If the translation was done cleanly, <SPAN CLASS="APPLICATION" >sgmldiff</SPAN > returns without finding any difference in the markup.</P ><P >An example of a typical call to sgmldiff is:</P ><PRE CLASS="SCREEN" > sgmldiff english.sgml italiano.sgml </PRE ><P >If there are differences in markup between both files, <SPAN CLASS="APPLICATION" >sgmldiff</SPAN > will output a series of differences reports summarized with lines of the form: <P ></P ><DIV CLASS="VARIABLELIST" ><DL ><DT >169a164</DT ><DD ><P >At line 169 of the first file, line 164 of the second file has been added.</P ></DD ><DT >8a12,15</DT ><DD ><P >At line 8 of the first file, lines 12 to 15 of the second file have been added.</P ></DD ><DT >41d28</DT ><DD ><P >Line 41 of the first file has been destroyed, to obtain line 28 of the second file.</P ></DD ><DT >63,66d61</DT ><DD ><P >Lines 63 to 66 of the first file have been destroyed. to obtain line 61 of the second file.</P ></DD ><DT >52c51</DT ><DD ><P >Line 52 of the first file has been changed into line 51 of the second file.</P ></DD ><DT >5,7c8,10</DT ><DD ><P >Lines 5 to 7 of the first file have been changed into lines 8 to 10 of the second line.</P ></DD ></DL ></DIV > In addition to those summaries, the lines of the first file are shown preceeded by '<' and the lines of the second file are shown preceeded by '>".</P ></DIV ><DIV CLASS="REFSECT1" ><A NAME="AEN1123" ></A ><H2 >Options</H2 ><P >Here is the list of actions that can be requested to sgmldiff:</P ><DIV CLASS="GLOSSLIST" ><DL ><DT ><B > <P >[<CODE CLASS="OPTION" >-a</CODE > | <CODE CLASS="OPTION" >--attributes</CODE >]</P > </B ></DT ><DD ><P >Include the attribute values in the difference tests.
