+# we need to draw a dependency tree and do the leaves first. This can
+# easily be reached by running CPAN.pm recursively, but we don't want
+# to waste memory and run into deep recursion. So what we can do is
+# this:
+
+# CPAN::Queue is the package where the queue is maintained. Dependencies
+# often have high priority and must be brought to the head of the queue,
+# possibly by jumping the queue if they are already there. My first code
+# attempt tried to be extremely correct. Whenever a module needed
+# immediate treatment, I either unshifted it to the front of the queue,
+# or, if it was already in the queue, I spliced and let it bypass the
+# others. This became a too correct model that made it impossible to put
+# an item more than once into the queue. Why would you need that? Well,
+# you need temporary duplicates as the manager of the queue is a loop
+# that
+#
+# (1) looks at the first item in the queue without shifting it off
+#
+# (2) cares for the item
+#
+# (3) removes the item from the queue, *even if its agenda failed and
+# even if the item isn't the first in the queue anymore* (that way
+# protecting against never ending queues)
+#
+# So if an item has prerequisites, the installation fails now, but we
+# want to retry later. That's easy if we have it twice in the queue.
+#
+# I also expect insane dependency situations where an item gets more
+# than two lives in the queue. Simplest example is triggered by 'install
+# Foo Foo Foo'. People make this kind of mistakes and I don't want to
+# get in the way. I wanted the queue manager to be a dumb servant, not
+# one that knows everything.
+#
+# Who would I tell in this model that the user wants to be asked before
+# processing? I can't attach that information to the module object,
+# because not modules are installed but distributions. So I'd have to
+# tell the distribution object that it should ask the user before
+# processing. Where would the question be triggered then? Most probably
+# in CPAN::Distribution::rematein.

+Or if you want to write a cronjob to watch The CPAN, you could list
+all modules that need updating:
+
+ perl -e 'use CPAN; CPAN::Shell->r;'
+
+If you don't want to get any output if all modules are up to date, you
+can parse the output of above command for the regular expression
+//modules are up to date// and decide to mail the output only if it
+doesn't match. Ick?
+
+If you prefer to do it more in a programmer style in one single
+process, maybe something like this suites you better:
+
+ # list all modules on my disk that have newer versions on CPAN
+ for $mod (CPAN::Shell->expand("Module","/./")){
+ next unless $mod->inst_file;
+ next if $mod->uptodate;
+ printf "Module %s is installed as %s, could be updated to %s from CPAN\n",
+ $mod->id, $mod->inst_version, $mod->cpan_version;
+ }
+
+If that gives you too much output every day, you maybe only want to
+watch for three modules. You can write
+
+ for $mod (CPAN::Shell->expand("Module","/Apache|LWP|CGI/")){
+
+as the first line instead. Or you can combine some of the above
+tricks:
+
+ # watch only for a new mod_perl module
+ $mod = CPAN::Shell->expand("Module","mod_perl");
+ exit if $mod->uptodate;
+ # new mod_perl arrived, let me know all update recommendations
+ CPAN::Shell->r;

=head2 Cache Manager

It starts like a perl module with a package declaration and a $VERSION
variable. After that the pod section looks like any other pod with the

+(e.g. Foo::Bar, ie. I<not> the name of the distribution file). The rest
of the line is optional. The comment part is delimited by a dash just
as in the man page header.
Bundles are treated specially in the CPAN package. If you say 'install
Bundle::Tkkit' (assuming such a bundle exists), CPAN will install all
-the modules in the CONTENTS section of the pod. You can install your
+the modules in the CONTENTS section of the pod. You can install your
own Bundles locally by placing a conformant Bundle file somewhere into
your @INC path. The autobundle() command which is available in the
shell interface does that for you by including all currently installed
modules in a snapshot bundle file.
-There is a meaningless Bundle::Demo available on CPAN. Try to install
-it, it usually does no harm, just demonstrates what the Bundle
-interface looks like.

You can set and query each of these options interactively in the cpan

+=head2 Note on urllist parameter's format
+
+urllist parameters are URLs according to RFC 1738. We do a little
+guessing if your URL is not compliant, but if you have problems with file URLs, please try the correct format. Either:
+
+ file://localhost/whatever/ftp/pub/CPAN/
+
+or
+
+ file:///home/ftp/pub/CPAN/
+
+=head2 urllist parameter has CD-ROM support
+
+The C<urllist> parameter of the configuration table contains a list of
+URLs that are to be used for downloading. If the list contains any
+C<file> URLs, CPAN always tries to get files from there first. This
+feature is disabled for index files. So the recommendation for the
+owner of a CD-ROM with CPAN contents is: include your local, possibly
+outdated CD-ROM as a C<file> URL at the end of urllist, e.g.
+
+ o conf urllist push file://localhost/CDROM/CPAN
+
+CPAN.pm will then fetch the index files from one of the CPAN sites
+that come at the beginning of urllist. It will later check for each
+module if there is a local copy of the most recent version.
+
+Another peculiarity of urllist is that the site that we could
+successfully fetch the last file from automatically gets a preference
+token and is tried as the first site for the next request. So if you
+add a new site at runtime it may happen that the previously preferred
+site will be tried another time. This means that if you want to disallow
+a site for the next transfer, it must be explicitly removed from
+urllist.
+
=head1 SECURITY
There's no strong security layer in CPAN.pm. CPAN.pm helps you to
to a checksum that comes from the net just as the distribution file
itself. If somebody has managed to tamper with the distribution file,
they may have as well tampered with the CHECKSUMS file. Future
-development will go towards strong authentification.
+development will go towards strong authentication.
=head1 EXPORT
for this is that the primary use is intended for the cpan shell or for
oneliners.
+=head1 POPULATE AN INSTALLATION WITH LOTS OF MODULES
+
+To populate a freshly installed perl with my favorite modules is pretty
+easiest by maintaining a private bundle definition file. To get a useful
+blueprint of a bundle definition file, the command autobundle can be used
+on the CPAN shell command line. This command writes a bundle definition
+file for all modules that are installed for the currently running perl
+interpreter. It's recommended to run this command only once and from then
+on maintain the file manually under a private name, say
+Bundle/my_bundle.pm. With a clever bundle file you can then simply say
+
+ cpan> install Bundle::my_bundle
+
+then answer a few questions and then go out for a coffee.
+
+Maintaining a bundle definition file means to keep track of two
+things: dependencies and interactivity. CPAN.pm sometimes fails on
+calculating dependencies because not all modules define all MakeMaker
+attributes correctly, so a bundle definition file should specify
+prerequisites as early as possible. On the other hand, it's a bit
+annoying that many distributions need some interactive configuring. So
+what I try to accomplish in my private bundle file is to have the
+packages that need to be configured early in the file and the gentle
+ones later, so I can go out after a few minutes and leave CPAN.pm
+unattained.
+
+=head1 WORKING WITH CPAN.pm BEHIND FIREWALLS
+
+Thanks to Graham Barr for contributing the following paragraphs about
+the interaction between perl, and various firewall configurations.
+
+Firewalls can be categorized into three basic types.
+
+=over
+
+=item http firewall
+
+This is where the firewall machine runs a web server and to access the
+outside world you must do it via the web server. If you set environment
+variables like http_proxy or ftp_proxy to a values beginning with http://
+or in your web browser you have to set proxy information then you know
+you are running a http firewall.
+
+To access servers outside these types of firewalls with perl (even for
+ftp) you will need to use LWP.
+
+=item ftp firewall
+
+This where the firewall machine runs a ftp server. This kind of firewall will
+only let you access ftp serves outside the firewall. This is usually done by
+connecting to the firewall with ftp, then entering a username like
+"user@outside.host.com"
+
+To access servers outside these type of firewalls with perl you
+will need to use Net::FTP.
+
+=item One way visibility
+
+I say one way visibility as these firewalls try to make themselve look
+invisible to the users inside the firewall. An FTP data connection is
+normally created by sending the remote server your IP address and then
+listening for the connection. But the remote server will not be able to
+connect to you because of the firewall. So for these types of firewall
+FTP connections need to be done in a passive mode.
+
+There are two that I can think off.
+
+=over
+
+=item SOCKS
+
+If you are using a SOCKS firewall you will need to compile perl and link
+it with the SOCKS library, this is what is normally called a ``socksified''
+perl. With this executable you will be able to connect to servers outside
+the firewall as if it is not there.
+
+=item IP Masquerade
+
+This is the firewall implemented in the Linux kernel, it allows you to
+hide a complete network behind one IP address. With this firewall no
+special compiling is need as you can access hosts directly.
