     rake — Ruby Make

     Rake is a simple ruby(1) build program with capabilities similar to the regular make(1)

     Rake has the following features:

     ·   Rakefiles (Rake's version of Makefiles) are completely defined in standard Ruby syntax.
         No XML files to edit. No quirky Makefile syntax to worry about (is that a tab or a

     ·   Users can specify tasks with prerequisites.

     ·   Rake supports rule patterns to synthesize implicit tasks.

     ·   Flexible FileLists that act like arrays but know about manipulating file names and

     ·   A library of prepackaged tasks to make building rakefiles easier.


     --version           Display the program version.

                         Put Task and FileTask in the top level namespace

     -D [PATTERN]
     --describe [PATTERN]
                         Describe the tasks (matching optional PATTERN), then exit.

     -E CODE
     --execute-continue CODE
                         Execute some Ruby code, then continue with normal task processing.

     --nosystem          Use standard project Rakefile search paths, ignore system wide

     -I LIBDIR
     --libdir LIBDIR     Include LIBDIR in the search path for required modules.

     --nosearch          Do not search parent directories for the Rakefile.

     --prereqs           Display the tasks and dependencies, then exit.

     --rakelib RAKELIBDIR
     --rakelibdir RAKELIBDIR
                         Auto-import any .rake files in RAKELIBDIR.  (default is rakelib )

     -T [PATTERN]
     --tasks [PATTERN]   Display the tasks (matching optional PATTERN) with descriptions, then

     -e CODE
     --execute CODE      Execute some Ruby code and exit.

     -f FILE
     --rakefile FILE     Use FILE as the rakefile.

     --help              Prints a summary of options.

     --system            Using system wide (global) rakefiles (usually ~/.rake/*.rake ).

     --dry-run           Do a dry run without executing actions.

     -p CODE
     --execute-print CODE
                         Execute some Ruby code, print the result, then exit.

     --quiet             Do not log messages to standard output.

     -r MODULE
     --require MODULE    Require MODULE before executing rakefile.

     --silent            Like --quiet, but also suppresses the 'in directory' announcement.

     --trace             Turn on invoke/execute tracing, enable full backtrace.

     --verbose           Log message to standard output (default).

     --rules             Trace the rules resolution.
