-MailAddress is a simple email address parser.
-This library is implemented based on Perl Module Mail::Address and added some improvements.
+MailAddress is a port of Mail::Address from Perl.
 
-[mail](https://github.com/mikel/mail) is a great gem library. But some email addresses (mostly are violated RFC) are unparsable with mail gem which is strictly RFC compliant. In perl, [Mail::Address](http://search.cpan.org/~markov/MailTools-2.14/lib/Mail/Address.pod) is a very common library to parse email address. Mail::Address conviniently can parse even RFC-violated email addresses such as:
+[mail](https://github.com/mikel/mail) is a great gem library. But some email addresses are unparsable with it. In perl, [Mail::Address](http://search.cpan.org/~markov/MailTools-2.14/lib/Mail/Address.pod) is a very common library to parse an email address. Mail::Address conviniently can parse even NOT RFC-compliant email addresses such as:
 
 ```rb
 # mail gem cannot parse the following addresses
 Ello [Do Not Reply] <[e-mail]> # [, ] are not permitted according to RFC5322
-大阪 太郎<[e-mail]> # no whitespace just before <
+大阪 太郎<[e-mail]> # no whitespace just before `<`
 ```
+But Mail::Address has some bad points (below). These are fixed in MailAddress.
 
-So I straightforwardly converted Perl module Mail::Address to Ruby gem. Then I reviced it because original Mail::Address also has some bad points. For example:
-
 - if no ending parenthesis in name part, cannot parse correctly.
 - Modifications of name part are too much.
 
+However, MailAddress module cannnot parse whitespace-separated addresses.
+Many people could paste email addresses from Excel or the other spreadsheets. To accomplish this, also ported from a parser part of [Google Closure Library](https://github.com/google/closure-library/blob/master/closure/goog/format/emailaddress.js).
