# @BLURB: Testing implementation of EAPI 9 ver_replacing
# @DESCRIPTION:
# A stand-alone implementation of the ver_replacing function aimed
# for EAPI 9. Intended to be used for wider testing of the proposed
# function and to allow ebuilds to switch to the new model early, with
# minimal change needed for the actual EAPI 9.
#
# @CODE
# if ver_replacing -lt 1.2; then
# elog "The frobnicate command was dropped in version 1.2"
# fi

# @FUNCTION: ver_replacing
# @USAGE: <op> <ver>
# @RETURN: 0 if any element of REPLACING_VERSIONS qualifies, 1 otherwise
# @DESCRIPTION:
# Compare each element <v> of REPLACING_VERSIONS with version <ver>
# using ver_test(). Return 0 (true) if any element <v> fulfills
# "ver_test <v> <op> <ver>", 1 (false) otherwise.
#
# Note: If REPLACING_VERSIONS is empty, 1 (false) is returned.
