# usage:  gdirs [-fF]

#  gdirs -f cd's both terminal and finder to chosen directory
#  gdirs -F cd's only the Finder to the chosen directory
#  gdirs with no argument changes only the terminal directory

# modified by Marc Baaden to get the directory list from a file rather
# than from an environment variable. This was done in order to make
# gdirs independent from the actual shell used.
