+The main tools are:
+
+@enumerate
+@item @code{g:GOSt}, functional enrichment analysis and visualization of gene
+  lists;
+@item @code{g:Convert}, gene/protein/transcript identifier conversion across
+  various namespaces;
+@item @code{g:Orth}, orthology search across species;
+@item @code{g:SNPense}, mapping SNP rs identifiers to chromosome positions,
+  genes and variant effects.
+@end enumerate
+
+This package is an R interface corresponding to the 2019 update of
+@code{g:Profiler} and provides access to versions @code{e94_eg41_p11} and
