The current description (sid, version 0.5.9) is a bit longer:
cdebootstrap generates systems from scratch for Debian and derivates. This is implementation is different from debootstrap. It features a different package selection. The package selection is done according to the flavour.
Assuming the part "This is" should be replaced by "This", the text doesn't make things more clear. What's a flavour, and how is the package selection different?
