The documentation in the About window is supplied at the top of the files when reapack-index is used (
like this).
The display name (aka "description") of the package as it appears in the browser is also specified by the author. It is just an alias to have a cleaner list, it doesn't affect the actual file names (though they should both be similar).
All packages, whether they have one or many files in them (like spk77's "Set solo for send X" which is made of 6 lua files), are listed as one unique entry when ReaPack uses the word "package".
