NAME

     germinate-pkg-diff --- compare seeds against currently installed packages

SYNOPSIS

     germinate-pkg-diff [-l file] [-m {i|r|d}] [-a arch] [seeds]

DESCRIPTION

     germinate-pkg-diff compares the expansion of a list of seed packages
     against the set of packages installed on the current system.  When
     constructing seeds for a software distribution, it can be used to
     iteratively find packages installed on developers' systems that should be
     included in the seeds.

     A list of seeds against which to compare may be supplied as non-option
     arguments.  Seeds from which they inherit will be added automatically.
     The default is 'desktop'.

OPTIONS

     -l, --list file
       Read the list of currently installed packages from file.  The
       default is to read the output of dpkg --get-selections, and any
       supplied file should be in the same format.

     -m, --mode {i|r|d}
       Set the output mode as follows:

       i     Show the dpkg selections needed to install just these seeds.
             List unseeded but installed files as "deinstall", and seeded
             but uninstalled files as "install".

       r     List unseeded but installed files as "install", and seeded
             but uninstalled files as "deinstall".

       d     Show the differences between the packages specified by the
             seeds and the list of installed packages, in a somewhat
             diff-like format.

     -S, --seed-source source,...
       Fetch seeds from the specified sources.  The default is
       http://people.canonical.com/~ubuntu-archive/seeds/.

     -s, --seed-dist dist
       Fetch seeds for distribution dist.  The default is ubuntu.xenial.

     -d, --dist dist,...
       Operate on the specified distributions.  The default is xenial.
       Listing multiple distributions may be useful, for example, when
       examining both a released distribution and its security updates.

     -a, --arch arch
       Operate on architecture arch.  The default is i386.

BUGS

     --mode r is useless as dpkg --set-selections input.
