+ * 'impv' impress (i.e. canon) previewer for a SUN workstation.
+ * impv [-p##] [-s] [job# | -n name]
+ * where job# is the job number of the troff/dimp processed output suitable
+ * for the canon imagen printer. This can be found by executing 'ipq'. The
+ * -p## argument sets the number of pages the user will be allowed to
+ * backup. The -n name option will cause the users most recent job to
+ * be displayed.The human interface for this proram leaves something to be
+ * desired ( skip pages, print page number 'n', etc.).
+ * The algorithm for crunching glyphs could be improved from the straight
+ * forward method used.
+#ifdef COLOR
+ * The -s option will cause the output to be sent to the color monitor. Troff
+ * Macros .CC and .BG set the background and current color. This option is
+ * intended for slide production.
+#endif COLOR
+ *
+ * This program requires that a 'file server' (used very loosely)
+ * exist on the remote host UNIX system. See the code for impvserv.
