-## This is "webget"
-##
-## Jeffrey Friedl (jfriedl@omron.co.jp), July 1994.
-## Copyright 19.... ah hell, just take it.
-## Should work with either perl4 or perl5
-##
-## BLURB:
-## Given a URL on the command line (HTTP and FTP supported at the moment),
-## webget fetches the named object (HTML text, images, audio, whatever the
-## object happens to be). Will automatically use a proxy if one is defined
-## in the environment, follow "this URL has moved" responses, and retry
-## "can't find host" responses from a proxy in case host lookup was slow).
-## Supports users & passwords (FTP), Basic Authorization (HTTP), update-if-
-## modified (HTTP), and much more. Works with perl4 or perl5.
-
-##
-## More-detailed instructions in the comment block below the history list.
-##
-
-##
-## To-do:
-## Add gopher support.
-## Fix up how error messages are passed among this and the libraries.
-##
-
-## 951219.19
-## Lost ftp connections now die with a bit more grace.
-##
-## 951121.18
-## Add -nnab.
-## Brought the "usage" string in line with reality.
-##
-## 951114.17
-## Added -head.
-## Added -update/-refresh/-IfNewerThan. If any URL was not pulled
-## because it was not out of date, an exit value of 2 is returned.
-##
-## 951031.16
-## Added -timeout. Cleaned up (a bit) the exit value. Now exits
-## with 1 if all URLs had some error (timeout exits immediately with
-## code 3, though. This is subject to change). Exits with 0 if any
-## URL was brought over safely.
-##
-## 951017.15
-## Neat -pf, -postfile idea from Lorrie Cranor
-## (http://www.ccrc.wustl.edu/~lorracks/)
-##
-## 950912.14
-## Sigh, fixed a typo.
-##
-## 950911.13
-## Added Basic Authorization support for http. See "PASSWORDS AND STUFF"
-## in the documentation.
-##
-## 950911.12
-## Implemented a most-excellent suggestion by Anthony D'Atri
-## (aad@nwnet.net), to be able to automatically grab to a local file of
-## the same name as the URL. See the '-nab' flag.
-##
-## 950706.11
-## Quelled small -w warning (thanks: Lars Rasmussen <gnort@daimi.aau.dk>)
-##
-## 950630.10
-## Steve Campbell to the rescue again. FTP now works when supplied
-## with a userid & password (eg ftp://user:pass@foo.bar.com/index.txt).
-##
-## 950623.9
-## Incorporated changes from Steve Campbell (steven_campbell@uk.ibm.com)
-## so that the ftp will work when no password is required of a user.
-##
-## 950530.8
-## Minor changes:
-## Eliminate read-size warning message when size unknown.
-## Pseudo-debug/warning messages at the end of debug_read now go to
-## stderr. Some better error handling when trying to contact systems
-## that aren't really set up for ftp. Fixed a bug concerning FTP access
-## to a root directory. Added proxy documentation at head of file.
-##
-## 950426.6,7
-## Complete Overhaul:
-## Renamed from httpget. Added ftp support (very sketchy at the moment).
-## Redid to work with new 'www.pl' library; chucked 'Www.pl' library.
-## More or less new and/or improved in many ways, but probably introduced
-## a few bugs along the way.
-##
-## 941227.5
-## Added follow stuff (with -nofollow, etc.)
-## Added -updateme. Cool!
-## Some general tidying up.
-##
-## 941107.4
-## Allowed for ^M ending a header line... PCs give those kind of headers.
-##
-## 940820.3
-## First sorta'clean net release.
-##
-##
-
-##
-##>
-##
-## Fetch http and/or ftp URL(s) given on the command line and spit to
-## STDOUT.
-##
-## Options include:
-## -V, -version
-## Print version information; exit.
-##
-## -p, -post
-## If the URL looks like a reply to a form (i.e. has a '?' in it),
-## the request is POST'ed instead of GET'ed.
-##
-## -head
-## Gets the header only (for HTTP). This might include such useful
-## things as 'Last-modified' and 'Content-length' fields
-## (a lack of a 'Last-modified' might be a good indication that it's
-## a CGI).
-##
-## The "-head" option implies "-nostrip", but does *not* imply,
-## for example "-nofollow".
-##
-##
-## -pf, -postfile
-## The item after the '?' is taken as a local filename, and the contents
-## are POST'ed as with -post
-##
-## -nab, -f, -file
-## Rather than spit the URL(s) to standard output, unconditionally
-## dump to a file (or files) whose name is that as used in the URL,
-## sans path. I like '-nab', but supply '-file' as well since that's
-## what was originally suggested. Also see '-update' below for the
-## only-if-changed version.
-##
-## -nnab
-## Like -nab, but in addtion to dumping to a file, dump to stdout as well.
-## Sort of like the 'tee' command.
-##
-## -update, -refresh
-## Do the same thing as -nab, etc., but does not bother pulling the
-## URL if it older than the localfile. Only applies to HTTP.
-## Uses the HTTP "If-Modified-Since" field. If the URL was not modified
-## (and hence not changed), the return value is '2'.
-##
-## -IfNewerThan FILE
-## -int FILE
-## Only pulls URLs if they are newer than the date the local FILE was
-## last written.
-##
-## -q, -quiet
-## Suppresses all non-essential informational messages.
-##
-## -nf, -nofollow
-## Normally, a "this URL has moved" HTTP response is automatically
-## followed. Not done with -nofollow.
-##
-## -nr, -noretry
-## Normally, an HTTP proxy response of "can't find host" is retried
-## up to three times, to give the remote hostname lookup time to
-## come back with an answer. This suppresses the retries. This is the
-## same as '-retry 0'.
-##
-## -r#, -retry#, -r #, -retry #
-## Sets the number of times to retry. Default 3.
-##
-## -ns, -nostrip
-## For HTTP items (including other items going through an HTTP proxy),
-## the HTTP response header is printed rather than stripped as default.
-##
-## -np, -noproxy
-## A proxy is not used, even if defined for the protocol.
-##
-## -h, -help
-## Show a usage message and exit.
-##
-## -d, -debug
-## Show some debugging messages.
-##
-## -updateme
-## The special and rather cool flag "-updateme" will see if webget has
-## been updated since you got your version, and prepare a local
-## version of the new version for you to use. Keep updated! (although
-## you can always ask to be put on the ping list to be notified when
-## there's a new version -- see the author's perl web page).
-##
-## -timeout TIMESPAN
-## -to TIMESPAN
-## Time out if a connection can not be made within the specified time
-## period. TIMESPAN is normally in seconds, although a 'm' or 'h' may
-## be appended to indicate minutes and hours. "-to 1.5m" would timeout
-## after 90 seconds.
-##
-## (At least for now), a timeout causes immediate program death (with
-## exit value 3). For some reason, the alarm doesn't always cause a
-## waiting read or connect to abort, so I just die immediately.. /-:
-##
-## I might consider adding an "entire fetch" timeout, if someone
-## wants it.
-##
-## PASSWORDS AND SUCH
-##
-## You can use webget to do FTP fetches from non-Anonymous systems and
-## accounts. Just put the required username and password into the URL,
-## as with
-## webget 'ftp:/user:password@ftp.somesite.com/pub/pix/babe.gif
-## ^^^^^^^^^^^^^
-## Note the user:password is separated from the hostname by a '@'.
-##
-## You can use the same kind of thing with HTTP, and if so it will provide
-## what's know as Basic Authorization. This is >weak< authorization. It
-## also provides >zero< security -- I wouldn't be sending any credit-card
-## numbers this way (unless you send them 'round my way :-). It seems to
-## be used most by providers of free stuff where they want to make some
-## attempt to limit access to "known users".
-##
-## PROXY STUFF
-##
-## If you need to go through a gateway to get out to the whole internet,
-## you can use a proxy if one's been set up on the gateway. This is done
-## by setting the "http_proxy" environmental variable to point to the
-## proxy server. Other variables are used for other target protocols....
-## "gopher_proxy", "ftp_proxy", "wais_proxy", etc.
-##
-## For example, I have the following in my ".login" file (for use with csh):
-##
-## setenv http_proxy http://local.gateway.machine:8080/
-##
-## This is to indicate that any http URL should go to local.gateway.machine
-## (port 8080) via HTTP. Additionally, I have
-##
-## setenv gopher_proxy "$http_proxy"
-## setenv wais_proxy "$http_proxy"
-## setenv ftp_proxy "$http_proxy"
-##
-## This means that any gopher, wais, or ftp URL should also go to the
-## same place, also via HTTP. This allows webget to get, for example,
-## GOPHER URLs even though it doesn't support GOPHER itself. It uses HTTP
-## to talk to the proxy, which then uses GOPHER to talk to the destination.
-##
-## Finally, if there are sites inside your gateway that you would like to
-## connect to, you can list them in the "no_proxy" variable. This will allow
-## you to connect to them directly and skip going through the proxy:
-##
-## setenv no_proxy "www.this,www.that,www.other"
-##
-## I (jfriedl@omron.co.jp) have little personal experience with proxies
-## except what I deal with here at Omron, so if this is not representative
-## of your situation, please let me know.
-##
-## RETURN VALUE
-## The value returned to the system by webget is rather screwed up because
-## I didn't think about dealing with it until things were already
-## complicated. Since there can be more than one URL on the command line,
-## it's hard to decide what to return when one times out, another is fetched,
-## another doesn't need to be fetched, and a fourth isn't found.
-##
-## So, here's the current status:
-##
-## Upon any timeout (via the -timeout arg), webget immediately
-## returns 3. End of story. Otherwise....
-##
-## If any URL was fetched with a date limit (i.e. via
-## '-update/-refresh/-IfNewerThan' and was found to not have changed,
-## 2 is returned. Otherwise....
-##
-## If any URL was successfully fetched, 0 is returned. Otherwise...
-##
-## If there were any errors, 1 is returned. Otherwise...
-##
-## Must have been an info-only or do-nothing instance. 0 is returned.
-##
-## Phew. Hopefully useful to someone.

- Fetches and displays the named URL(s). Supports http and ftp.
- (if no protocol is given, a leading "http://" is normally used).

-Options are from among:
- -V, -version Print version information; exit.
- -p, -post If URL looks like a form reply, does POST instead of GET.
- -pf, -postfile Like -post, but takes everything after ? to be a filename.
- -q, -quiet All non-essential informational messages are suppressed.
- -nf, -nofollow Don't follow "this document has moved" replies.
- -nr, -noretry Doesn't retry a failed hostname lookup (same as -retry 0)
- -r #, -retry # Sets failed-hostname-lookup-retry to # (default $retry)
- -np, -noproxy Uses no proxy, even if one defined for the protocol.
- -ns, -nostrip The HTTP header, normally elided, is printed.
- -head gets item header only (implies -ns)
- -nab, -file Dumps output to file whose name taken from URL, minus path
- -nnab Like -nab, but *also* dumps to stdout.
- -update HTTP only. Like -nab, but only if the page has been modified.
- -h, -help Prints this message.
- -IfNewerThan F HTTP only. Only brings page if it is newer than named file.
- -timeout T Fail if a connection can't be made in the specified time.

-## version 950425.4

-## A group of routines for dealing with URLs, HTTP sessions, proxies, etc.
-## Requires my 'network.pl' package. The library file can be executed
-## directly to produce a man page.
-
-##>
-## A motley group of routines for dealing with URLs, HTTP sessions, proxies,
-## etc. Requires my 'network.pl' package.
-##
-## Latest version, as well as other stuff (including network.pl) available
-## at http://www.wg.omron.co.jp/~jfriedl/perl/
-##
-## Simpleton complete program to dump a URL given on the command-line:
-##
-## require 'network.pl'; ## required for www.pl
-## require 'www.pl'; ## main routines
-## $URL = shift; ## get URL
-## ($status, $memo) = &www'open_http_url(*IN, $URL); ## connect
-## die "$memo\n" if $status ne 'ok'; ## report any error
-## print while <IN>; ## dump contents
-##
-## There are various options available for open_http_url.
-## For example, adding 'quiet' to the call, i.e. vvvvvvv-----added
-## ($status, $memo) = &www'open_http_url(*IN, $URL, 'quiet');
-## suppresses the normal informational messages such as "waiting for data...".
-##
-## The options, as well as the various other public routines in the package,
-## are discussed below.

-##
-## A "URL" to "ftp.blah.com" without a protocol specified is probably
-## best reached via ftp. If the hostname begins with a protocol name, it's
-## easy. But something like "www." maps to "http", so that mapping is below:

-## routine: open_http_url
-##
-## Used as
-## ($status, $memo, %info) = &www'open_http_url(*FILEHANDLE, $URL, options..)
-##
-## Given an unused filehandle, a URL, and a list of options, opens a socket
-## to the URL and returns with the filehandle ready to read the data of the
-## URL. The HTTP header, as well as other information, is returned in %info.
-##
-## OPTIONS are from among:
-##
-## "post"
-## If PATH appears to be a query (i.e. has a ? in it), contact
-## via a POST rather than a GET.
-##
-## "nofollow"
-## Normally, if the initial contact indicates that the URL has moved
-## to a different location, the new location is automatically contacted.
-## "nofollow" inhibits this.
-##
-## "noproxy"
-## Normally, a proxy will be used if 'http_proxy' is defined in the
-## environment. This option inhibits the use of a proxy.
-##
-## "retry"
-## If a host's address can't be found, it may well be because the
-## nslookup just didn't return in time and that retrying the lookup
-## after a few seconds will succeed. If this option is given, will
-## wait five seconds and try again. May be given multiple times to
-## retry multiple times.
-##
-## "quiet"
-## Informational messages will be suppressed.
-##
-## "debug"
-## Additional messages will be printed.
-##
-## "head"
-## Requests only the file header to be sent
-##
-##
-##
-##
-## The return array is ($STATUS, $MEMO, %INFO).
-##
-## STATUS is 'ok', 'error', 'status', or 'follow'
-##
-## If 'error', the MEMO will indicate why (URL was not http, can't
-## connect, etc.). INFO is probably empty, but may have some data.
-## See below.
-##
-## If 'status', the connnection was made but the reply was not a normal
-## "OK" successful reply (i.e. "Not found", etc.). MEMO is a note.
-## INFO is filled as noted below. Filehandle is ready to read (unless
-## $info{'BODY'} is filled -- see below), but probably most useful
-## to treat this as an 'error' response.
-##
-## If 'follow', MEMO is the new URL (for when 'nofollow' was used to
-## turn off automatic following) and INFO is filled as described
-## below. Unless you wish to give special treatment to these types of
-## responses, you can just treat 'follow' responses like 'ok'
-## responses.
-##
-## If 'ok', the connection went well and the filehandle is ready to
-## read.
-##
-## INFO contains data as described at the read_http_header() function (in
-## short, the HTTP response header) and additional informational fields.
-## In addition, the following fields are filled in which describe the raw
-## connection made or attempted:
-##
-## PROTOCOL, HOST, PORT, PATH
-##
-## Note that if a proxy is being used, these will describe the proxy.
-## The field TARGET will describe the host or host:port ultimately being
-## contacted. When no proxy is being used, this will be the same info as
-## in the raw connection fields above. However, if a proxy is being used,
-## it will refer to the final target.
-##
-## In some cases, the additional entry $info{'BODY'} exists as well. If
-## the result-code indicates an error, the body of the message may be
-## parsed for internal reasons (i.e. to support 'repeat'), and if so, it
-## will be saved in $info{'BODY}.
-##
-## If the URL has moved, $info{'NewURL'} will exist and contain the new
-## URL. This will be true even if the 'nofollow' option is specified.

-##
-## Upper-case fields:
-##

-##
-## $info{'CODE'} will be the numeric HTTP reply code from that line.
-## This is also returned as $replycode.
-##
-## $info{'TYPE'} is the text from the status line that follows CODE.

-## newlines and all.
-##
-## $info{'UNKNOWN'}, if defined, will be any header lines not in the
-## field/value format used to fill the lower-case fields of %info.
-##
-## Lower-case fields are reply-dependent, but in general are described
-## in http://info.cern.ch/hypertext/WWW/Protocols/HTTP/Object_Headers.html

-## $info{'TYPE'} is 'empty'
-## No response was received from the filehandle before it was closed.
