-## Limitations
-
-* Caution with symbolic links:
-  If you use symbolic links inside any directory of the command line arguments
-  they must not point to files or directories outside the root of the path of the
-  command line argument (i.e. --flavor-path ./flavors/my_flavor/ => There must be no symbolic
-  link inside ./flavors/my_flavor point to anywhere outside of ./flavors/my_flavor).
-  Background: Local directories paths must be mounted manually to the docker container.
-  We currently support only the mounting of the given command line arguments, but we do not analyze
-  the content of those directories.
-  Plan is to fix this limitation with [#35](https://github.com/exasol/script-languages-container-tool/issues/35)

-
-### MacOsX Limitations
-
-* On MacOsX all arguments (flavors path, output directory, etc.) must point to locations within the current directory (background is that the MacOsX version does not support mount binding additional directories).
