# Top level Makefile to build Zenith and PostgreSQL
#
all: zenith postgres

# We don't want to run 'cargo build' in parallel with the postgres build,
# because interleaving cargo build output with postgres build output looks
# confusing. Also, 'cargo build' is parallel on its own, so it would be too
# much parallelism. (Recursive invocation of postgres target still gets any
# '-j' flag from the command line, so 'make -j' is still useful.)
