The `debian/missing-sources` directory contains the SASS sources needed to
build the theme CSS.
The procedure for updating them is as follows:
- Install the latest versions of node.js and npm.
- Install the JavaScript dependencies using `npm install`.
- Copy `bourbon`, `bourbon-neat` and `wyrm` directories from `node_modules`
to `debian/missing-sources`.
The following components are copied:
Name | Website | WNPP bug | Currently used version
------------ | ----------------------------- | -------- | ----------------------
bourbon | https://www.bourbon.io/ | #892811 | 4.3.4
bourbon-neat | https://neat.bourbon.io/ | | 1.9.1
wyrm | https://github.com/snide/wyrm | | 1.0.9
Note that only the SASS files and the corresponding documentation are copied,
not the other files.
