`IRB::Pager` vs. `Pager`
====================

Because naming conflicts,  i renamed Pager to `IRB::Pager`.
There is no need for `IRB`;  of course you can use `IRB::Pager` without `irb`.

I renamed these things:

* gem: `gem install pager` #=> `gem install irb-pager`
* lib: `require 'pager'` #=> `require 'irb-pager'`
* module: `Pager` #=> `IRB::Pager`

`Pager.pager` will be `IRB::Pager.pager` now.

Usage
=====

Very simple:

	require 'irb-pager'
	include IRB::Pager
	pager { puts "Hello World!" }
	pager { 1.upto(200) {|i|sleep 0.2; puts i} }

Exceptions will not be handled by pager:

	pager { raise 'Oops' }

But if you want, pager can do:

	pager( :rescuing => true) { raise 'Oops' }
	$PAGER_RESCUE = true  # forces pager to handle exceptions everytime.
	pager { raise 'Oops' }

You like more more than less?  (I cannot understand, but it is your choice)

	pager( :pager => 'more') { puts "Hello World!" }
	$PAGER = 'more' # forces pager to use more
	pager { puts "Hello World!" }

If you have set `PAGER` in your Processenvironment (`/etc/profile` or `~/.profile` ...) this `PAGER` will be used.

	PAGER=more
	export PAGER
