  - [scalable](./scalable) contains the source files and render scripts for all symbolic icons.
  - [cursors](./cursors) contains the source files and render scripts for the cursor theme.
  - [symlinks](./symlinks) contains the data lits and generation scripts to create symbolic links the icon theme.
