# for running cpuminer on linux (debian) servers:
#
# 1. install essential packages
#
# $ sudo apt-get -y install gcc gcc-4.5 g++ g++-4.5 libstdc++6-4.5-dev libpcre3-dev libcurl3-dev make automake less git
#
# 2. clone cpuminer's repository
#
# ex)
#
#   $ git clone git://github.com/pooler/cpuminer.git
#
# 3. build cpuminer
#
# ex)
#
#   $ cd cpuminer
#   $ ./autogen.sh
#   $ ./configure CFLAGS="-O3"
#   $ make
#
# 4. copy this script to /etc/init.d/
#
# $ sudo cp bitcoin-cpuminer /etc/init.d/
# $ sudo chmod +x /etc/init.d/bitcoin-cpuminer
#
# 5. edit the init script (marked as 'XXX')
#
# $ sudo vi /etc/init.d/bitcoin-cpuminer
#
# 6. run as service
#
# $ sudo update-rc.d bitcoin-cpuminer defaults
#
# 7. reboot or start the service manually
#
# $ sudo shutdown -r
#
# or
#
# $ sudo service bitcoin-cpuminer start
#
