Version 2.2.5 (20061110)
========================
The `uudecode' program is added to the source code. The program
is taken from the GNU sharutils 4.6.3. Unfortunaly, certain
modern Linux distrubutions (notably, Fedora Core) does not
contain the sharutils by default. Now, it is not required to
install the sharutils prior to installing ejudge.

configure
---------
Default values are provided for the following options:
--enable-socket-path, --enable-super-serve-socket,
--enable-contests-home-dir, --enable-conf-dir,
--enable-cgi-conf-dir. The values are as follow:
--enable-socket-path=/tmp/userlist-socket
--enable-super-serve-socket=/tmp/super-serve-socket
--enable-contests-home-dir=/home/judges
--enable-conf-dir=/home/judges/data
--enable-cgi-conf-dir=../cgi-data 

compile
-------
To simpify the installation and the initial configuration the
following command line options are added:
-i	initialization mode - the `compile' creates all
	necessary directories and finishes
-u USER specify the user login, which will be switched to, if
	the program is started by root
-g GRP	specify the group, which will be switched to, if the
	program is started by root. If the `-g' option is not
        specified, the group name is assumed to be equal to the
        user name.
-C DIR	specify the working directory. The `compile' program
	changes its current directory to the specified.
If the `compile' is invoked by root, the `-u' option is
required. New options are used by the `ejudge-setup' program in
the generated setup script.

New option `-D' is added - run the `compile' program in the
daemon mode.

serve
-----
To simpify the installation and the initial configuration the
following command line options are added:
-u USER specify the user login, which will be switched to, if
	the program is started by root
-g GRP	specify the group, which will be switched to, if the
	program is started by root. If the `-g' option is not
        specified, the group name is assumed to be equal to the
        user name.
-C DIR	specify the working directory. The `compile' program
	changes its current directory to the specified.
If the `compile' is invoked by root, the `-u' option is
required. New options are used by the `ejudge-setup' program in
the generated setup script.

ejudge-setup
------------
The mono programming languages (mcs and mbas) are commented out
by default in the generated config files.

The ejudge's version of uudecode program is used instead of the
system-provided.

In the generated setup scripts both the `serve' and the
`compile' programs are invoked in the initialize mode.

cmp_double, cmp_double_seq, cmp_long_double, cmp_long_double_seq
----------------------------------------------------------------
These standard checkers support the absolute error comparison
mode. In this mode the EPS environment variable specifies the
maximum allowed absolute difference between the user program
output and the correct output. This mode is invoked, if the
ABSOLUTE environment variable is specified.

libchecker
----------
New functions are added, which compare two floating-point
numbers with maximal possible ABSOLUTE difference between each
other.
int eq_double_abs(double v1, double v2, double eps);
the `v1' and `v2' are compared: if the difference between them
less than `eps', the function returns 1, and 0 otherwise.
Similar functions are provided for `float' and `long double'
types.
