18 Creates a <B>dgt</B> file with lines which delimit different classes in input
19 <B>epp file.</B> If <B>-l</B> option given, puts a label point into each closed polygon.
21 Default output filename is constructed from name of input file, by replacing
22 suffix <I>.epp</I> by <I>.dgt</I> . <P>
23 Lines can be created "staircase"-like or smooth. Smoothing
24 is controlled by <B>tolerance </B> factor, which defines maximum size of line
25 segment, which can be changed. <P>

40 <DD>Display progress indication. Useful on large files, but significantly
41 decreases performans on small ones. </DD>
43 <DT><B>-m, --margins</B> </DT>
44 <DD>Controls behavouir on file
45 edges. By default <B>border</B> treats all areas outside file as <I>offsite,</I> but
46 when this option given, it assumes that all classes at the file edge are
47 continued outside it. </DD>
49 <DT><B>-t --tolerance</B> </DT>
50 <DD>Defines tolerance value. Default is zero
51 -- no smoothing. </DD>
53 <DT><B>-o --output-file</B> </DT>
54 <DD>Allows to specify output file name explicitly.
