If you'd like to include a directory into the path ruby searches for
files you can use the -I command line prompt. So to add a directory
called 'lib' you'd write
ruby -Ilib program.rb

Is there any way that we include in the script itself? like in "use
FindBin qw{$RealBin}; use lib $RealBin;" which will find the present
working directory and will include that in @ISA list.

Or you can manipulate the $: variable from within ruby. It's an array which
contains the paths ruby uses when looking for required files. So, if you do

$: << 'my_lib'

you can require a file contained in the directory my_lib with

require 'my_file'

instead of using

require 'my_lib/my_file'

I hope this helps

To automatically require all files in a directory?
Some variation of the following might do the trick...

Dir.glob('./directory/*').each do |lib|
require lib
end

Hope that helps.

I prefere
$:.unshift 'my_lib'
because this way the path 'my_lib' is prepended to the array and you can
be sure the file in this directory will be found even if another with
the same name exist somewhere else in the search path.
