+# Usage: gp-ext-imp [options] [<input-file>] [<output-file>]
+#
+# A small script to produce half-useful bar graphs from the PostScript
+# output produced by gnuplot.  
+# Translation is done in the X axis automatically, and should
+# be `good enough' for graphs with smallish numbers of bars.
+#
+# Original version:          Bryan O'Sullivan <bos@dcs.glasgow.ac.uk> 09.94
+# New and improved version:  Hans Wolfgang Loidl <hwloidl@dcs.glasgow.ac.uk>
+#
+# Options:
+#  -w <width>      ... width of vertical bars
+#  -g <gray-level> ... set gray-level (between 0 and 1; 0 means black)
+#  -m <move>       ... move the graph <move> pixels to the right
+#  -h              ... help; print this text
+#  -v              ... verbose mode
