-- Tests for command line parsing
-- ------------------------------
--
-- The initial line specifies the command line, in the format
--
-- # cmd: mypy <options>
--
-- Note that # flags: --some-flag IS NOT SUPPORTED.
-- Use # cmd: mypy --some-flag ...
--
-- '== Return code: <value>' is added to the output when the process return code
-- is "nonobvious" -- that is, when it is something other than 0 if there are no
-- messages and 1 if there are.
-- Directories/packages on the command line
-- ----------------------------------------
