# In order to easily access many of the installed SCO Skunkware 
# components, you may wish to add /usr/local/bin to your PATH,
# /usr/local/man to your MANPATH and /usr/local/java to your CLASSPATH. 
# For instance, a Bourne shell user could add the following to their 
# $HOME/.profile :
# 
#         PATH=$PATH:/usr/local/bin
#         MANPATH=$MANPATH:/usr/local/man
#         if [ "$CLASSPATH" = "" ] ; then

#         fi
#         CLASSPATH=$CLASSPATH:/usr/local/java
#         export PATH MANPATH CLASSPATH
# 
# The system administrator can set these on a system-wide basis by
# modifying the files /etc/profile, /etc/default/login and /etc/default/man.
