# @BLURB: An Interface for installing contributed bash-completion scripts
# @DESCRIPTION:
# Simple eclass that provides an interface for installing
# contributed (ie not included in bash-completion proper)
# bash-completion scripts.
# @ECLASS-VARIABLE: BASHCOMPLETION_NAME
# @DESCRIPTION:
# Install the completion script with this name (see also dobashcompletion)
# @ECLASS-VARIABLE: BASHCOMPFILES
# @DESCRIPTION:
# Space delimited list of files to install if dobashcompletion is called without
# arguments.
EXPORT_FUNCTIONS pkg_postinst
IUSE="bash-completion"
# Allow eclass to be inherited by eselect without a circular dependency
if [[ ${CATEGORY}/${PN} != app-admin/eselect ]]; then

# @FUNCTION: dobashcompletion
# @USAGE: [file] [new_file]
# @DESCRIPTION:
# The first argument is the location of the bash-completion script to install,
# and is required if BASHCOMPFILES is not set. The second argument is the name
# the script will be installed as. If BASHCOMPLETION_NAME is set, it overrides
# the second argument. If no second argument is given and BASHCOMPLETION_NAME
# is not set, it will default to ${PN}.
