Subject: [Freeciv-Dev] Blitzkrieg patch
From: Reed Meyer <rdm@xxxxxxxxxxxxxx>

Hello all,
     Here is a patch for the Wonder of the World "Blitzkrieg", for freeciv
1.11.0.  In fact, it is just an extraction of the relevant files from the
larger "Fascism" patch (see relevant threads).  Unlike some elements of
the general "Fascism" patch which are inflammatory to some, the Blitzkrieg
wonder has nothing to do with any particular nation or form of government,
and therefore was extracted for hopeful approval to be patched into the
main freeciv distribution.
     IMHO, "Blitzkrieg" is a good idea for a Wonder and is very powerful,
rivalling the power of "must have" Wonders like the Pyramids and Hoover
Dam.  It is a very simple concept -- in essence, a Magellan's Expedition
applying to land units.  It and other "non-Civ II" features of freeciv
should not be condemned for being "non-Civ II", but instead should be
EMBRACED for making freeciv unique and fresh, rather than a regular
rip-off of Civ II which is what freeciv otherwise would just be.  If a
user insists on playing by strict "Civ II" rules, he can set the tech
requirement to "Never" so that it can never be built.

Cheers,
---Reed Meyer
   please respond to rdm@xxxxxxxxxxxxxx

Here's the patch:  (filename:  blitzkrieg_totalpatch-1.11.0)
============================================================

Patch to Freeciv to handle the Blitzkrieg Wonder.
Includes both the source code patch and the patch to buildings.ruleset.
By Reed D. Meyer (rdm@xxxxxxxxxxxxxx).  Freeciv 1.11 patch finished 7/23/00.

**************************************************************************
NOTE!!!!!!!!!!  If the Fascism government patch is not installed, you will
need to change the line "tech_req" in the buildings.ruleset patch (at the
end of this file) to something other than "Fascism".  "Communism" might be
an appropriate alternative.
**************************************************************************

To patch, copy this file to your Freeciv 1.11 main directory, then type:
        patch -p0 < blitzkrieg_totalpatch-1.11.0

To undo the patch, type:
        patch -R -p0 < blitzkrieg_totalpatch-1.11.0
