support (over plain ssh connection).
* use CONNECT method for https over http proxy.
* support for variable name completion (Nicolas Noble).
* queue editing support (Glenn F. Maynard).
* support http keep-alive in case of chunked transfer encoding.
* terminate some never-ending jobs before moving to background.
* support for HTTP/1.1 416 reply code.
* support for ftp ACCT command (ftp:acct variable) and for SITE GROUP command
(ftp:site-group variable). E.g. `set ftp:acct/user@host account/password'.
* new setting ftp:port-ipv4 to specify explicitly IP address sent with PORT
command (suggested by Julien Oster and Jonas Jensen with patches).
* new setting ftp:ssl-auth to specify AUTH argument to use (SSL, TLS, TLS-C
or TLS-P).
* roxen directory listing support.
* new settings ftp:retry-530 and ftp:retry-530-anonymous. Retry on server
reply 530 for PASS command if text matches these regular expressions.
These settings should be useful to distinguish between overloaded server
(temporary condition) and incorrect password (permanent condition).
* retry ftp login quickly on next address if the server has many (works
well on ftp.redhat.com, for example).
* improved fuzzy variable name matching. Exact prefix and exact name after
prefix are taken into account separately. E.g. http:pro is not ambigous
now between http:proxy and https:proxy.
* implemented -c option for reverse mirror (mirror -R -c).
* allow open "" to switch to disconnected dummy session.
* allow adding bookmark for disconnected dummy session.
* new translation zh_TW (by R.I.P. Deaddog <maddog@linuxhall.org>).
* made `lftp@' the default ftp password.
As well as many bug fixes and translation updates.
* new setting ftp:bind-data-socket (bool) to disable binding of local end
of data connection in passive mode.
* https and ftps protocols support (openssl library is needed for that).
* completion now appends a slash to remote directories (finally!).
* new mirror option --parallel=[N] to download several files in parallel.
* ask for password for ftp:proxy if not supplied.
* now if you set ftp:proxy to http://proxy.host:port, hftp will be used
automatically instead of ftp, but pwd will still show ftp://.
* large file (>2G) support added.
* full http keep-alive support.
* new settings http:put-method (PUT or POST), http:put-content-type,
http:post-content-type.
* new setting xfer:max-redirections for http redirections following.
* automatic cookie accepting (off by default). New setting http:set-cookies.
* two http specific quote commands: `quote set-cookie' and `quote post'.
(e.g. `quote set-cookie var=value' or `quote post /cgi-bin/script.cgi
var=value > output'.
* send encoded path in http protocol as it was entered by user in URL.
(e.g. `get http://www.server.net/abc.cgi?arg=cba -o cba')
* new settings http:accept, http:accept-charset, http:accept-language.
* new setting cmd:move-background to disable automatic moving to background;
`exit bg' forces moving to background.
* `wait all' waits for termination of all jobs.
* show QUIT reply in debug output.
* new setting ftp:use-quit.
* new setting net:persist-retries (ignore this number of hard errors).
* new setting ftp:auto-sync-mode (extended regex) to match first server reply.
* try to connect to original IP when PASV returns address from private
network and original IP is not in private network.
* add workarounds for hftp over apache proxy.
* use getipnodebyname or getaddrinfo when gethostbyname2 is unavailable.
and a lot of bugfixes.
