ArgyllCMS
Calibeam reads your meter through ArgyllCMS 3.5.0, by Graeme W. Gill (argyllcms.com). It includes these ArgyllCMS programs, unmodified, and runs each one as a separate program:
spotread, on macOS and Windows, which takes the meter readingsoeminst, on macOS, which converts meter correction files
Calibeam’s own code is not part of these programs and is not linked into them. Together they are distributed under the GNU Affero General Public License, version 3; some of their source files carry the GNU GPL or MIT-style licenses. Calibeam’s terms do not apply to these programs, and nothing in them limits your rights under those licenses.
Source code
The complete corresponding source for the ArgyllCMS programs in Calibeam is free to download:
downloads.calibeam.app/source/argyllcms/3.5.0/
- Argyll_V3.5.0_src.zip: the ArgyllCMS 3.5.0 source, as published by its author
- ajam-2.5.2-1.3.3.tgz: the source of the build tool ArgyllCMS uses
- README.txt: what Calibeam includes, and the exact build steps
- SHA256SUMS: checksums for every file in the folder
The folder also holds the scripts Calibeam builds the macOS programs with, and
every license text. The Windows spotread.exe is the unmodified build
published by ArgyllCMS, made from the same source.
Each Calibeam release names the ArgyllCMS version it includes, and the source for that version stays available for as long as the release is offered.
