>Description</H2
><P
>This perl script allows to determine the structural differences
    between two SGML files. It compares the files, regardless of what
    is in between the tags, to only focus on the markup. Its output
    is similar to <SPAN
CLASS="CITEREFENTRY"
><SPAN
CLASS="REFENTRYTITLE"
>diff</SPAN
>(1)</SPAN
>.</P
><P
>The typical use of <SPAN
CLASS="APPLICATION"
>sgmldiff</SPAN
> is to
    compare an SGML file with its translation into another language. 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
