+/*
+ * view.c -- a silly little viewer program
+ *
+ * written by Eric S. Raymond <esr@snark.thyrsus.com> December 1994
+ * to test the scrolling code in ncurses.
+ *
+ * modified by Thomas Dickey <dickey@clark.net> July 1995 to demonstrate
+ * the use of 'resizeterm()', and May 2000 to illustrate wide-character
+ * handling.
+ *
+ * Takes a filename argument.  It's a simple file-viewer with various
+ * scroll-up and scroll-down commands.
+ *
+ * n	-- scroll one line forward
+ * p	-- scroll one line back
+ *
+ * Either command accepts a numeric prefix interpreted as a repeat count.
+ * Thus, typing `5n' should scroll forward 5 lines in the file.
+ *
+ * The way you can tell this is working OK is that, in the trace file,
+ * there should be one scroll operation plus a small number of line
+ * updates, as opposed to a whole-page update.  This means the physical
+ * scroll operation worked, and the refresh() code only had to do a
+ * partial repaint.
