Simplified CD Backup for Linux
Backups backs up large amounts of data on one or more CDs.
No special tool is needed for reading the backup,
because mkisofs (ISO9660) and afio are used.
Since scdbackup can write more than one CD, there is
an information script stored on each CD which
tells you where a certain file may be found.
A collision test is performed to avoid aborting mkisofs.
