<h2>Overview</h2>
<p>Library for reading and writing zip files.</p>
<p>Examples:</p>
<p>Reading from a zip file:</p>
<p># create output MemoryIO
mem_io = MemoryIO.new</p>
<p># read from "foo.zip"
Zip.read("foo.zip") do |zip|
# read contents of "bar.txt" in "foo.zip" into mem_io
zip["bar.txt"].read(mem_io)
end</p>
<p>Writing to a zip file:</p>
<p># write to "foo.zip"
Zip.write("foo.zip") do |zip|
# create "bar.txt" with contents "hello!"
zip.add("bar.txt", "hello!")
end</p>
