If you already maintain an AutoCAD/BricsCAD project file, convert it:
(alpm-import-project "/home/pjb/work/schmsplus/schmsplus.prj"
"/home/pjb/work/schmsplus/schmsplus.alpm")
This reads the project’s source list and produces a serial ALPM system with the same files in the same order (a ‘.prj’ expresses a linear order, so the import preserves it faithfully). You can then refine the generated ‘.alpm’ by hand — typically replacing ‘serial T’ with real per-file dependencies. Compile-related project settings are preserved under the system’s ‘properties’ for future use.
