.sh NAME
pg \*- page a file on a display terminal
.sh SYNOPSIS
pg [name]
.sh DESCRIPTION
.it Pg
allows the user to page through a file on a display terminal.
On display commands
.it pg
shows one page of the file. The size of the page can be set by
the user, the default value is 22.
The user can establish a "print" file, where he may write pages
of the file.
Using the "p" command the user creates a file; every page that gets looked
at is then also put on that file. This feature can dynamically turned on and
off.
.it Pg
has  a notion of the "current" line. This current line is changed by display
commands.
.br
The page "around" the current line is displayed. The page offset
determines the number of lines displayed before the current line.
When no file-name is given, it uses the standard input. This makes it
usable as a filter.
.br
^ and $ may be used in search-strings for beginning and end of line.
.br
Commands allowed are the following:
.br
display commands:
.br
	<num>	set current line to <num>
.br
	$	set current line to the end of the file
.br
	.	do not change the current line
.br
	+	increment the current line by one page.
.br
	-	decrement the current line by one page
.br
	+<num>	increment the current line by <num>
.br
	-<num>	decrement the current line by <num>
.br
	/str/	set current line to next occurrence of "str"
.br
	//	same as above, use last given string
.br
miscellaneous commands:
.br
	r<num>	set page offset to <num>.
.br
	s<num>	set page size to <num>
.br
.in +16
.ti -16
	p file	create a printfile named "file" and start copying the output to that file.
.in -16
.br
	p+	turn printing on the printfile on
.br

Error messages are self-explanatory.
