.SH DESCRIPTION
\fBprepair\fR permits you to easily repair "broken" GIS
polygons, and that according to the international standards ISO 19107.
In brief, given a polygon stored in WKT, it automatically repairs it
and gives you back a valid WKT.
Automated repair methods can be considered as interpreting ambiguous or
ill-defined polygons and giving a coherent and clearly defined output.
.SH OPTIONS
.TP 
\*(T<\fB\-\-wkt\fR\*(T> \fI'POLYGON(0 0, 1 0, 1 1, 0 0)'\fR
Process polygon from WKT string
.TP 
\*(T<\fB\-f\fR\*(T> \fIinfile.txt\fR
Process polygon from WKT string on the first line of the file
.TP 
\*(T<\fB\-\-ogr\fR\*(T> \fIinfile.shp\fR
Process first polygon of the input file
.TP 
\*(T<\fB\-\-robustness\fR\*(T>
Compute the robustness of the input/output
.TP 
\*(T<\fB\-\-setdiff\fR\*(T>
Uses the point set topology paradigm (default: odd-even paradigm)
.TP 
\*(T<\fB\-\-minarea\fR\*(T> \fIAREA\fR

.TP 
\*(T<\fB\-\-shpOut\fR\*(T>
