less, a paginator

[Jim Scardelis]

> This is a pagination program similar to more or pg.
> It has been run on 4.1BSD, 4.2BSD and System V, 
> but has not been tested on any other system.
> To install, delete everything down to the cut line below, 
> put the file in an empty directory, and run sh on the file.
> Then read the file called INSTALLATION.
> Problems, complaints, praise to the author.

Attached is a shar archive containing a diff file "screen.diff" to be
applied to screen.c, and "makefile.xen" for compiling less under
Xenix 3.0 on an IBM PC/AT.



# This is a shell archive.  Remove anything before this line,
# then unpack it by saving it in a file and typing "sh file".

# Makefile for "less"
#
# Invoked as:
#	make all
#   or	make install
# Plain "make" is equivalent to "make all".
#
# If you add or delete functions, remake funcs.h by doing:
#	make newfuncs
# This depends on the coding convention of function headers looking like:
#	" \t public <function-type> \n <function-name> ( ... ) "
#
# Also provided:
#	make lint	# Runs "lint" on all the sources.
#	make clean	# Removes "less" and the .o files.
#	make clobber	# Pretty much the same as make "clean".
