# crystal-X-OpenBSDX.X.tar.gz is an archive of a bootstrap compiler object
# (crystal.o) which can be cross-compiled on another platform by installing the
# current version of Crystal there, then checking out the source for that
# version, applying patches included in this port, and running:
#
# 	make crystal FLAGS="--cross-compile --target amd64-unknown-openbsd7.1"
#
# The result will be built at .build/crystal.o
