Ruby has two types of comments: inline and block.
Inline comments start with the
# character and continue until
the end of the line:
# On a separate line class Foo # or at the end of the line # can be indented def bar end end
Block comments start with
=begin and end with
=end. Each should start on a separate line.
This is commented out class Foo end this works, too
=end can not be indented, so this is a
class Foo =begin Will not work =end end
