Focused software built from real engineering needs.

Delta OTA is an over-the-air software distribution system for large packages. It is designed for deployments where full redownloads are too slow, too expensive, or too unreliable for users.

The public project is dual-licensed: AGPL for open-source use and commercial licensing for proprietary distribution.

clautolisp is an AutoLISP and Visual LISP implementation hosted in Common Lisp. It runs AutoLISP code headlessly, without a CAD session, and drives AutoCAD and BricsCAD from the same command line, so CAD customisations can be tested and released like ordinary software.

It ships with a written language specification, a conformance suite, and a benchmark suite. The public project is dual-licensed: AGPL for open-source use and commercial licensing for proprietary use, with consulting and maintenance contracts available.

ALPM is a system definition and loading facility for AutoLISP, in the spirit of ASDF. Describe a library as a system with declared file and system dependencies, and ALPM computes the load order, checks every path first, and loads it identically on AutoCAD, BricsCAD, or clautolisp.

It also handles encoding-safe loading across engines, a checked exports declaration, standalone-loader and single-file generation for machines with no ALPM installed, and import/export of existing VLISP .prj/.prv projects.

ergo is a git-native package manager and project builder for Common Lisp and AutoLISP. Any git repository, public or private, is a project or a dependency — no central registry, just repositories and per-project lock files for reproducible builds.

A collection of AutoLISP tools and libraries for running code from the shell, writing macros, launching tests, experimenting with data structures, and consulting local documentation.
