Most languages have two concepts of comments: single-line and multi-line. Budgie supports both.
Single Line Comments
Use the comment line command. It takes in any number of parameters and directly outputs them.
comment line : Hello world!
In C#: // Hello world!
In Python: # Hello world!
Multi Line Comments
Also known as "block" comments, these are preceded by comment block start and ended with comment block end. Each line of actual block content comes from comment block, which, like comment line, directly prints all its parameters.
