+.SH NAME
+pycamGUI \- start the graphical user interface of the \fBPyCAM\fR Toolpath Generator
+for 3-Axis CNC machining
+.SH SYNOPSIS
+.B pycamGUI
+[\fIoptions\fR] [\fISTL_input\fR [\fIGCode_output\fR]]
+.SH DESCRIPTION
+.PP
+\fBPyCAM\fR is a toolpath generator for 3-axis CNC machining. 
+.PP
+You can configure different cutter shapes and differen path strategies for preparing
+multiple passes.
+.PP
+The output of \fBPyCAM\fR is G-Code suitable for EMC2 or other machine controllers.
+.SH OPTIONS
+The following options control the behaviour of \fBPyCAM\fR:
+.TP
+\fB\-h\fR, \fB\-\-help\fR
+show the available options and exit
+.TP
+\fB\-\-gui\fR
+don't create the outputfile on the fly - just preset the output filename and show the GUI

+enable a specific processing settings template - e.g. 'Rough', 'Semi-finish' or 'Finish'
+(requires the GTK interface)
+.TP
+\fB\-\-disable-ode\fR
+disable experimental ODE collision detection
+.SH ENVIRONMENT VARIABLES
+.IP PYCAM_DATA_DIR
+Override the default location of the GTK interface definition files.
