"Because it's written it generic ANSI-C, hamsterdb runs on many
architectures including Intel/AMD, PowerPC, UltraSPARC, ARM, RISC,
and others. Tested operating systems include Win32, Win64, Windows
CE, Linux, and Solaris 9. The file formats are OS independent so
you can read a file written in Solaris 9 on Windows and
vice-versa...Hamsterdb has your choice of two hassle-free licenses:
GNU Public License 2 for non-commerical use or a close-source
license for commercial use where you buy as many developer seats as
you need."
