# Install libtidy (needed for tidy2.0 compile)
apt-get -y install libtidy-0.99-0

# Install GNU tools for compiling
apt-get -y install build-essential

apt-get -y install libtidy-dev

# Download tidy2.0 source (this can also be found in the PHP5 sourcecode, I just tarred it up to make this easier)
wget -c http://support.office-shadow.com/installer/tidy2.0.tar.gz

# Unpack the source
tar xvzf tidy2.0.tar.gz

# Configure tidy for installed php5 API
cd tidy
phpize 

# Configure & Compile the source
./configure
make clean    <-- Without this the compile builds a bad module for some reason
make
make install

# Install module into php.ini
echo "extension=tidy.so" >> /etc/php5/apache2/php.ini;
