+
+twill-refsort - Sort mini-indexes alphabetically
+
+=head1 SHORT DESCRIPTION
+
+This small Perl script 'twill-refsort' sorts the mini-indexes for each section
+in the '.ref' file created by 'twill foo' (twice) and 'tex foo' (first run).
+It reads its input from STDIN and writes its output to STDOUT.
+
+=over
+
+=item Run TWILL twice on your 'foo'.w, creating 'foo'.tex
+
+=item Invoke "tex 'foo'.tex", creating 'foo'.ref
+
+=item Invoke "twill-refsort < 'foo'.ref > 'foo'.sref"
+
+=item Run TeX on 'foo'.tex a second time
+
+=back
+
+See also "man twill" for more information on how to use the TWILL system.
