NAME
   Linux::APT - Interface with APT for Debian distributions

DESCRIPTION
   Perl interface to "apt-get" and "apt-cache". If Debian's "aptpkg"
   modules were on CPAN, this module (probably) wouldn't be necessary. This
   is just a wrapper around the "apt" tools along with some regular
   expression magic to capture interesting pieces of
   information/warnings/errors in the process. It doesn't do *everything*
   that is possible, but it should fill the most typical needs. Features
   will be added on request or my own need. Please file a wishlist bug
   report on the CPAN bug tracker with your feature requests.

   All (or almost all?) features require root privileges. If you can use
   "sudo" to provide this functionality, see "new" to see how to do this.

   It's not ready for production use, but you're welcome to give it a try.
   *Please* file bug reports if you come across any problems/bugs/etc.
   Patches are always welcomed, of course.

EXAMPLE
     my $apt = Linux::APT->new;
     my $update = $apt->update;
     my $toupgrade = $apt->toupgrade;
     my $upgraded = $apt->install(keys(%{$toupgrade->{packages}}));

METHODS
 new
     my $apt = Linux::APT->new;

     # only if you _really_ want to see what's going on...
     my $apt = Linux::APT->new(debug => 1);

     # if you want to use an alternate apt-get/apt-cache binary
     my $apt = Linux::APT->new(
       aptget => '/some/path/to/apt-get',
       aptcache => '/some/path/to/apt-cache',
     );

     # if you have special needs (like sudo, etc)
     my $apt = Linux::APT->new(
       aptget => '/usr/bin/sudo /some/path/to/apt-get -s', # sudo and no-act
       aptcache => '/usr/bin/sudo /some/path/to/apt-cache', # sudo
     );

   Creates an instance of Linux::APT, just like you would expect.

   If you have special needs for only one function (install maybe?), make a
   separate instance with your special needs (flags, sudo, etc) and use
   that instance for your special need.

   If your special need can't be accommodated via the "aptget" option
   above, let me know and I'll attempt to implement whatever it is that you
   need within the module or make your special need a bit more "accessible"
   to you. File a bug report on the CPAN bug tracker. Patches welcome, of
   course.

   Arguments available:

   debug
       Set to 1 to enable, defaults to 0.

   aptget
       Specify the "apt-get" binary to use along with any special flags or
       command line tricks (sudo, chroot, fakeroot, etc). Defaults to
       `which apt-get`.

   aptcache
       Specify the "apt-cache" binary to use along with any special flags
       or command line tricks (sudo, chroot, fakeroot, etc). Defaults to
       `which apt-cache`.

 update
     my $update = $apt->update;

     warn "There were errors...\n" if $update->{error};
     warn "There were warnings...\n" if $update->{warning};

   Update apt cache. Basically equivalent to "apt-get update".

   Returns hashref containing these items:

   error
       Arrayref of errors.

   warning
       Arrayref of warnings.

   speed
       Network transfer speed of update.

   time
       Wallclock time it took to update.

   size
       Amount of received transferred during update.

 toupgrade
     my $toupgrade = $apt->toupgrade;

   Returns hashref of packages, errors, and warnings:

   warning
       Warnings, if any.

   error
       Errors, if any.

   packages
       Contains a hashref of updateable packages. Keys are package names.
       Each update is a hashref containing these items:

       current
           Currently installed version.

       new Version to be installed.

 search
     my $search = $apt->search('^t\w+d$', 'perl');

     my $search = $apt->search({in => ['all']}, '^t\w+d$', 'perl'); # 'all' is default

     my $search = $apt->search({in=>['name', 'description']},
           'linux[\s-]image', 'linux[\s-]source', 'linux kernel image');

     my $search = $apt->search({in => ['description']}, 'linux kernel source');

   Requires one or more search arguments in regex format. Optional options
   as first argument in hashref format.

   Return a hashref of packages that match the regex search.

   packages
       Multiple searches can be specified. Each search is a hash key then
       broken down by each matching package name and it's summary.

 install
     # install or upgrade the specified packages (and all deps)
     my $install = $apt->install('nautilus', 'libcups2', 'rhythmbox');

     # just a dry run
     my $install = $apt->install('-test', 'nautilus', 'libcups2', 'rhythmbox');

     # upgrade all upgradable packages with a name containing "pulseaudio" (and all deps)
     my $toupgrade = $apt->toupgrade;
     my $install = $apt->install(grep(m/pulseaudio/i, keys(%{$toupgrade->{packages}})));

   Install a list of packages. If the packages are already installed, they
   will be upgraded if an upgrade is available.

   Pass in these optional options:

   -force
       If you wish to force an update (eg: "WARNING: The following packages
       cannot be authenticated!"), pass "-force" as one of your arguments
       (same effect as "apt-get --force-yes install $packages").

   -test
       If you just want to know what packages would be
       installed/upgraded/removed, pass "-test" as one of your arguments.
       No actions will actually take place, only the actions that would
       have been performed will be captured. This is useful when you want
       to ensure some bad thing doesn't happen on accident (like removing
       "apache2-mpm-worker" when you install "php5") or to allow you to
       present the proposed changes to the user via a user interface (GUI,
       webapp, etc).

   Returns hashref of packages, errors, and warnings:

   warning
       Warnings, if any.

   error
       Errors, if any.

   packages
       Contains a hashref of installed/upgraded packages. Keys are package
       names. Each item is a hashref containing these items:

       current
           Currently installed version (after install/upgrade attempt).
           This version is found via an experimental technique and might
           fail (though it has yet to fail for me). Let me know if you find
           a bug or have a problem with this value.

       new Version to be installed. If "new == current", the action seems
           to have succeeded.

       old Version that was installed before the upgrade was performed. If
           "old == current", the action seems to have failed.

 remove
     my $removed = $apt->remove('php5', 'php5-common');

     # just a dry run
     my $removed = $apt->remove('-test', 'php5', 'php5-common');

   Remove a list of packages. Arguments are the exact same as "install".
   Returns the exact same as "install".

 purge
     my $removed = $apt->purge('php5', 'php5-common');

     # just a dry run
     my $removed = $apt->purge('-test', 'php5', 'php5-common');

   Purge a list of packages. Arguments are the exact same as "install".
   Returns the exact same as "install".

TODO
   (update this todo list...)
   Add functions to modify the "sources.list".
   Add "dist-upgrade" functionality.
   Add function to show version(s) of currently installed specified
   package(s).
   Determine other necessary features. (please use the CPAN bug tracker to
   request features)
