# Edit the following setting of MOUNTPT to be wherever you have
# mounted the SCO Skunkware 97 CD-ROM. By default, i have set it
# to /mnt. If you mounted the SCO Skunkware 97 CD-ROM on /usr/skunk97,
# then you would set MOUNTPT=/usr/skunk97

MOUNTPT=/mnt

# ------------------------------------------------------------------
#
# In order to easily access many of the installed SCO Skunkware 97
# components, you may wish to add /usr/local/bin to your PATH and
# /usr/local/man to your MANPATH. For instance, a Bourne shell user
# could add the following to their $HOME/.profile :
# 
#         PATH=$PATH:/usr/local/bin
#         MANPATH=$MANPATH:/usr/local/man
#         export PATH MANPATH
# 
# The system administrator can set these on a system-wide basis by
# modifying the files /etc/default/login and /etc/default/man.
