-   * No headlines are shown. It is not possible to remove only one of them with CSS only (JS would be required). However, because the content in most of the lines is self-explained, it is preferred not to show any.

 * Ubuntu uses `dash` instead of `bash` when a shell script is run. As a result, some functionalities, such as arrays like ``array[1]``, are not supported. Therefore, build scripts in `dist/linux` should not use those functionalities unless they are sourced in a `bash` shell. That is, :file:`travis-ci.sh` uses arrays, since it is sourced in the Travis CI machine. But :file:`docker-buildtest.sh` and :file:`buildtest.sh` do not use any. The same applies to the scripts in `testsuite`.
