How to patch in the new source - ignore the // comments :)

// backup your mud directory (especially area files).

cd dot                    
mkdir patchsrc      // create a patch folder to store the new source
cd patchsrc
cp -R ../src/* .    // copy the existing source into that folder
wget http://www.dawnoftime.org/download/dawnsrc-1.69b-1.69d.diff.gz    // download the latest patch
gunzip dawnsrc-1.69b-1.69d.diff.gz                          // uncompress the patch
patch -p1 < dawnsrc-1.69b-1.69d.diff                        // run the patch
ls -al *.rej     // list all the reject files - changes that need to be manually patched

//
// work through each one of the reject files, manually patching the changes and removing
// each reject file as you go.  You can look at the dawn release you are patching to and
// your source (in the src folder) if the reject file looks confusing in places.
//
// once hand patched the reject files, compile the patchsrc code.
// after getting compiling perfect... remove the ~ files (rm -f *.*~)
// then move the src folder to src.old and patchsrc to src.
cd ..
mv src src.old
mv patchsrc src

// All finished :)
