Hello Ricardo, thank you for your replies.

Actually, nearly every synopsis and description in these patches are
taken verbatim from CRAN.

I'm not familiar enough with this package to amend the description
provided by the author, so I replaced it with the one offered in the
package's GitHub repository.

Upper-case characters corrected.

New patch attached.
