This <a href="mass_prop.sh">script</a> loads a board file and a
<a href="example.tab">tab</a> file then interprets each line of the tab
as instructions to search for objects and edit them.
<p>
The columns of the table are separated by semicolon. The first column is
a <a href="../query_examples">query() expression.</a> Further columns
are <i>name=value</i> pairs for propset(). To set an attribute in propset syntax,
<i>name</i> needs to be prefixed with "a/".
