ODCL is a package of utility functions maintained by onShore Development. It is required by UnCommonSQL and IMHO.

The home page for ODCL is http://alpha.onshored.com/lisp-software/#odcl. [This link has been down for over a month]. The software is available in Debian as cl-odcl, though it is no longer maintained. This package has been orphaned by onShore Development.

An asdf'ified version is available in vn-cCLan.
