TclGdbmWrapper , by Mario Weilguni, "attaches" a GDBM database to a array variable. There is no need to write any database access command, as this is done by tcl_gdbm_wrapper.tcl.
A tclsh (itclsh, itkwish, tixwish...) which supports the "gdbm" command or a version of Tcl >= 7.5 and a dynamic library "libtclgdbm-0.1.so" in any appropriate directory are needed.
A slighly-modified "tcl+gdbm" package in the directory tcl+gdbm-0.1. It allows you to create a shared library by typing "make shared". It works under Linux ELF with gcc 2.7.2. I've modified the Makefile and gdbmcmd-shared.c (which is a copy of gdbmcmd.c except for this modification). It should also work with "tcl+ndbm", but then you have to modify the line >> set DBM(DB) "gdbm" to >> set DBM(DB) "ndbm"
How it works:
It's really simple. Just take a look into demo.tcl.

I'd appreciate feedback (patches, comments...). Mail to , and please use a subject like "GDBM_WRAPPER: I have a new patch".
AMG: This code does not compile with current Tcl (8.6) due to lack of a global variable called tcl_RcFileName and due to direct access to interp->result. These issues are not hard to work around if you're familiar with Tcl's C API. Additionally, there's no main function. I'm not sure what is the recommended solution.
