-
-1.1.0 ABOUT RELEASES 
-
-There are several projects involved:
-
-- The chat -
-Its a HTTP based chat server written in C++. Clients are normal web browsers 
-such as MSIE or Gecko based browsers using only CSS, HTML and JavaScript. 
-
-- The httpd -
-Its a small http server based on the chat's socket and threading engine.
-yhttpd does not have as much features but is easy to use and faster than
-apache. yhttpd is a subset of the chat. It can be generated using the
-srcipts/yhttpdbase.pl script in the chat's source tree. 
-
-- The ycurses -
-ycurses is a easy to use and small C++ wrapper around the C ncurses API. 
-
-There are different branches:
-
-- CURRENT - 
-The CURRENT branch is unstable, this is the bleeding developing edge with 
-all the new experimental features.
-
-A RELEASE of CURRENT can be referred as CURRENTRELEASE.
-
-- STABLE -
-The STABLE branch is more stable than CURRENT. This branch may get new
-features as well. But those will be more conservative compared to 
-CURRENT.
-
-A RELEASE of STABLE can be referred as STABLERELEASE.
-
-- LEGACY -
-The LEGACY branch has no real support. This branch may get bugfixes and
-updates and might get minor improvements. But there is no garuantee to
-be bug free and stable at all. LEGACY versions are of historic meaning. 
-
-- DEVEL -
-DEVEL is only a meta name. If a version is labeled with DEVEL, then its
-currently undefined if this is a CURRENT, STABLE or LEGACY branch. It
-can be everything. Commonly DEVEL versions are CURRENT. 
-
-There are also releases made:
-
-- RELEASE -
-There can be RELEASEs made out of each branch. While a branch can get
-new features, a RELEASE can not. A RELEASE of a branch is just like
-a snapshot. RELEASEs are complete versions to test and use. But keep
-in mind, that a RELEASE of the STABLE branch is recommended over a
-RELEASE of a CURRENT or a LEGACY branch in a production environment.
-RELEASEs of CURRENT are still the bleeding edge and RELEASEs of LEGACY
-may be out of date.
-
-- Short names -
-
-In addition, each description also has short names: (short names are needed 
-if your text space is limited which happens very fast in IRC channel topics)
-
-CURRENT aka CUR aka C
-RELEASE aka REL aka R
-LEGACY  aka LEG aka L
-STABLE  aka SBL aka S
-DEVEL   aka DEV aka D
-PRE     aka P
-
-STABLERELEASE aka STBREL aka SR
-PRERELEASE aka PREREL aka PR
-PRELEGACYRELEASE aka PRELEGREL aka PLR
-etc...
-
-The short name of the chat is "yC"
-The short name of the httpd is "yh"
-The short name of ycurses is "yu"
-

-1.2.0 YCHAT FEATURES
-
-- Its free & portable -
-yChat is developed under the GNU general public license and is based on GNU 
-tools (gcc, gmake), other open source library stuff (such as libncurses etc.)
-and should run on any POSIX capable operating system (such as all Linux based 
-systems, FreeBSD, NetBSD, OpenBSD and other BSD-Systems and on UNICES like 
-IRIX, HP-UX, Solaris etc.).
-
-- There is no need for special chat clients -
-yChat is web based, that means clients may only connect to the chat server 
-with an normal web browser such as Microsoft Internet Explorer or any Gecko-
-Engine powerd browsers like Mozilla, Firefox, Camino etc.
-
-- It has features of a real HTTP webserver -
-yChat runs completely stand alone and does not need another webserver to build
-on like Apache and does not need to be run via any kind of CGI. yChat creates 
-its own socket on a customized port (standard port: 2000) and seems to be a full
-featured HTTP web server to the clients (web browsers). 
-
-The yChat code base can be converted to an yhttpd code base automaticaly. yhttpd
-is the webserver subset of yChat which runs completely stand alone and provides
-normal websites to the net. It also supports Common Gateway Interface (CGI)
-scripting.
-
-- Its fast and secure -
-yChat is written in C++ which is faster than any Java based Chat-Server or any
-server written in a scripting language like PHP, Python or Perl. As the
-internal data structures hash maps are used to garuantee searching certain
-values in O(1) amount of time. If a hash maps gets full, it will be rehashed.
-Currently, yChat has been measured providing over 1000 hits/requests per second 
-on a FreeBSD based server box while using less than 2% of CPU usage
-on a Athlon XP 1900+. Performance seems to be limited by your bandwith only. 
-Also, each user gets its own session id (random string) with a standard length 
-of 50 chars to authenticate each logged in user. The length of the session id 
-can be redefined as well. Also, the session id will get md5-hashed optionally 
-so thats even harder to reverse engineering the session ids of other users.
-Also, yChat supports secure hypertext transfer protocol (HTTPS) connections
-using the OpenSSL library. Then, all chat messages will be encrypted in a
-secure manner. HTTPS is optional to HTTP (unsecured connections). 
-
-- Its HTML template based and easy to customize via XML based configuration -
-All HTML sites are predefined as HTML-Template files and can be easily modified
-to use with an customized web design. Also, a lot of yChat preferences can be
-set in the main configuration file (ychat.conf). ychat.conf is completely written
-in XML 1.0 which makes it easier to use the configuration options in programs of
-3rd persons which may want to write some usefull tools for yChat.
-yChat caches all HTML and web images to improve overall performance. If needed, the
-cache can be cleared to recache new versions of the template files.
-
-- Its language template based -
-The administrator can easily create a new language in which all system messages
-appear to the Chat-User. The predefined languages is english but others can be
-added easily. The language can be edited in the XML based configuration file.
-
-- MySQL based database -
-Registered users are stored in a MySQL database. C++ Programmers may feel free
