Annotate files where they live.
You must have Raku installed to run this program. See this page. I use the Rakudo Star bundle, to good effect.
Run annotate.raku at the command line. You will be prompted for a directory. Within that directory, files you wish to annotate are expected along with a file called
Annotations.txt
This file's format should be:
First Line: Your Title For This Annotated Index
filename: description
filename: description
filename: description
filename: description
[etc...]
Line delimited, blank lines ignored.
A file called
index.html
will be created in the directory you specified.
