+      This package also provides extensive support for antiviral agents, even though it is not the primary
+      scope of this package. Working with data containing information about antiviral drugs was never easier.
+      Use these functions to get valid properties of antiviral drugs from any input or to clean your input.
+      You can even retrieve drug names and doses from clinical text records, using `av_from_text()`.
