Overview

Reads settings.file_order line by line, evaluates whether the line is an “import” statement and appends the result to a temporary file. A header containing all of the necessary imports is then compiled with the contents in the tmp file.

The compiler should never load a file into memory in its entirety, the file should instead be read line by line as to save memory. This process is certainly slower, however, it is a good compromise, especially when loading large files.
