# @sample etc/somefile.conf.sample
#
# This will install the somefile.conf.sample and automatically copy to
# somefile.conf if it doesn't exist. On deinstall it will remove the
# somefile.conf if it still matches the sample, otherwise it is
# kept.
#
# This replaces the old pattern:
#  @unexec if cmp -s %D/etc/pkgtools.conf %D/etc/pkgtools.conf.sample; then rm -f %D/etc/pkgtools.conf; fi
#  etc/pkgtools.conf.sample
#  @exec [ -f %B/pkgtools.conf ] || cp %B/%f %B/pkgtools.conf
