# C-INTERCAL uses minor-major ordering of version components and
# negative version numbers. We map any negative version component M
# to _pre<M+10000>, and any subsequent nonnegative component N to _p<N>.
# For example, upstream version 0.33 is mapped to Gentoo version 33.0
# and 0.-2.0.29 is mapped to 29.0_pre9998_p0.

# pre) offset=-10000 ;;
# *) j="$((i+offset)).${j}"
