This site is built with a Rust based content management system (CMS).

The database can be edited and maintained with standard text editors and standard version control tools.

The CMS has a powerful macro processor to build the pages from text artifacts. The page source files in the database are a mix of HTML code and macro calls that expand to more HTML code. This makes the system very flexible and customizable.

The development source code of cms can be downloaded using the Git version control system as follows:

git clone https://git.bues.ch/git/cms.git

To browse the Git repository online, go to the repository web interface.
Or download the compressed snapshot.
A mirror of the repository is available on GitHub, GitLab, Bitbucket and on NotABug.org.
