#compdef rpm

# This uses `_arguments' in a state-machine kind of way. These states
# have names and before executing the default action for such a state
# we try to call a function with the name `_rpm_<state>'. If such a
# function exists, we return with its return status immediately. This
# allows users to override the default completions by simply defining
# these functions.
# The states (and possible values for the `<state>' above) are:
#
#  query
#    complete for `rpm -q' query
#  verify
#    complete for `rpm --verify'
#  install
#    complete for `rpm -i' or `rpm --install'
#  upgrade
#    complete for `rpm -U' or `rpm --upgrade'
#  uninstall
#    complete for `rpm -e' or `rpm --erase'
#  build_b
#    complete for `rpm -bx' (the stage `x' is already completed)
#  build_t
#    complete for `rpm -tx' (the stage `x' is already completed)
#  sigcheck
#    complete for `rpm --sigcheck'
#  rebuild
#    complete for `rpm --rebuild'
#  package
#    complete a RPM package name
#  package_file
#    complete a RPM package file name
#  package_or_file
#    the previous two together
#  tags
#    complete a tag name
#  capability
#    complete a capability
#  relocate
#    complete a `old=new' pair of paths
