=head1 NAME

aptitude-robot - automate package choice management

=head1 SYNOPSIS

aptitude-robot [options]

aptitude-robot --help

=head1 DESCRIPTION

aptitude-robot uses configuration files to install and remove Debian software
packages automatically.  This allows hands-off setup and maintenance of
workstations and servers.  Create package lists in a development environment
and copy the package lists over to the production machines.  aptitude-robot
will then make sure that the packages mentioned in the lists are installed or
removed as indicated.

=head1 OPTIONS

=over 4

=item B<--force-install>

give priority to install(+), remove(-), and purge(_) actions over keep(:) and hold(=)

=item B<--config-dir F</path/to/config/dir>>

specify an alternate configuration directory.  Defaults to F</etc/aptitude-robot>

=item B<--show-cmdline>

only show the command that would be executed

=item B<--help>

Prints this page.

=item I<other options>

any option not recognized by aptitude-robot itself is passed through to
aptitude.  The options B<-q> and B<-s> are likely to be used occasionally.  See
L<aptitude(8)> for details.

=back

=head1 CONFIGURATION

The configuration directory given by the C<--config-dir> (or
F</etc/aptitude-robot> by default) must contain a directory named F<pkglist.d>.
This directory may have several package list files that are chosen according to
the criteria of L<run-parts(8)>.  They are concatenated in the order given by
L<run-parts(8)>.

Each line shall contain an action and a package name separated by white space.
The actions are those used by the C<aptitude> command line interface (see
aptitude documentation).  Typically they are:

I<+  package  # install package>

I<+M package  # install package and mark it as automatically installed>

I<-  package  # remove package>

I<_  package  # purge package>

I<:  package  # keep package at current version>

I<=  package  # mark a package as "hold", i.e., prevent automatic updates>

If a package is mentioned several times the last entry will determine the
action.  If the C<--force-install> option is given the keep(:) and hold(=)
actions are given lower priority, i.e., the appear only when no other action
for the package is specified.

A C<#> character starts a comment extending to the end of line.  Empty lines or
extra white space at the beginning or end of line is ignored.

Optionally the configuration directory may contain a file name F<options>
containing extra options given to aptitude in the form of one option per line.

Optionally the configuration directory may contain two directories
F<triggers.pre> and F<triggers.post> with scripts that are executed by
L<run-parts(8)> before and after aptitude respectively.
