The source code of Guile Scheme contains docstrings (e.g., https://git.savannah.gnu.org/cgit/guile.git/tree/module/srfi/srfi-43.scm#n107). In the source code of SLib I can event see comments with some keywords like @body, @example, @var, @args (https://github.com/taktoa/slib/blob/master/bytenumb.scm#L36). It seems there should be some tools to process this stuff. But I cannot find any mentions of any documentation utilities around Guile Scheme. The only thing I found is guild doc-snarf, but it is also not documented and doesn’t do anything useful with my Scheme files.
