-- TRACING

-- | Write an action to the trace list, along with the start/end time of running the IO action.
--   The 'Development.Shake.cmd' and 'Development.Shake.command' functions automatically call 'traced'
--   with the name of the executable. The trace list is used for profile reports (see 'shakeReport').
--
--   By default 'traced' prints some useful extra context about what
--   Shake is building, e.g.:
--
-- > # traced message (for myobject.o)
--
--   To suppress the output of 'traced' (for example you want more control
--   over the message using 'putInfo'), use the 'quietly' combinator.
--
--   It is recommended that the string passed to 'traced' is short and that only a small number of unique strings
--   are used (makes profiling work better).
--   The string does not need to make sense on its own, only in conjunction with the target it is building.

-- | Batch different outputs into a single 'Action', typically useful when a command has a high
--   startup cost - e.g. @apt-get install foo bar baz@ is a lot cheaper than three separate
--   calls to @apt-get install@. As an example, if we have a standard build rule:
--
-- @
-- \"*.out\" 'Development.Shake.%>' \\out -> do
--     'Development.Shake.need' [out '-<.>' \"in\"]
--     'Development.Shake.cmd' "build-multiple" [out '-<.>' \"in\"]
-- @
--
--   Assuming that @build-multiple@ can compile multiple files in a single run,
--   and that the cost of doing so is a lot less than running each individually,
--   we can write:
--
-- @
-- 'batch' 3 (\"*.out\" 'Development.Shake.%>')
--     (\\out -> do 'Development.Shake.need' [out '-<.>' \"in\"]; pure out)
--     (\\outs -> 'Development.Shake.cmd' "build-multiple" [out '-<.>' \"in\" | out \<- outs])
-- @
--
--   In constrast to the normal call, we have specified a maximum batch size of 3,
--   an action to run on each output individually (typically all the 'need' dependencies),
--   and an action that runs on multiple files at once. If we were to require lots of
--   @*.out@ files, they would typically be built in batches of 3.
--
--   If Shake ever has nothing else to do it will run batches before they are at the maximum,
--   so you may see much smaller batches, especially at high parallelism settings.
