# Does two things:
# 1) modifies 'ferret_paths template' to specify locations of ferret software &
# demo data sets and places the result in the appropriate sourcing directory
# as 'ferret_paths'
# 2) installs ferret and gksm2ps executables and shared-object external functions from 
# tar file to $FER_DIR/bin
