+.SH DESCRIPTION
+gmgeantino is a command-line utility to perform geantino scans on an
+input geometry.
+
+A "geantino" is an imaginary particle that traverses a detector,
+carrying out an inventory of material properties as it does so. The program
+produces one and two dimensional output plots in root format which can
+be examined using the root program (see root.cern.ch)
+
+.SH OPTIONS
+
+.TP
+.BI \-g \ geometry-input
+Specifies the geometry input.  The input may be a GeoModel plugin, an SQLite
+file containing a GeoModel description of a geometry, or a GDML file containing
+a GDML description of a geometry. 
+
+.TP
+.BI \-m \ macro-file
+Override the Macro file used to steer Geant4 (typically installed in /usr/share/FullSimLight) with a custom macro file. 
+
+
+.TP
+.BI \-o \ output-file
+Set the name of the output files, in root format (see root.cern.ch). The default
+output file name is geantinoMaps.root. 
+
+.TP
+.BI \-e
+Use this flag to create eta-phi radiation-interaction length 1D profile histograms
