问从Python中打开的文件中获取路径

=begin

My 

multiline

comment

here

=end

#!/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 o

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.
