Description:

def remove(name=None, pkgs=None, saltenv='base', **kwargs):
    '''
    Remove packages with pkgrm

    name
        The name of the package to be deleted

    By default salt automatically provides an adminfile, to automate package
    removal, with these options set::

        email=
        instance=quit
        partial=nocheck
        runlevel=nocheck
        idepend=nocheck
        rdepend=nocheck
        space=nocheck
        setuid=nocheck
        conflict=nocheck
        action=nocheck
        basedir=default

    You can override any of these options in two ways. First you can optionally
    pass any of the options as a kwarg to the module/state to override the
    default value or you can optionally pass the 'admin_source' option
    providing your own adminfile to the minions.

    Note: You can find all of the possible options to provide to the adminfile
    by reading the admin man page:

    .. code-block:: bash

        man -s 4 admin


    Multiple Package Options:

    pkgs
        A list of packages to delete. Must be passed as a python list. The
        ``name`` parameter will be ignored if this option is passed.

    .. versionadded:: 0.16.0


    Returns a dict containing the changes.

    CLI Example:

    .. code-block:: bash

        salt '*' pkg.remove <package name>
        salt '*' pkg.remove SUNWgit
        salt '*' pkg.remove <package1>,<package2>,<package3>
        salt '*' pkg.remove pkgs='["foo", "bar"]'
