.SH NAME
LeoCAD \- CAD program for LEGO models.
.SH SYNOPSIS
\fIleocad \fR[\fIOPTIONS\fR] [\fIINFILE\fR]
.SH "DESCRIPTION"
\fILeoCAD \fR is a CAD program for creating virtual LEGO models. It
has an easy to use interface and includes thousands of different
parts in its library.

.SH OPTIONS
Below is a summary of all of the options that \fILeoCAD\fR
accepts. Many options have two equivalent names, one of
which is a single letter preceded by -, and the other of
which is a long name preceded by --. Brackets ([ and ])
indicate that an option takes an optional parameter.

.TP
.B infile
Loads the project file \fIinfile\fR

.br
Saves a picture to \fIoutfile.ext \fR in the image format specified
by \fIext\fR and exits. If outfile is not given then the program will
use a name based on \fIinfile\fR. The file format is selected by \fIext\fR
and can be gif, bmp, png or jpg (if \fIext\fR is not present then the
default preferences format will be used).

.br
Sets the height of the picture to \fIheight\fR.

.TP
\fB\-f \fItime\fR, \fB\-\-from \fItime
.br
Start saving pictures at the step \fItime\fR. Steps start at 1.

.TP

.br
Save pictures until the step \fItime\fR.

.TP

.br
Sets the active camera to \fIcamera\fR.

.TP
\fB\-ss \fIid\fR,\ \fB\-\-stud\-style\ \fIid
.br
