here is Cdb[1] reader and creator, in two small modules.

reader: [2]
creator: [3]
sample: [4]

it's totally untested, but i believe that is works. at least for the given sample.

Hi, i'd have a technical question about cdb, maybe a bit off-topic...

Why it was designed to use 256 hashtables ?
Why not single bigger 252 * 256 hashtable ?

Is it only to save space or there are some other reason ?

i honestly don't know. but i bet DJB knows. ;-)

my goal was to simply create cdb-compatible code, so i can work with cdb databases without resorting to C library.
