Cathisma is a typeface used for decorative titles in liturgical books of the Russian Orthodox Church published since the late 19th century.
The font was originally designed by Vlad Dorosh as Kathisma UCS for the Irmologion project. It was then released under the LaTeX Project Public License as part of CSLTeX. Next, it was reencoded for Unicode by Aleksandr Andreev and released as Cathisma Unicode, part of the Slavonic Computing Initiative, and released under SIL OFL v. 1.1. Edited by Aleksandr Andreev.

The font is built using fontmake and gftools post processing script. Tools are all python based, so it must be previously installed.
To install all the Python tools into a virtualenv, do the following:
From terminal:
cd your/local/project/directory
#once in the project folder create a virtual environment.
This step has to be done just once, the first time:
python3 -m venv venv
#activate the virtual environment
source venv/bin/activate
#install the required dependencies
pip install -r requirements.txt
Then run the this command:
cd sources
gftools builder config.yaml
The fonts are supposed to build automatically in the repository using GitHub Actions, but this does not work correctly for some reason.
There are no specialized features. Only glyphs used in titling are provided in the font.
