-= RAKE -- Ruby Make
-
-This package contains Rake, a simple ruby build program with capabilities
-similar to make.
-
-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 space?)
-
-* 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 paths.
-
-* A library of prepackaged tasks to make building rakefiles easier. For example,
-  tasks for building tarballs and publishing to FTP or SSH sites.  (Formerly
-  tasks for building RDoc and Gems were included in rake but they're now
-  available in RDoc and RubyGems respectively.)
-
-* Supports parallel execution of tasks.
-
-== Installation
-
-=== Gem Installation
-
-Download and install rake with the following.
-
-   gem install rake
-
-== Usage
-
-=== Simple Example
-
-First, you must write a "Rakefile" file which contains the build rules. Here's
-a simple example:
-
-  task :default => [:test]
-
-  task :test do
-    ruby "test/unittest.rb"

-
-This Rakefile has two tasks:
-
-* A task named "test", which - upon invocation - will run a unit test file in
-  Ruby.
-* A task named "default". This task does nothing by itself, but it has exactly
-  one dependency, namely the "test" task. Invoking the "default" task will
-  cause Rake to invoke the "test" task as well.
-
-Running the "rake" command without any options will cause it to run the
-"default" task in the Rakefile:
-
-  % ls
-  Rakefile     test/
-  % rake
-  (in /home/some_user/Projects/rake)
-  ruby test/unittest.rb
-  ....unit test output here...
-
-Type "rake --help" for all available options.

-= Rake Command Line Usage
-
-Rake is invoked from the command line using:
-
-    % rake [options ...]  [VAR=VALUE ...]  [targets ...]
-
-Options are:
-
-[<tt><em>name</em>=<em>value</em></tt>]
-    Set the environment variable <em>name</em> to <em>value</em>
-    during the execution of the <b>rake</b> command.  You can access
-    the value by using ENV['<em>name</em>'].
-
-[<tt>--all</tt> (-A)]
-    Used in combination with the -T and -D options, will force
-    those options to show all the tasks, even the ones without comments.
-
-[<tt>--backtrace</tt>{=_output_} (-n)]
-    Enable a full backtrace (i.e. like --trace, but without the task
-    tracing details). The _output_ parameter is optional, but if
-    specified it controls where the backtrace output is sent. If
-    _output_ is <tt>stdout</tt>, then backtrace output is directed to
-    stardard output. If _output_ is <tt>stderr</tt>, or if it is
-    missing, then the backtrace output is sent to standard error.
-
-[<tt>--comments</tt>]
-    Used in combination with the -W options to force the output to
-    contain commented options only. This is the reverse of
-    <tt>--all</tt>.
-
-[<tt>--describe</tt> _pattern_ (-D)]
-    Describe the tasks (matching optional PATTERN), then exit.
-
-[<tt>--dry-run</tt> (-n)]
-    Do a dry run.  Print the tasks invoked and executed, but do not
-    actually execute any of the actions.
-
-[<tt>--execute</tt> _code_ (-e)]
-    Execute some Ruby code and exit.
-
-[<tt>--execute-print</tt> _code_ (-p)]
-    Execute some Ruby code, print the result, and exit.
-
-[<tt>--execute-continue</tt> _code_ (-E)]
-    Execute some Ruby code, then continue with normal task processing.
-
-[<tt>--help</tt>  (-H)]
-    Display some help text and exit.
-
-[<tt>--jobs</tt> _number_  (-j)]
-    Specifies the number of active concurrent tasks used. The
-    suggested value is equal to the number of CPUs. The concurrent
-    tasks are used to execute the <tt>multitask</tt> prerequisites.
-    Also see the <tt>-m</tt> option which turns all tasks into
-    multitasks.
-
-    Sample values:
-     (no -j) : unlimited concurrent tasks (standard rake behavior)
-     -j      : 2 concurrent tasks (exact number may change)
-     -j 16   : 16 concurrent tasks
-
-[<tt>--job-stats</tt> _level_]
-
-    Display job statistics at the completion of the run. By default,
-    this will display the requested number of active tasks (from the
-    -j options) and the maximum number of tasks in play at any given
-    time.
-
-    If the optional _level_ is <tt>history</tt>, then a complete trace
-    of task history will be displayed on standard output.
-
-[<tt>--libdir</tt> _directory_  (-I)]
-    Add _directory_ to the list of directories searched for require.
-
-[<tt>--multitask</tt> (-m)]
-    Treat all tasks as multitasks. ('make/drake' semantics)
-
-[<tt>--nosearch</tt>  (-N)]
-    Do not search for a Rakefile in parent directories.
-
-[<tt>--prereqs</tt>  (-P)]
-    Display a list of all tasks and their immediate prerequisites.
-
-[<tt>--quiet</tt> (-q)]
-    Do not echo commands from FileUtils.
-
-[<tt>--rakefile</tt> _filename_ (-f)]
-    Use _filename_ as the name of the rakefile. The default rakefile
-    names are +rakefile+ and +Rakefile+ (with +rakefile+ taking
-    precedence). If the rakefile is not found in the current
-    directory, +rake+ will search parent directories for a match. The
-    directory where the Rakefile is found will become the current
-    directory for the actions executed in the Rakefile.
-
-[<tt>--rakelibdir</tt> _rakelibdir_ (-R)]
-    Auto-import any .rake files in RAKELIBDIR. (default is 'rakelib')
-
-[<tt>--require</tt> _name_ (-r)]
-    Require _name_ before executing the Rakefile.
-
-[<tt>--rules</tt>]
-    Trace the rules resolution.
-
-[<tt>--silent (-s)</tt>]
-    Like --quiet, but also suppresses the 'in directory' announcement.
-
-[<tt>--suppress-backtrace _pattern_ </tt>]
-    Line matching the regular expression _pattern_ will be removed
-    from the backtrace output. Note that the --backtrace option is the
-    full backtrace without these lines suppressed.
-
-[<tt>--system</tt> (-g)]
-    Use the system wide (global) rakefiles. The project Rakefile is
-    ignored. By default, the system wide rakefiles are used only if no
-    project Rakefile is found. On Unix-like system, the system wide
-    rake files are located in $HOME/.rake. On a windows system they
-    are stored in $APPDATA/Rake.
-
-[<tt>--no-system</tt> (-G)]
-    Use the project level Rakefile, ignoring the system-wide (global)
-    rakefiles.
-
-[<tt>--tasks</tt> <em>pattern</em> (-T)]
-    Display a list of the major tasks and their comments.  Comments
-    are defined using the "desc" command.  If a pattern is given, then
-    only tasks matching the pattern are displayed.
-
-[<tt>--trace</tt>{=_output_} (-t)]
-    Turn on invoke/execute tracing. Also enable full backtrace on
-    errors. The _output_ parameter is optional, but if specified it
-    controls where the trace output is sent. If _output_ is
-    <tt>stdout</tt>, then trace output is directed to stardard output.
-    If _output_ is <tt>stderr</tt>, or if it is missing, then trace
-    output is sent to standard error.
-
-[<tt>--verbose</tt> (-v)]
-    Echo the Sys commands to standard output.
-
-[<tt>--version</tt> (-V)]
-    Display the program version and exit.
-
-[<tt>--where</tt> <em>pattern</em> (-W)]
-    Display tasks that match <em>pattern</em> and the file and line
-    number where the task is defined. By default this option will
-    display all tasks, not just the tasks that have descriptions.
-
-[<tt>--no-deprecation-warnings</tt> (-W)]
-    Do not display the deprecation warnings.
-
-In addition, any command line option of the form
-<em>VAR</em>=<em>VALUE</em> will be added to the environment hash
-<tt>ENV</tt> and may be tested in the Rakefile.

-[<b>action</b>]
-	Code to be executed in order to perform a task.  Actions in a
-	rakefile are specified in a code block (usually delimited by
-	+do+/+end+ pairs.
-
-[<b>execute</b>]
-	When a task is executed, all of its actions are performed, in

-	<tt>invoke</tt>, <tt>execute</tt> always executes the actions
-	(without invoking or executing the prerequisites).
-
-[<b>file task</b> (FileTask)]
-	 A file task is a task whose purpose is to create a file
-	 (which has the same name as the task).  When invoked, a file
-	 task will only execute if one or more of the following
-	 conditions are true.
-
-         1. The associated file does not exist.
-	 2. A prerequisite has a later time stamp than the existing file.
-
-	 Because normal Tasks always have the current time as
-	 timestamp, a FileTask that has a normal Task prerequisite
-	 will always execute.
-
-[<b>invoke</b>]
-	When a task is invoked, first we check to see if it has been
-	invoked before.  if it has been, then nothing else is done.
-	If this is the first time its been invoked, then we invoke
-	each of its prerequisites.  Finally, we check to see if we
-	need to execute the actions of this task by calling
-	<tt>needed?</tt>.  Finally, if the task is needed, we execute
-	its actions.
-
-	NOTE: Currently prerequisites are invoked even if the task is
-	not needed.  This may change in the future.
-
-[<b>prerequisites</b>]
-	Every task has a set (possibly empty) of prerequisites.  A
-	prerequisite P to Task T is itself a task that must be invoked
-	before Task T.
-
-[<b>rule</b>]
-	A rule is a recipe for synthesizing a task when no task is
-	explicitly defined.  Rules generally synthesize file tasks.
-
-[<b>task</b> (Task)]
-	Basic unit of work in a rakefile.  A task has a name, a set of
-	prerequisites and a list of actions to be performed.

-= Rakefile Format (as of version 0.8.7)
-
-First of all, there is no special format for a Rakefile.  A Rakefile
-contains executable Ruby code.  Anything legal in a ruby script is
-allowed in a Rakefile.
-
-Now that we understand there is no special syntax in a Rakefile, there
-are some conventions that are used in a Rakefile that are a little
-unusual in a typical Ruby program.  Since a Rakefile is tailored to
-specifying tasks and actions, the idioms used in a Rakefile are
-designed to support that.
-
-So, what goes into a Rakefile?
-
-== Tasks
-
-Tasks are the main unit of work in a Rakefile.  Tasks have a name
-(usually given as a symbol or a string), a list of prerequisites (more
-symbols or strings) and a list of actions (given as a block).
-
-=== Simple Tasks
-
-A task is declared by using the +task+ method.  +task+ takes a single
-parameter that is the name of the task.
-
-  task :name
-
-=== Tasks with Prerequisites
-
-Any prerequisites are given as a list (enclosed in square brackets)
-following the name and an arrow (=>).
-
-  task :name => [:prereq1, :prereq2]
-
-<b>NOTE:</b> Although this syntax looks a little funky, it is legal
-Ruby.  We are constructing a hash where the key is :name and the value
-for that key is the list of prerequisites.  It is equivalent to the
-following ...
-
-  hash = Hash.new
-  hash[:name] = [:prereq1, :prereq2]
-  task(hash)
-
-=== Tasks with Actions
-
-Actions are defined by passing a block to the +task+ method.  Any Ruby
-code can be placed in the block.  The block may reference the task
-object via the block parameter.
-
-  task :name => [:prereq1, :prereq2] do |t|
-    # actions (may reference t)
-  end
-
-=== Multiple Definitions
-
-A task may be specified more than once.  Each specification adds its
-prerequisites and actions to the existing definition.  This allows one
-part of a rakefile to specify the actions and a different rakefile
-(perhaps separately generated) to specify the dependencies.
-
-For example, the following is equivalent to the single task
-specification given above.
-
-  task :name
-  task :name => [:prereq1]
-  task :name => [:prereq2]
-  task :name do |t|
-    # actions
-  end
-
-== File Tasks
-
-Some tasks are designed to create a file from one or more other files.
-Tasks that generate these files may be skipped if the file already
-exists.  File tasks are used to specify file creation tasks.
-
-File tasks are declared using the +file+ method (instead of the +task+
-method).  In addition, file tasks are usually named with a string
-rather than a symbol.
-
-The following file task creates a executable program (named +prog+)
-given two object files name <tt>a.o</tt> and <tt>b.o</tt>.  The tasks
-for creating <tt>a.o</tt> and <tt>b.o</tt> are not shown.
-
-  file "prog" => ["a.o", "b.o"] do |t|
-    sh "cc -o #{t.name} #{t.prerequisites.join(' ')}"
-  end
-
-== Directory Tasks
-
-It is common to need to create directories upon demand.  The
-+directory+ convenience method is a short-hand for creating a FileTask
-that creates the directory.  For example, the following declaration
-...
-
-  directory "testdata/examples/doc"
-
-is equivalent to ...
-
-  file "testdata"              do |t| mkdir t.name end
-  file "testdata/examples"     do |t| mkdir t.name end
-  file "testdata/examples/doc" do |t| mkdir t.name end
-
-The +directory+ method does not accept prerequisites or actions, but
-both prerequisites and actions can be added later.  For example ...
-
-  directory "testdata"
-  file "testdata" => ["otherdata"]
-  file "testdata" do
-    cp Dir["standard_data/*.data"], "testdata"
-  end
-
-== Tasks with Parallel Prerequisites
-
-Rake allows parallel execution of prerequisites using the following syntax:
-
-  multitask :copy_files => [:copy_src, :copy_doc, :copy_bin] do
-    puts "All Copies Complete"
-  end
-
-In this example, +copy_files+ is a normal rake task.  Its actions are
-executed whenever all of its prerequisites are done.  The big
-difference is that the prerequisites (+copy_src+, +copy_bin+ and
-+copy_doc+) are executed in parallel.  Each of the prerequisites are
-run in their own Ruby thread, possibly allowing faster overall runtime.
-
-=== Secondary Prerequisites
-
-If any of the primary prerequisites of a multitask have common secondary
-prerequisites, all of the primary/parallel prerequisites will wait
-until the common prerequisites have been run.
-
-For example, if the <tt>copy_<em>xxx</em></tt> tasks have the
-following prerequisites:
-
-  task :copy_src => [:prep_for_copy]
-  task :copy_bin => [:prep_for_copy]
-  task :copy_doc => [:prep_for_copy]
-
-Then the +prep_for_copy+ task is run before starting all the copies in
-parallel.  Once +prep_for_copy+ is complete, +copy_src+, +copy_bin+,
-and +copy_doc+ are all run in parallel.  Note that +prep_for_copy+ is
-run only once, even though it is referenced in multiple threads.
-
-=== Thread Safety
-
-The Rake internal data structures are thread-safe with respect
-to the multitask parallel execution, so there is no need for the user
-to do extra synchronization for Rake's benefit.  However, if there are
-user data structures shared between the parallel prerequisites, the
-user must do whatever is necessary to prevent race conditions.
-
-== Tasks with Arguments
-
-Prior to version 0.8.0, rake was only able to handle command line
-arguments of the form NAME=VALUE that were passed into Rake via the
-ENV hash.  Many folks had asked for some kind of simple command line
-arguments, perhaps using "--" to separate regular task names from
-argument values on the command line.  The problem is that there was no
-easy way to associate positional arguments on the command line with
-different tasks.  Suppose both tasks :a and :b expect a command line
-argument: does the first value go with :a?  What if :b is run first?
-Should it then get the first command line argument.
-
-Rake 0.8.0 solves this problem by explicitly passing values directly
-to the tasks that need them.  For example, if I had a release task
-that required a version number, I could say:
-
-   rake release[0.8.2]
-
-And the string "0.8.2" will be passed to the :release task.  Multiple
-arguments can be passed by separating them with a comma, for example:
-
-   rake name[john,doe]
-
-Just a few words of caution.  The rake task name and its arguments
-need to be a single command line argument to rake.  This generally
-means no spaces.  If spaces are needed, then the entire rake +
-argument string should be quoted.  Something like this:
-
-   rake "name[billy bob, smith]"
-
-(Quoting rules vary between operating systems and shells, so make sure
-you consult the proper docs for your OS/shell).
-
-=== Tasks Arguments and the Environment
-
-Task argument values can also be picked up from the environment.  For
-example, if the "release" task expected a parameter named
-"release_version", then either
-
-   rake release[0.8.2]
-
-or
-
-   RELEASE_VERSION=0.8.2 rake release
-
-will work.  Environment variable names must either match the task
-parameter exactly, or match an all-uppercase version of the task
-parameter.
-
-=== Tasks that Expect Parameters
-
-Parameters are only given to tasks that are setup to expect them.  In
-order to handle named parameters, the task declaration syntax for
-tasks has been extended slightly.
-
-For example, a task that needs a first name and last name might be
-declared as:
-
-   task :name, [:first_name, :last_name]
-
-The first argument is still the name of the task (:name in this case).
-The next two arguments are the names of the parameters expected by
-:name in an array (:first_name and :last_name in the example).
-
-To access the values of the parameters, the block defining the task
-behaviour can now accept a second parameter:
-
-   task :name, [:first_name, :last_name] do |t, args|
-     puts "First name is #{args.first_name}"
-     puts "Last  name is #{args.last_name}"
-   end
-
-The first argument of the block "t" is always bound to the current
-task object.  The second argument "args" is an open-struct like object
-that allows access to the task arguments.  Extra command line
-arguments to a task are ignored.  Missing command line arguments are
-picked up from matching environment variables.  If there are no
-matching environment variables, they are given the nil value.
-
-If you wish to specify default values for the arguments, you can use
-the with_defaults method in the task body.  Here is the above example
-where we specify default values for the first and last names:
-
-   task :name, [:first_name, :last_name] do |t, args|
-     args.with_defaults(:first_name => "John", :last_name => "Dough")
-     puts "First name is #{args.first_name}"
-     puts "Last  name is #{args.last_name}"
-   end
-
-=== Tasks that Expect Parameters and Have Prerequisites
-
-Tasks that use parameters have a slightly different format for
-prerequisites.  Use the arrow notation to indicate the prerequisites
-for tasks with arguments.  For example:
-
-   task :name, [:first_name, :last_name] => [:pre_name] do |t, args|
-     args.with_defaults(:first_name => "John", :last_name => "Dough")
-     puts "First name is #{args.first_name}"
-     puts "Last  name is #{args.last_name}"
-   end
-
-=== Deprecated Task Parameters Format
-
-There is an older format for declaring task parameters that omitted
-the task argument array and used the :needs keyword to introduce the
-dependencies.  That format is still supported for compatibility, but
-is not recommended for use.  The older format may be dropped in future
-versions of rake.
-
-== Accessing Task Programmatically
-
-Sometimes it is useful to manipulate tasks programmatically in a
-Rakefile. To find a task object, use the <tt>:[]</tt> operator on the
-<tt>Rake::Task</tt>.
-
-=== Programmatic Task Example
-
-For example, the following Rakefile defines two tasks.  The :doit task
-simply prints a simple "DONE" message.  The :dont class will lookup
-the doit class and remove (clear) all of its prerequisites and
-actions.
-
-   task :doit do
-     puts "DONE"
-   end
-
-   task :dont do
-     Rake::Task[:doit].clear
-   end
-
-Running this example:
-
-  $ rake doit
-  (in /Users/jim/working/git/rake/x)
-  DONE
-  $ rake dont doit
-  (in /Users/jim/working/git/rake/x)
-  $
-
-The ability to programmatically manipulate tasks gives rake very
-powerful meta-programming capabilities w.r.t. task execution, but
-should be used with caution.
-
-== Rules
-
-When a file is named as a prerequisite, but does not have a file task
-defined for it, Rake will attempt to synthesize a task by looking at a
-list of rules supplied in the Rakefile.
-
-Suppose we were trying to invoke task "mycode.o", but no task is
-defined for it.  But the rakefile has a rule that look like this ...
-
-  rule '.o' => ['.c'] do |t|
-    sh "cc #{t.source} -c -o #{t.name}"
-  end
-
-This rule will synthesize any task that ends in ".o".  It has a
-prerequisite a source file with an extension of ".c" must exist.  If
-Rake is able to find a file named "mycode.c", it will automatically
-create a task that builds "mycode.o" from "mycode.c".
-
-If the file "mycode.c" does not exist, rake will attempt
-to recursively synthesize a rule for it.
-
-When a task is synthesized from a rule, the +source+ attribute of the
-task is set to the matching source file.  This allows us to write
-rules with actions that reference the source file.
-
-=== Advanced Rules
-
-Any regular expression may be used as the rule pattern.  Additionally,
-a proc may be used to calculate the name of the source file.  This
-allows for complex patterns and sources.
-
-The following rule is equivalent to the example above.
-
-  rule( /\.o$/ => [
-    proc {|task_name| task_name.sub(/\.[^.]+$/, '.c') }
-  ]) do |t|
-    sh "cc #{t.source} -c -o #{t.name}"
-  end
-
-<b>NOTE:</b> Because of a _quirk_ in Ruby syntax, parenthesis are
-required on *rule* when the first argument is a regular expression.
-
-The following rule might be used for Java files ...
-
-  rule '.class' => [
-    proc { |tn| tn.sub(/\.class$/, '.java').sub(/^classes\//, 'src/') }
-  ] do |t|
-    java_compile(t.source, t.name)
-  end
-
-<b>NOTE:</b> +java_compile+ is a hypothetical method that invokes the
-java compiler.
-
-== Importing Dependencies
-
-Any ruby file (including other rakefiles) can be included with a
-standard Ruby +require+ command.  The rules and declarations in the
-required file are just added to the definitions already accumulated.
-
-Because the files are loaded _before_ the rake targets are evaluated,
-the loaded files must be "ready to go" when the rake command is
-invoked.  This make generated dependency files difficult to use.  By
-the time rake gets around to updating the dependencies file, it is too
-late to load it.
-
-The +Rake.import+ command addresses this by specifying a file to be
-loaded _after_ the main rakefile is loaded, but _before_ any targets
-on the command line are invoked.  In addition, if the file name
-matches an explicit task, that task is invoked before loading the
-file.  This allows dependency files to be generated and used in a
-single rake command invocation.
-
-<b>NOTE:</b> Starting in Rake version 0.9.0, the top level +import+
-command is deprecated and we recommend using the scoped
-"+Rake.import+" command mentioned above.  Future versions of Rake will
-drop support for the top level +import+ command.
-
-=== Example:
-
-  require 'rake/loaders/makefile'
-
-  file ".depends.mf" => [SRC_LIST] do |t|
-    sh "makedepend -f- -- #{CFLAGS} -- #{t.prerequisites} > #{t.name}"
-  end
-
-  Rake.import ".depends.mf"
-
-If ".depends" does not exist, or is out of date w.r.t. the source
-files, a new ".depends" file is generated using +makedepend+ before
-loading.
-
-== Comments
-
-Standard Ruby comments (beginning with "#") can be used anywhere it is
-legal in Ruby source code, including comments for tasks and rules.
-However, if you wish a task to be described using the "-T" switch,
-then you need to use the +desc+ command to describe the task.
-
-=== Example:
-
-  desc "Create a distribution package"
-  task :package => [ ... ] do ... end
-
-The "-T" switch (or "--tasks" if you like to spell things out) will
-display a list of tasks that have a description.  If you use +desc+ to
-describe your major tasks, you have a semi-automatic way of generating
-a summary of your Rake file.
-
-  traken$ rake -T
-  (in /home/.../rake)
-  rake clean            # Remove any temporary products.
-  rake clobber          # Remove any generated file.
-  rake clobber_rdoc     # Remove rdoc products
-  rake contrib_test     # Run tests for contrib_test
-  rake default          # Default Task
-  rake install          # Install the application
-  rake lines            # Count lines in the main rake file
-  rake rdoc             # Build the rdoc HTML Files
-  rake rerdoc           # Force a rebuild of the RDOC files
-  rake test             # Run tests
-  rake testall          # Run all test targets
-
-Only tasks with descriptions will be displayed with the "-T" switch.
-Use "-P" (or "--prereqs") to get a list of all tasks and their
-prerequisites.
-
-== Namespaces
-
-As projects grow (and along with it, the number of tasks), it is
-common for task names to begin to clash.  For example, if you might
-have a main program and a set of sample programs built by a single
-Rakefile.  By placing the tasks related to the main program in one
-namespace, and the tasks for building the sample programs in a
-different namespace, the task names will not will not interfere with
-each other.
-
-For example:
-
-  namespace "main" do
-    task :build do
-      # Build the main program
-    end
-  end
-
-  namespace "samples" do
-    task :build do
-      # Build the sample programs
-    end
-  end
-
-  task :build => ["main:build", "samples:build"]
-
-Referencing a task in a separate namespace can be achieved by
-prefixing the task name with the namespace and a colon
-(e.g. "main:build" refers to the :build task in the +main+ namespace).
-Nested namespaces are supported, so
-
-Note that the name given in the +task+ command is always the unadorned
-task name without any namespace prefixes.  The +task+ command always
-defines a task in the current namespace.
-
-=== FileTasks
-
-File task names are not scoped by the namespace command.  Since the
-name of a file task is the name of an actual file in the file system,
-it makes little sense to include file task names in name space.
-Directory tasks (created by the +directory+ command) are a type of
-file task and are also not affected by namespaces.
-
-=== Name Resolution
-
-When looking up a task name, rake will start with the current
-namespace and attempt to find the name there.  If it fails to find a
-name in the current namespace, it will search the parent namespaces
-until a match is found (or an error occurs if there is no match).
-
-The "rake" namespace is a special implicit namespace that refers to
-the toplevel names.
-
-If a task name begins with a "^" character, the name resolution will
-start in the parent namespace.  Multiple "^" characters are allowed.
-
-Here is an example file with multiple :run tasks and how various names
-resolve in different locations.
-
-  task :run
-
-  namespace "one" do
-    task :run
-
-    namespace "two" do
-      task :run
-
-      # :run            => "one:two:run"
-      # "two:run"       => "one:two:run"
-      # "one:two:run"   => "one:two:run"
-      # "one:run"       => "one:run"
-      # "^run"          => "one:run"
-      # "^^run"         => "rake:run" (the top level task)
-      # "rake:run"      => "rake:run" (the top level task)
-    end
-
-    # :run       => "one:run"
-    # "two:run"  => "one:two:run"
-    # "^run"     => "rake:run"
-  end
-
-  # :run           => "rake:run"
-  # "one:run"      => "one:run"
-  # "one:two:run"  => "one:two:run"
-
-== FileLists
-
-FileLists are the way Rake manages lists of files.  You can treat a
-FileList as an array of strings for the most part, but FileLists
-support some additional operations.
-
-=== Creating a FileList
-
-Creating a file list is easy.  Just give it the list of file names:
-
-   fl = FileList['file1.rb', file2.rb']
-
-Or give it a glob pattern:
-
-   fl = FileList['*.rb']
-
-== Odds and Ends
-
-=== do/end versus { }
-
-Blocks may be specified with either a +do+/+end+ pair, or with curly
-braces in Ruby.  We _strongly_ recommend using +do+/+end+ to specify the
-actions for tasks and rules.  Because the rakefile idiom tends to
-leave off parentheses on the task/file/rule methods, unusual
-ambiguities can arise when using curly braces.
-
-For example, suppose that the method +object_files+ returns a list of
-object files in a project.  Now we use +object_files+ as the
-prerequisites in a rule specified with actions in curly braces.
-
-  # DON'T DO THIS!
-  file "prog" => object_files {
-    # Actions are expected here (but it doesn't work)!
-  }
-
-Because curly braces have a higher precedence than +do+/+end+, the
-block is associated with the +object_files+ method rather than the
-+file+ method.
-
-This is the proper way to specify the task ...
-
-  # THIS IS FINE
-  file "prog" => object_files do
-    # Actions go here
-  end

-= Why rake?
-
-Ok, let me state from the beginning that I never intended to write this
-code.  I'm not convinced it is useful, and I'm not convinced anyone
-would even be interested in it.  All I can say is that Why's onion truck
-must by been passing through the Ohio valley.
-
-What am I talking about? ... A Ruby version of Make.
-
-See, I can sense you cringing already, and I agree.  The world certainly
-doesn't need yet another reworking of the "make" program.  I mean, we
-already have "ant".  Isn't that enough?
-
-It started yesterday.  I was helping a coworker fix a problem in one of
-the Makefiles we use in our project.  Not a particularly tough problem,
-but during the course of the conversation I began lamenting some of the
-shortcomings of make.  In particular, in one of my makefiles I wanted to
-determine the name of a file dynamically and had to resort to some
-simple scripting (in Ruby) to make it work.  "Wouldn't it be nice if you
-could just use Ruby inside a Makefile" I said.
-
-My coworker (a recent convert to Ruby) agreed, but wondered what it
-would look like.  So I sketched the following on the whiteboard...
-
-    "What if you could specify the make tasks in Ruby, like this ..."
-
-      task "build" do
-        java_compile(...args, etc ...)
-      end
-
-    "The task function would register "build" as a target to be made,
-    and the block would be the action executed whenever the build
-    system determined that it was time to do the build target."
-
-We agreed that would be cool, but writing make from scratch would be WAY
-too much work.  And that was the end of that!
-
-... Except I couldn't get the thought out of my head.  What exactly
-would be needed to make the about syntax work as a make file?  Hmmm, you
-would need to register the tasks, you need some way of specifying
-dependencies between tasks, and some way of kicking off the process.
-Hey!  What if we did ... and fifteen minutes later I had a working
-prototype of Ruby make, complete with dependencies and actions.
-
-I showed the code to my coworker and we had a good laugh.  It was just
-about a page worth of code that reproduced an amazing amount of the
-functionality of make.  We were both truly stunned with the power of
-Ruby.
-
-But it didn't do everything make did.  In particular, it didn't have
-timestamp based file dependencies (where a file is rebuilt if any of its
-prerequisite files have a later timestamp).  Obviously THAT would be a
-pain to add and so Ruby Make would remain an interesting experiment.
-
-... Except as I walked back to my desk, I started thinking about what
-file based dependencies would really need.  Rats!  I was hooked again,
-and by adding a new class and two new methods, file/timestamp
-dependencies were implemented.
-
-Ok, now I was really hooked.  Last night (during CSI!) I massaged the
-code and cleaned it up a bit.  The result is a bare-bones replacement
-for make in exactly 100 lines of code.
-
-For the curious, you can see it at ...
-* doc/proto_rake.rdoc
-
-Oh, about the name.  When I wrote the example Ruby Make task on my
-whiteboard, my coworker exclaimed "Oh! I have the perfect name: Rake ...
-Get it?  Ruby-Make. Rake!"  He said he envisioned the tasks as leaves
-and Rake would clean them up  ... or something like that.  Anyways, the
-name stuck.
-
-Some quick examples ...
-
-A simple task to delete backup files ...
-
-   task :clean do
-     Dir['*~'].each {|fn| rm fn rescue nil}
-   end
-
-Note that task names are symbols (they are slightly easier to type
-than quoted strings ... but you may use quoted string if you would
-rather). Rake makes the methods of the FileUtils module directly
-available, so we take advantage of the <tt>rm</tt> command.  Also note
-the use of "rescue nil" to trap and ignore errors in the <tt>rm</tt>
-command.
-
-To run it, just type "rake clean".  Rake will automatically find a
-Rakefile in the current directory (or above!) and will invoke the
-targets named on the command line.  If there are no targets explicitly
-named, rake will invoke the task "default".
-
-Here's another task with dependencies ...
-
-   task :clobber => [:clean] do
-     rm_r "tempdir"
-   end
-
-Task :clobber depends upon task :clean, so :clean will be run before
-:clobber is executed.
-
-Files are specified by using the "file" command.  It is similar to the
-task command, except that the task name represents a file, and the task
-will be run only if the file doesn't exist, or if its modification time
-is earlier than any of its prerequisites.
-
-Here is a file based dependency that will compile "hello.cc" to
-"hello.o".
-
-   file "hello.cc"
-   file "hello.o" => ["hello.cc"] do |t|
-     srcfile = t.name.sub(/\.o$/, ".cc")
-     sh %{g++ #{srcfile} -c -o #{t.name}}
-   end
-
-I normally specify file tasks with string (rather than symbols).  Some
-file names can't be represented by symbols.  Plus it makes the
-distinction between them more clear to the casual reader.
-
-Currently writing a task for each and every file in the project would be
-tedious at best.  I envision a set of libraries to make this job
-easier.  For instance, perhaps something like this ...
-
-   require 'rake/ctools'
-   Dir['*.c'].each do |fn|
-     c_source_file(fn)
-   end
-
-where "c_source_file" will create all the tasks need to compile all the
-C source files in a directory.  Any number of useful libraries could be
-created for rake.
-
-That's it.  There's no documentation (other than whats in this
-message).  Does this sound interesting to anyone?  If so, I'll continue
-to clean it up and write it up and publish it on RAA.  Otherwise, I'll
-leave it as an interesting exercise and a tribute to the power of Ruby.
-
-Why /might/ rake be interesting to Ruby programmers.  I don't know,
-perhaps ...
-
-* No weird make syntax (only weird Ruby syntax :-)
-* No need to edit or read XML (a la ant)
-* Platform independent build scripts.
-* Will run anywhere Ruby exists, so no need to have "make" installed.
-  If you stay away from the "sys" command and use things like
-  'ftools', you can have a perfectly platform independent
-  build script.  Also rake is only 100 lines of code, so it can
-  easily be packaged along with the rest of your code.
-
-So ... Sorry for the long rambling message.  Like I said, I never
-intended to write this code at all.

-    # Create a documentation task that will generate the RDoc files for

-    #
-    # The RDocTask will create the following targets:

-    #   Main task for this RDOC task.
-    #
-    # [<b>:clobber_<em>rdoc</em></b>]

-    #
-    # [<b>:re<em>rdoc</em></b>]
-    #   Rebuild the rdoc files from scratch, even if they are not out
-    #   of date.
-    #
-    # Simple Example:
-    #
-    #   Rake::RDocTask.new do |rd|
-    #     rd.main = "README.rdoc"
-    #     rd.rdoc_files.include("README.rdoc", "lib/**/*.rb")

-    #
-    # == Specifying different task names
-    #
-    # You may wish to give the task a different name, such as if you are
-    # generating two sets of documentation.  For instance, if you want to have a
-    # development set of documentation including private methods:
-    #
-    #   Rake::RDocTask.new(:rdoc_dev) do |rd|
-    #     rd.main = "README.doc"

-    # first argument. With the <tt>:rdoc</tt>, <tt>:clobber_rdoc</tt> and
-    # <tt>:rerdoc</tt> options, you can customize the task names to your liking.
-    # For example:

-    #   Rake::RDocTask.new(:rdoc => "rdoc", :clobber_rdoc => "rdoc:clean", :rerdoc => "rdoc:force")
