Helper function to set options for verbosity.
remake_verbose(verbose = getOption("remake.verbose", TRUE), noop = getOption("remake.verbose.noop", TRUE), command = getOption("remake.verbose.command", TRUE), command_abbreviate = getOption("remake.verbose.command.abbreviate", TRUE), target = NULL)
FALSE is useful for very large projects.FALSE then the command will
be allowed to run on for as many lines as required.message, cat or print). If FALSE then
these messages will be suppressed.The first four options have a natural nesting: setting
progress=FALSE prevents printing any progress information,
so the value of noop, command and
command_abbreviate does not matter. Similarly, setting
command=FALSE means that command_abbreviate does not
matter.
