Stops execution of the current thread, putting it into a “sleep” state, and schedules execution of another thread.

a = Thread.new { print "a"; Thread.stop; print "c" }
sleep 0.1 while a.status!='sleep'
print "b"
a.run
a.join
#=> "abc"

Returns true if thr is dead or sleeping.

a = Thread.new { Thread.stop }
b = Thread.current
a.stop?   #=> true
b.stop?   #=> false

Registers _filename_ to be loaded (using Kernel::require)
the first time that _const_ (which may be a String or
a symbol) is accessed.

   autoload(:MyModule, "/usr/local/lib/modules/my_module.rb")

If const is defined as autoload, the file name to be loaded is replaced with filename. If const is defined but not as autoload, does nothing.

Returns filename to be loaded if name is registered as autoload.

autoload(:B, "b")
autoload?(:B)            #=> "b"

Deprecated. Use block_given? instead.

With string object given, returns true if path is a string path leading to a directory, or to a symbolic link to a directory; false otherwise:

File.directory?('.')              # => true
File.directory?('foo')            # => false
File.symlink('.', 'dirlink')      # => 0
File.directory?('dirlink')        # => true
File.symlink('t,txt', 'filelink') # => 0
File.directory?('filelink')       # => false

Argument path can be an IO object.

Returns true if the file at path new is newer than all the files at paths in array old_list; false otherwise.

Argument new and the elements of old_list should be interpretable as paths:

FileUtils.uptodate?('Rakefile', ['Gemfile', 'README.md']) # => true
FileUtils.uptodate?('Gemfile', ['Rakefile', 'README.md']) # => false

A non-existent file is considered to be infinitely old.
