- Preserve timestamps when copying files into the CDs
- Make sure build.sh can run in -e (stop on error) mode
- Report if packages needed by debootstrap is missing on a CD
- Report how much space is reserved on each CD
- Handle boot-floppy directories without documentation
CONF.sh as DEFBINSIZE and DEFSRCSIZE
build.sh and build_all.sh now use these settings to calculate the
packages and source files to go on each disk, using bc - shell
arithmetic cannot cope with > 32-bit numbers
use the md5sum from the textutils package - dpkg's md5sum cannot
handle large files.
