# status: working
#
#
# what's it for? 
# ------------------
# for people who want to run 64-bit *.exe engines in Ubuntu, from 32-bit GUI's
# such as Arena or Aquarium. 
# 
# the script automatically compiles a 32-bit/64-bit install of wine on Ubuntu 10.10 64-bit.
# this is a temporary fix - eventually 64 bit wine will be installable from the Ubuntu 
# package manager - as is currently (written Dec 19, 2010) the case with Sabayon 5.4 and OpenSUSE 11.3.
#
#
# how to use it?
# ------------------
# 1. first, update your system. use these two lines at the command prompt:
# sudo apt-get update
# sudo apt-get upgrade
# reboot your system.
#
# 2. save the script, http://www.jesseo.com/chess/64-bit-wine-ubuntu.sh, to your 
# user's home folder /home/USERNAME
#
# 3. open a terminal and change it's permissions by entering
# sudo chmod +x 64-bit-wine-ubuntu.sh
#
# 4. run the script with the following command
# ./64-bit-wine-ubuntu.sh
#
# let it run for about an hour. it will download about 1gb of data and will compile two version of
# wine. depending on the speed of your machine
# and internet connection, the script can take a few hours. on a 800KB connection, with an i3m
# processor, it takes about 40 minuets. 
# note: don't interupt the script. it'll take a while. this message will be on the screen for a
# long time, "Configure: Finished. Do 'make' to compile wine"
#
# i hope this doesn't break your computer - 
# but i guess it could. enjoy, Jesse.

# Jakub: note, that the negation (!) is before the '['. This is different
# from [ ! "$cores" -gt 0 ], since it also catches situation
# when user didn't enter a number at all (empty string, characters), in which
# case the 'test' call fails. (-gt is numeric comparison)
