RakeFileUtils provides a custom version of the FileUtils methods that respond to the verbose and nowrite commands.

Public Instance methods
nowrite(value=nil) {|| ...}

Get/set the nowrite flag controlling output from the FileUtils utilities. If verbose is true, then the utility method is echoed to standard output.

Examples: 

   nowrite              # return the current value of the nowrite flag
   nowrite(v)           # set the nowrite flag to _v_.
   nowrite(v) { code }  # Execute code with the nowrite flag set temporarily to _v_.
                        # Return to the original value when code is done.

verbose(value=nil) {|| ...}

Get/set the verbose flag controlling output from the FileUtils utilities. If verbose is true, then the utility method is echoed to standard output.

Examples: 

   verbose              # return the current value of the verbose flag
   verbose(v)           # set the verbose flag to _v_.
   verbose(v) { code }  # Execute code with the verbose flag set temporarily to _v_.
                        # Return to the original value when code is done.

when_writing(msg=nil) {|| ...}

Use this function to prevent protentially destructive ruby code from running when the :nowrite flag is set.

Example: 

  when_writing("Building Project") do
    project.build
  end

The following code will build the project under normal conditions. If the nowrite(true) flag is set, then the example will print: 

     DRYRUN: Building Project

instead of actually building the project.
