+.. class:: infomark
+
+This tool generates the cavity definition for rDock docking (the receptor.as file) using the rbcavity program.
+See http://rdock.sourceforge.net/ for more details about rDock and associated programs.
+Only a subset of the parameters are currently exposed. Read the rDock docs for a full understanding.
+
+-----
+
+.. class:: infomark
+
+**Inputs**
+
+1. The protein receptor to dock into as a file in Mol2 format.
+2. A reference ligand used to define the location of the active site in Molfile or SDF format.
+3. Various parameters for the mapper and cavity generation. Sensible defaults are provided for all.
+
+-----
+
+.. class:: infomark
+
+**Outputs**
+
+An active site definition binary file (receptor.as) that is needed by the rDock docking program to guide the docking.
