Ruby中的行注释？
我如何评论Ruby中的多行？
#!/usr/bin/env ruby
=begin
Every body mentioned this way
to have multiline comments.
The =begin and =end must be at the beginning of the line or
it will be a syntax error.
=end
puts "Hello world!"
<<-DOC
Also, you could create a docstring.
which...
DOC
puts "Hello world!"
"..is kinda ugly and creates
a String instance, but I know one guy
with a Smalltalk background, who
does this."
puts "Hello world!"
##
# most
# people
# do
# this
__END__
But all forgot there is another option.
Only at the end of a file, of course.
=begin
My
multiline
comment
here
=end
尽管=begin和=end的存在，正常和更正确的评论方式是在每一行上使用# 。 如果你阅读任何ruby库的源代码，你会发现这是几乎所有情况下多行注释的方式。
