To use KnowledgeMan, edit the PATH statement in your .login file to 
include $kmanbindir :
for example, if your PATH statement looks like:

        set path = (. /usr/ucb /bin /usr/bin)

alter it to read

        set path = (. /usr/ucb /bin /usr/bin $kmanbindir )

The Environment variable KMANHOME also needs to be set to
$kmanhomedir to do this you should also 
add to your .login the statement:

	setenv KMANHOME $kmanhomedir

After you have edited .login, enter the command

        source .login

to set KMANHOME and to execute the new path statement.  


To start KnowledgeMan on a workstation

	in sunview environment, enter
        kmanstool

	in openwin environment, enter
        kmanxtool

To start KnowledgeMan on a terminal, enter
