1. Install BLT for your Tcl/Tk.
   When your Tcl/Tk and BLT libraries are installed at /usr/lib and 
   your Ruby libraries are installed at /usr/local/lib, you may have 
   to make a symbolic link '/usr/local/lib/blt' -> '/usr/lib/blt' 
   because of Tcl/Tk's library search path. 

2. Please try "ruby <ruby-lib-path>/tkextlib/pkg_checker.rb". 
   If its output includes "Ready : blt.rb : ...", your Ruby/Tk is 
   ready to use BLT. 
   When includes "LACK : blt.rb : ...", please check Tcl/Tk's 
   library path on your Ruby/Tk.
   If you need some setup operation (e.g. add a library path), 
   you can add the operation on "tkextlib/blt/setup.rb" or 
   "tkextlib/setup.rb" which are loaded before trying to load BLT 
   library.

3. "require 'tkextlib/blt'" in your script.

Please get the latest version of tkextlib/blt/* from CVS.
On the versions before 2006/11/07, tkextlib/blt/table.rb doesn't work.

If you see bugs or lack of support, please report it to me. 
I need help to find and fix such defects. 

# A latest example of improvement based on a user's report is 
# "tkextlib/tile/treeview.rb".
