Subject: difference between $0 and __FILE__


i have a script in my HOME/bin :

/Users/yt/bin/path_test.rb

my "HOME/bin" is in the PATH

then, if from this script, i outputs $0 and __FILE__

with :

path_test.rb  i got :
$0 = /Users/yt/bin/path_test.rb
__FILE__ = /Users/yt/bin/path_test.rb


and the same outputs with :
/Users/yt/bin/path_test.rb

why do i have the same outputs in this case ?

in fact i'm looking that because i do have Ruby class extension in a
subfolder of "HOME/bin", namely :
HOME/bin/ruby_ext
where i put my extension for classes of which i could require :
require "#{File.dirname($0)}/ruby_ext/ansi_color"

what's the best way to require in that case, does i need an "absolute
path (starting from / ) or not ?
