-Ruby/Tk does NOT support forking the process on which Tk interpreter
-is running (unless NEVER control Tk interpreter under the forked child
-process). In the library 'tk.rb', a Tk interpreter is initialized.
-Therefore, if you want running Tk under a child process, please call
-"require 'tk'" in the child process.
-
-# If do fork and exec(<new Ruby/Tk>) on the child process, you can
-# control Ruby/Tk interpreter on the child process by 'send' command
-# of Tcl/Tk. About this, please see Tk.appsend and Tk.rb_appsend, or
-# 'remote-tk.rb' and the sample 'sample/remote-ip_sample.rb'.
-
-For example, the following sample1 will NOT work, and sample2 will
-work properly.
-
----<sample1: NOT work>---------------------------------------
-require 'tk' ## init Tk interpreter under parent process
-
-exit! if fork ## exit parent process
-
-## child process
-TkButton.new(:text=>'QUIT', :command=>proc{exit}).pack
-Tk.mainloop
--------------------------------------------------------------
-
----<sample2: will work>--------------------------------------
-exit! if fork ## exit main process
-
-## child process
-require 'tk' ## init Tk interpreter under child process
-TkButton.new(:text=>'QUIT', :command=>proc{exit}).pack
-Tk.mainloop
