Markus Armbruster 6fcbc16adf update: Limit avail roll over to about half the update's work
Traditionally, unused unused available work is discarded at the
update.  Since commit d7a054c (v4.2.13), deities can configure (some)
unused work to "roll over", i.e. available work = some unused work +
this update's work.

Not discarding unused work reduces micromanagement incentives.
However, it also leads to unobvious behavior.

For instance, here's the obvious way to build a radar station: move in
enough people to make 200 work.  Half of it is available for sector
building, and increases efficiency to 100%.  Here's a not-so-obvious
way: move in enough people to make 134 work.  67 will be used to
increase efficiency to 67%.  Now move your workers elsewhere.  The
unused available work is enough to finish the job at the next update.

Similarly, neighbors could be surprised by sectors building bridges
despite having no visible workers.

Commit 7f4e59f (v4.2.15) let deities limit the amount rolled over:
unused work above rollover_avail_max is discarded.  This became the
default with a value of 50 in commit 81a3e4c4, v4.3.31.

Limit it further so that "roll over" can increase the update's work by
no more than half, plus one.  The extra point is there so that even a
tiny work force has a chance to eventually eke out the second point of
work needed to increase efficiency.

Welcome to Empire 4, code-named Wolfpack.

Empire is a multi-player, client/server Internet based war game.

This program is free software: you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation, either version 3 of the License (in file
`COPYING'), or (at your option) any later version.

See file `CREDITS' for a list of contributors.

Directory `doc' has additional information.  File `doc/README'
describes the files there and what they talk about.

To build the server and set up a game, follow the steps below.

(1) Unpacking the source tree

    If you downloaded a tarball, unpack it.

    If you cloned a git repository, run bootstrap.  This requires
    recent versions of Autoconf and Automake to be installed.  See
    also doc/contributing.

(2) Building a server

    Prerequisites: IEEE Std 1003.1-2001 (POSIX.1-2001), GNU make, a
    curses library, Perl, and either nroff or GNU troff (`groff').

    See file `INSTALL' for detailed compilation and installation
    instructions.  Quick guide for the impatient: run configure; make;
    make install.  The last step is optional; everything runs fine
    right from the build tree.

    If configure reports "terminfo: no" in its configuration summary,
    highlighting doesn't work in the client.  Commonly caused by not
    having development libraries installed.  On Linux, try installing
    ncurses-devel.

    If make fails without doing anything, you're probably not using
    GNU make.  Some systems have it installed as `gmake'.

    Solaris supports POSIX.1-2001, but you need to set up your
    environment for that.  Try passing
        SHELL=/usr/xpg4/bin/sh PATH=/usr/xpg6/bin:/usr/xpg4/bin:$PATH
    to make.  See standards(5) for details.

(3) Creating a game

    * Create a configuration for your game.  make install installs one
      in $prefix/etc/empire/econfig ($prefix is /usr/local unless you
      chose something else with configure).  You can use pconfig to
      create another one.

    * Edit your configuration file.  See doc/econfig for more
      information.

      Unless you put your configuration file in the default location
      (where make install installs it), you have to use -e with all
      programs to make them use your configuration.

    * Run files to set up your data directory.

    * Run fairland to create a world.  For a sample world, try
      `fairland 10 30'.  This creates file ./newcap_script, which will
      be used below.  You can edit it to change country names and
      passwords.

      Check out fairland's manual page for more information.

    * Start the server.  For development, you want to run it with -d
      in a debugger, see doc/debugging.  Do not use -d for a real
      game!

    * Log in as deity POGO with password peter.  This guide assumes
      you use the included client `empire', but other clients should
      work as well.

      For help, try `info'.

      To change the deity password, use `change re <password>'.

    * Create countries with `exec newcap_script'.

    Your game is now up!

Naturally, there's more to running a real game than that, but that's
beyond the scope of this file.
