Use system2() not system()

That means workflow(..., command = "make --jobs=2") becomes worflow(..., command = "make", args = "--jobs=2").

Makefiles are no longer standalone!

You must call workflow(...) to run the Makefile. Do not use the command line. The reason is that workflow(...) creates dummy timestamp files so that the Makefile can see which jobs don't need to be run. As a consequence, workflow(...) needs to run an initialization step right before each time the Makefile is called. Otherwise, your build steps will be incorrect. You can just generate the Makefile without running it using workflow(..., run = FALSE).

Add functions commands_string() and commands_batch()

Functions commands_string() and commands_batch() are useful counterparts to commands(). See the vignette for a demo.

Fix issues #3 and #5.

The package is now stricter about the names of targets. The names of phony targets may no longer conflict with the names of real targets under any circumstance.

Fix name ordering and point to vignette in help files.

Use help_remakeGenerator().
