# for now this is kind of ad-hoc:
#
# 1. The default flow command is check with the --all flag. This flag
# can be overriden here with the line "all: false". Anything besides
# "false" is ignored, and the setting itself is ignored if a command
# besides check is run.
#
# 2. The default flow command can be overriden here by supplying the
# entire command on a line that begins with "cmd:". (Note: for writing
# incremental tests, use the option below). A line beginning with
# "stdin:" can additionally supply arguments to pass to the command via
# standard input. We start the server before running the command and
# stop the server after we get a result.
#
# 3. Integration tests that interleave flow commands with file system
# commands (for testing incremental checks, e.g.) are written by
# supplying the name of a shell script on a line that begins with
# "shell:". The shell script is passed the location of the flow binary
# as argument ($1). We start the server before running the script and
# stop the server after the script exits.
