Makespec makes use of several plugins of Pandoc Markdown syntax.
One can include markdown files with the following syntax:
`filename.md`{.include}
The inclusion statement should be placed on the begin of a single line. By now, inclusion is implemented on syntax level. A later version of this plugin will act on the abstract syntax tree.
To include a file as code block use the following syntax:
`filename.json`{.include .codeblock .json}
