+     "The main janitor functions can: perfectly format @code{data.frame column}
+names; provide quick counts of variable combinations (i.e., frequency tables
+and crosstabs); and isolate duplicate records.  Other janitor functions nicely
+format the tabulation results.  These tabulate-and-report functions
+approximate popular features of SPSS and Excel.  This package follows the
+principles of the \"tidyverse\" and works well with the pipe function
+@code{%>%}.  janitor was built with beginning-to-intermediate R users in mind
+and is optimized for user-friendliness.  Advanced R users can already do
+everything covered here, but with janitor they can do it faster and save their
+thinking for the fun stuff.")
