path

:
#  A shell script displays various IPW paths, i.e., lists of directories.
#  The script is invoked as
#
#	{script} [ -s ] ( user | system | man )
#
#  The argument specifies which path to display:
#
#	user	= directories with IPW user commands
#	system	= directories with IPW system commands
#		    (for software administration and development)
#	man	= directories with IPW man pages
#
#  The directories in the list are separated by colons.  If the -s option
#  is specified, the directories are separated by spaces.
#
#  Note:  This script requires that the environment variable IPW be set.
#
#  This script is usually invoked in a user's .cshrc or .profile file to
#  establish IPW paths.  For example, suppose a person is using the C shell.
#  If her .cshrc file has these two lines:
#
#	set path=($path -s `$IPW/path user`)
#	setenv MANPATH /usr/man:`$IPW/path man`
#
#  then the directories with IPW user commands are added to the shell's
#  search path for executables, and the IPW "man" directories will be
#  searched by the "man" command.
