+NAME
+====
+
+adjust_detector - move detector panels
+
+
+SYNOPSIS
+========
+
+adjust_detector -g _input.geom_ -o _output.geom_ -p _group_ [_movement_]
+
+
+DESCRIPTION
+===========
+
+**adjust_detector** moves a panel (or group of panels) in a CrystFEL detector
+geometry file, and writes an updated geometry file.
+
+To rotate a panel, use one of **--rotx**, **--roty** or **--rotz**.  The
+rotation will be in degrees, clockwise when looking along the specified axis.
+The center of rotation will be the centroid of the corners of the panel, or the
+centroid of all the panel centers in the specified group.
+
+To translate a panel or group, use one of **--shiftx**, **--shifty** or
+**--shiftz**.  The translation will be along the positive direction of the
+specified axis.  The units are pixels, unless you additionall specify
+**--mm**.
+
+You can use multiple movements together, but the results are unspecified if you
+combine a rotation with any other movement.
+
+
+OPTIONS
+=======
+
+**-g** _input.geom_
+: Specify the input geometry filename.
+
+**-o** _output.geom_
+: Specify the output geometry filename.
+: Note that the geometry file will be re-written, meaning that any formatting
+: and comments will be lost.
+
+**-p** _group_
+: Specify the panel, or panel group, to move.
+
+**--mm**
+: Interpret panel shifts as millimetres, not pixels.
+
+**--shiftx=***n*, **--shifty=***n*, **--shiftz=***n*
+: Shift the chosen panel (or group) by _n_ along the given direction, in units
+: of pixels (unless **--mm** is used).  When moving a group of panels, the
+: pixel size of the *first* panel will be used.
+
+**--rotx=***n*, **--roty=***n*, **--rotz=***n*
+: Shift the chosen panel (or group) by _n_ degrees clockwise about the given
+: axis.  The center of rotation will be the centroid of the corners of the
+: panel, or the centroid of all the panel centers in the specified group.
