 Currently, subcommand only valid for Python script.
 There are two possible class available for this subcommand.

+To make this document can stands on its own and to remove repetitive codes, we can also include a python library inside `_build/lib` directory.
+All script above, will include all files mentioned inside `_build/lib`.
+Furthermore, the `_build/lib` will be populated by CodeBlock with `.lib` class.
+This is an example of the block:

+We can choose the representation of this block inside the pdf output by providing `description` variable.
+When there is no `description`, then this `lib` CodeBlock will be considered as a *hidden library*, it will be still included inside every script, but it will be never mentioned inside the pdf result.

 `.md` would output a text document that would be translated to a markdown by pubsEngine.
 In this scenario, the script should output a valid markdown document to the stdout.
 We are expecting the usage of `.md` to produce some sort of table, or a dynamic paragraph.
