4: * 'impv' impress (i.e. canon) previewer for a SUN workstation.
5: * impv [-p##] [-s] [job# | -n name]
6: * where job# is the job number of the troff/dimp processed output suitable
7: * for the canon imagen printer. This can be found by executing 'ipq'. The
8: * -p## argument sets the number of pages the user will be allowed to
9: * backup. The -n name option will cause the users most recent job to
10: * be displayed.The human interface for this proram leaves something to be
11: * desired ( skip pages, print page number 'n', etc.).
12: * The algorithm for crunching glyphs could be improved from the straight
13: * forward method used.
14: #ifdef COLOR
15: * The -s option will cause the output to be sent to the color monitor. Troff
16: * Macros .CC and .BG set the background and current color. This option is
17: * intended for slide production.
18: #endif COLOR
19: *
20: * This program requires that a 'file server' (used very loosely)
21: * exist on the remote host UNIX system. See the code for impvserv.
