Overview

String extensions to use the GZip module.

The methods gzip and gunzip provide an even more simple interface to the ZLib:

# create a big string
x = 'a' * 1000

# zip it
x_gz = x.gzip

# test the result
puts 'Zipped %d bytes to %d bytes.' % [x.size, x_gz.size]
#-> Zipped 1000 bytes to 19 bytes.

# unzipping works
p x_gz.gunzip == x  #-> true

#to_unix ⇒ Object

I love this hack. It seems to silence all dos/unix/mac newline problems.
