writing_documentation
The way it works is very similar to Go. It's very simple: there's no need to write documentation for your code, vdoc will generate it from the source code.
Documentation for each function/type/const must be placed right before the declaration:
// clearall clears all bits in the array
fn clearall() {
}
The comment must start with the name of the definition.
An overview of the module must be placed in the first comment right after the module's name.
To generate documentation, run v doc path/to/module
(TODO this is temporarily disabled).
