Implements customized behavior.
Some behaviors need to vary when packaged for certain platforms. For instance,
while Cedar Backup generally uses cdrecord and mkisofs, Debian ships compatible
utilities called wodim and genisoimage. I want there to be one single place
where Cedar Backup is patched for Debian, rather than having to maintain a
variety of patches in different places.
