Mk4tcl - Tcl binding for Metakit embedded database library

Metakit is an efficient embedded database library with a small footprint.
It fills the gap between flat-file, relational, object-oriented, and
tree-structured databases, supporting relational joins, serialization,
nested structures, and instant schema evolution. There is a C++ API,
a Python binding called Mk4py, and a Tcl binding called Mk4tcl.
You can manipulate and exchange data between any of these.

Data files are portable. The library has been used on Unix, Windows,
Macintosh, VMS, and others, spanning a range of 16- to 64-bit architectures,
from PDA's to S390's.

Metakit is in use in various commercial projects and products on millions
of desktops.
