Smart is a package manager that works on most major distros (APT, APT-RPM, YUM, URPMI, etc), and offers "better package management for these distributions, even when working with their own packages".
Smart has been developed with modularity and flexibility in mind. It's completely backend-based, and package-manager-agnostic. Support is currently implemented for RPM, DPKG, and Slackware package management systems, and porting it to new systems should be very easy.
That's one of the most interesting aspects of Smart Package Manager, and the one who has motivated calling it smart: Computing transactions respecting the relations involved in the package management world may become an unpleasant task when thousands of packages and relations are being considered, or even when just a few complex relations turn the most obvious choice into the unwanted one.
While other software applications try to find a possible solution to satisfy the relations involved in some user-requested operation, and sometimes even fail to do so, Smart goes beyond it. In the kernel of Smart Package Manager lives an algorithm that will not only find a solution, if one is available, but will find the best solution. This is done by quickly weighting every possible solution with a pluggable policy, which redefines the term "best" depending on the operation goal (install, remove, upgrade, etc).
This behavior has many interesting consequences. In upgrades, for instance, while precedence is given to newer versions, intermediate versions may get selected if they bring a better global result for the system. Packages may even be reinstalled, if different packages with the same name-version pair have different relations, and the one not installed is considered a better option.
Another important goal achieved with the transaction algorithm is that, even though it is able to check and fix relations in the whole system, it will work even when there are broken relations in installed packages. Only relations related to the operation being made are checked for correctness.
Check case studies for real cases where the algorithm works better than what is implemented in other softwares.
*Priority Handling
Priorities are a powerful way to easily handle integration of multiple channels and explicit user setups regarding preferred package versions.
Basically, packages with higher priorities are considered a better option to be installed in the system, even when package versions state otherwise. Priorities may be individually assigned to all packages in given channels, to all packages with given names, and to packages with given names inside given channels.
With custom priority setups, it becomes possible to avoid unwanted upgrades, force downgrades, select packages in given channels as preferential, and other kinds of interesting setups.
Smart offers a very flexible mirror support. Mirrors are URLs that supposedly provide the same contents as are available in other URLs, named origins. There is no internal restriction on the kind of information which is mirrored. Once an origin URL is provided, and one or more mirror URLs are provided, these mirrors will be considered for any file which is going to be fetched from an URL starting with the origin URL.
Mirror precedence is dynamically computed based on the history of downloads of all mirrors available for a given origin URL (including the origin site itself). The fastest mirrors and with less errors are chosen. When errors occur, the next mirror in the queue is tried.
For instance, if a mirror is provided for the origin , and a file in is going to be fetched, the mirror will be considered for being used, and the URL will be used if the mirror is chosen. Notice that strings are compared and replaced without any pre-processing, so that it's possible to use different schemes (ftp, http, etc) in mirror entries, and even URLs ending in prefixes of directory entries.
Smart has a fast parallel downloading mechanism, allowing multiple connections to be used for one or more sites. The mechanism supports:
and more.
At that moment, the following schemes are nativelly supported:
Additionally, the following schemes are supported when pycurl is available:
Smart Package Manager implements builtin support for removable media (CDROMs, DVDs, etc) in most of the supported channel types. The following features are currently implemented:
Smart has multiple native and completely integrated interfaces:
Besides these interfaces, ksmarttray is also included in the Smart package. It notifies users about available updates using a KDE tray icon.

This command will update the known information about the
given channels. If no channels are given, all channels
which are not disabled or setup for manual updates will
be updated.
Options:
-h, --help Show this help message and exit
--after=MIN Only update if the last successful update happened before the
given delay
Examples:
smart update
smart update mychannel
smart update mychannel1 mychannel2
As you can see, you can control when smart updates, and specify what channels.
Usage: smart install [options] package ...
This command will install one or more packages in the
system. If a new version of an already installed package
is available, the new version will be selected for installation.

Examples:
smart install pkgname
smart install '*kgna*'
smart install pkgname-1.0
smart install pkgname-1.0-1
smart install pkgname1 pkgname2
smart install ./somepackage.file
smart install
Smart install --stepped is a option that will confirm each step. Say you wanted to install foobar and it required some dependencies; before installing/upgrading those dependencies, it ask for confirmation with each package.
Smart install --explain can be a useful option for figuring out why smart wants to downgrade, remove, upgrade or consider certain packages. Basically, it's good for explaining the dependencies and its decisions.
Usage: smart upgrade [options] [package] ...
This command will upgrade one or more packages which
are currently installed in the system. If no packages

Usage: smart channel [options]
This command allows one to manipulate channels. Channels are
used as sources of information about installed and available
packages. Depending on the channel type, a different backend
is used to handle interactions with the operating system and
extraction of information from the given channel.
The following channel types are available:
apt-deb - APT-DEB Repository
apt-rpm - APT-RPM Repository
deb-dir - DEB Directory
deb-sys - DPKG Installed Packages
mirrors - Mirror Information
red-carpet - Red Carpet Channel
rpm-dir - RPM Directory
rpm-hdl - RPM Header List
rpm-md - RPM MetaData
rpm-sys - RPM Installed Packages
slack-site - Slackware Repository
slack-sys - Slackware Installed Packages
up2date-mirrors - Mirror Information (up2date format)
urpmi - URPMI Repository
yast2 - YaST2 Repository
Use --help-typefor more information.
Options:
-h, --help Show this help message and exit
--add Argument is an alias and one or more key=value pairs
defining a channel, or a filename/url pointing to a channel
description in the same format used by --show, or a
directory path where autodetection will be tried
--set Argument is an alias, and one or more key=value pairs
modifying a channel
--remove Arguments are channel aliases to be removed
--remove-all Remove all existent channels
--show Show channels with given aliases, or all channels if no
arguments were given
--edit Edit channels in editor set by $editor
--enable Enable channels with given aliases
--disable Disable channels with given aliases
-y, --yes Execute without asking
--help-type=TYPE Show further information about given type
Examples:
smart channel --help-type apt-rpm
smart channel --add mydb type=rpm-sys name="RPM Database"
smart channel --add mychannel type=apt-rpm name="Some repository" \
baseurl= components=extra
smart channel --set mychannel priority=-100
smart channel --disable mychannel
smart channel --remove mychannel
smart channel --show
smart channel --show mychannel > mychannel.txt
smart channel --add ./mychannel.txt
smart channel --add
smart channel --add /mnt/cdrom
Usage: smart priority [options]
This command allows changing the priority of given packages.
Packages with higher priorities are considered a better option
even when package versions state otherwise. Using priorities
one may avoid unwanted upgrades, force downgrades, select
packages in given channels as preferential, and other kinds
of interesting setups. When a package has no explicit priority,
the channel priority is used. The channel priority may be
changed using the 'channel' command, and defaults to 0 when
not set.
Notice that negatives priorities must be preceded by '--' in
the command line, otherwise they'll be interpreted as command
line options.
Options:
-h, --help Show this help message and exit
--set Set priority
--remove Unset priority
--show Show priorities
--force Ignore problems
Examples:
smart priority --set pkgname 100
smart priority --set pkgname mychannel -- -200
smart priority --remove pkgname
smart priority --remove pkgname mychannel
smart priority --show
smart priority --show pkgname
Usage: smart mirror [options]
This command allows one to manipulate mirrors. Mirrors are URLs
that supposedly provide the same contents as are available in
other URLs, also called origins in this help text. There is no internal
restriction on the kind of information which is mirrored. Once
an origin URL is provided, and one or more mirror URLs are
provided, these mirrors will be considered for any file which
is going to be fetched from an URL starting with the origin URL.
Whether the mirror will be chosen or not will depend on the
history of downloads from this mirror and from other mirrors for
the same URL, since mirrors are automatically balanced so that
the fastest mirror and with less errors is chosen. When errors
occur, the next mirror is tried.
For instance, if a mirror "" is provided
for the origin "ftp://origin.url/other/path/", and a file in
"ftp://origin.url/other/path/subpath/somefile" is going to be
fetched, the mirror will be considered for being used, and the
URL "subpath/somefile" will be used if
the mirror is chosen. Notice that strings are compared and
replaced without any pre-processing, so that it's possible to
use URLs ending in prefixes of directory entries.
Options:
-h, --help Show this help message and exit
--show Show current mirrors
--add Add to the given origin url the given mirror url, provided
either in pairs, or in a given file/url in the format used
by --show
--remove Remove from the given origin url the given mirror url,
provided either in pairs, or in a given file/url in the
format used by --show
--remove-all Remove all mirrors for the given origin urls
--sync=FILE Synchronize mirrors from the given file/url, so that
origins in the given file will have exactly the specified
mirrors
--edit Edit mirrors in editor set by $editor
--clear-history Clear history for the given origins/mirrors, or for all
mirrors
--show-penalities Show current penalities for origins/mirrors, based on the
history information
Examples:
smart mirror --show
smart mirror --add ftp://origin.url/some/path/
smart mirror --remove ftp://origin.url/some/path/
smart mirror --add
smart mirror --sync
smart mirror --clear-history ftp://origin.url/some/path/
smart mirror --clear-history ftp://mirror.url/path/
smart mirror --clear-history
Smart automatically detects and uses the best mirror. Whichever mirror is better, smart will use. It also allows you to continue to download a package if one mirror fails, since smart will automatically switch over to a working mirror.
Usage: smart flag [options]
This command allows one to set, remove, and show package flags.
Package flags are used to tune the behavior of some algorithms
when dealing with the given packages.
Currently known flags are:
lock - Flagged packages will not be removed, if they
are currently installed, nor installed, if they
are currently available.
new - Flagged packages were considered new packages
in the repository when the last update was done.
This flag is automatically manipulated by the
system.
multi-version - Flagged packages may have more than one version
installed in the system at the same time
(backend dependent).
Options:
-h, --help Show this help message and exit
--set Set flags given in pairs of flag name/target, where targets may
use just the package name, or the package name, relation, and
version, such as: lock 'python > 1.0'
--remove Remove flags given in pairs of flag name/target, where targets
may use just the package name, or the package name, relation, and
version, such as: lock 'python > 1.0'
--show Show packages with the flags given as arguments or all flags if
no argument was given
--force Ignore problems
Examples:
smart flag --show
smart flag --show new
smart flag --set lock pkgname
smart flag --remove lock pkgname
smart flag --set lock 'pkgname >= 1.0'
smart flag --remove lock 'pkgname >= 1.0'
Channels are the dictories on the server of repositories that your distribution uses. There are a few ways in which to add channels. The command line way is covered in the above section [ Smart Channel].
Mirrors are different sites or servers that carry the exact same information as the original site. Mirrors can be benificial for obtaining faster download speeds. Not to mention when one server goes down, you have another as a back up. By utilizing mirrors in smart, you give smart the ability to choose which server is best, and to automatically switch when one goes down or performs poorly. The more mirrors you add, the greater the chance of optimizing smart's download capacity.
smart mirror --add
Example: smart mirror --add
smart mirror --add
smart mirror --add
Proxies require authentication to access a server. To set up smart to access a proxy you must make sure pyhton-curl (pycurl) is installed. Then you must set the option in smart's configuration.
smart config --set ftp-proxy=
smart config --set http-proxy=
With smart priorities you can control the prioritization, or ranking, of a channel or package. Priorities are ranked from -200 being the highest priority to 100 being the lowest. A priority with a negative value must be preceeded by a double negative (--). You may want to set priorities to keep packages from being downgraded, or to have desired packages upgraded more readily. The same is true of channels. You may wants a particular channel to be upgraded more readily than the others.
Example 1: smart priority --set packgename 100
Example 2: smart priority --set channelname 100
Example 3: smart priority --set packgename channelname 100
To remove priorities, just use --remove instead of --set.
Flags are a way in which to fine tune smart's algorithm. Flags have three options: lock, new, and multi-version. With lock, it locks the package, so that no changes will be made to that package. With a package that is locked, it will not upgrade or remove that package. New is the system default. Multi-version is when you have more than one version installed in the system at the same time.
Example 1: smart flag --set lock packgename
Example 2: smart flag --set multi-version packagename
To remove a flag, just use --remove instead of --set.
Smart Package Manager has builtin support for removable media (CDROMs, DVDs, etc) in most of the supported channel types. Smart currently offers the following features regarding removable media:
Local removable media are CDROMs, DVDs, etc. In most Linux distributions you will typically find your removable media under /mnt. In SUSE, however, it's under /media. Directories that contain media (/mnt or /media) are actually links that come from /dev and must be registered in /etc/fstab or [ sysfs], and then sysfs must be in /etc/fstab. Please check your distributions documentation for specific information.
With smart, you can have more than one type of media. You can have local removable media (CD-ROM/DVD-ROM) and ftp/http source, as well as local media (some directory on your hard drive), or any of the other types of media covered in this howto.
Remote removable media, is media such as DVD-ROM's or CD-ROM's that are on some url (example: some.host.com). Smart see's this primarily as a URL, but recognizes that it is removable and will ask to change the media when required.
Example:
smart install
smart upgrade
aptosmart is a script that converts, or imports, your apt sources.list to smart channels. aptosmart can be found here] This is an executable script. Download this, and make sure you either delete the channels in /etc/smart/channels or rename the channels. Then
chmod a+x aptosmart.sh
Then as root, run the script like this;
./aptosmart.sh /etc/smart/channels
The aptosmart options are as follows
aptosmart.sh [ - v ] [ - f ] [ - s SOURCE cunning ] listing
Listing: A goal for the Channelfiles
Optionally:
v verbose, f overwrite channelfiles s selects another SOURCE than /etc/apt/sources.list
