# TODO: 
# - In posttrans we could get the changelogs from rpmdb thus avoiding
#   the costly 'otherdata' import but it would be nice to be able to present
#   the changelogs (optionally) *before* the y/n prompt and for that the import
#   would be needed anyway.
# - Add support to mail the changelogs to given address
# - Add cli-option for turning this on/off
