I've followed the instructions:
http://www.garbagecollect.jp/ruby/mswin32/en/documents/install.html
but failed to get it running.
"
C:\>ri class
C:\ruby\bin\ruby: no such file to load -- ubygems (LoadError)
"
can someone please post the output of "ri class", thus I can verify if
something has changed?
Thank you in advance.

[as a sidenote]
Any suggestion for recreating the exact class-definition?

Any suggestion for recreating the exact class-definitions, including
source-code (recreating the executable ruby-code)?

.
----------------------------------------------------------- Object#class
obj.class => class
------------------------------------------------------------------------
Returns the class of _obj_, now preferred over +Object#type+, as an
object's type in Ruby is only loosely tied to that object's class.
This method must always be called with an explicit receiver, as
+class+ is also a reserved word in Ruby.
1.class #=> Fixnum
self.class #=> Object

Thanks - and my apologies!
This seems to be case sensitive.
ri Class (with upper case "C") should bring up another documentation.
may one can post this?
.
-------------------------------------------------- Class: Class < Module
Classes in Ruby are first-class objects---each is an instance of
class +Class+.
When a new class is created (typically using +class Name ... end+),
an object of type +Class+ is created and assigned to a global
constant (+Name+ in this case). When +Name.new+ is called to create
a new object, the +new+ method in +Class+ is run by default. This
can be demonstrated by overriding +new+ in +Class+:
class Class
alias oldNew new
def new(*args)
print "Creating a new ", self.name, "\n"
oldNew(*args)
end
end
class Name
end
n = Name.new
_produces:_
Creating a new Name
Classes, modules, and objects are interrelated. In the diagram that
follows, the vertical arrows represent inheritance, and the
parentheses meta-classes. All metaclasses are instances of the
class `Class'.

"vertical" has been added before "arrows".
Thanks for the correction.

"
so, the minimum correction would be:
additional text:
"the vertical arrows represent XXXX"

The reason you are getting that error is you have 'rubygems' in your
RUBYOPT environment variable but you have not installed rubygems yet.
You probably had everything setup correctly for 1.8.3 (w/ gems
installed with enviroment variable).. you just need to reinstall
rubygems to get rid of that error. That or clear the RUBYOPT
environment variable.
