o Fast operation on large file (100M+) via optimize I/O library
o Multi-language and template support, easy customization
o Fully UTF-8 and multi-charset conversion support, eg CJK.

Prerequisites:
==============
perl 5.006 or above, 5.008 is recommended
Encode (2.0 or higher) or Text::Iconv
Module DB_File (already include in perl)
Module Symbol (already include in perl)
Module Fcntl (already include in perl)
A working web server with CGI support, apache is recommended
using tools/pkg_stats.sh to check which module required is not present:
# cd /path/to/extmail-source
# . ./tools/pkg_stats.sh
Optional modules:
=================
Net::LDAP - need this if ldap authentication activated
DBI - need this if mysql authentication activated
Benchmark - need this if developer want debug information
Recommand software
==================
For reducing effort, we highly recommand that use pre-complied software,
such as RPM or BSD pkgs, including perl, apache, and mysql or ldap etc..
Linux - RPM/deb is prefer
FreeBSD - pkg is prefer
Directory
=========
html - the template directory, every theme should have a sub directory
cgi - the cgi scripts directory
libs - the extmail lib and related packages
lang - I18n locale directory, translator may want to look at it :)
tools - include session cleanup and some useful small tools
INSTALL
=======
See INSTALL in the latest distribution
FastCGI Support
===============
Since 0.23-20060104 extmail ship with FastCGI support, please refer to the
README.fcgi to get help in detail
Drawbacks:
==========
o not support mbox/mbx or imap/pop3, but why mb*/pop3/imap?
o Too simple, but complex make things mass and slow, why complex?
