-# cdhist - cd replacement with a directory stack like pushd/popd
-#
-# usage: cd [-l] [-n] [-] [dir]
-#
-# options:
-#	-l	print the cd directory stack, one entry per line
-#	-	equivalent to $OLDPWD
-#	-n	cd to nth directory in cd directory stack
-#	-s	cd to first directory in stack matching (substring) `s'
-#
-# arguments:
-#	dir	cd to dir and push dir onto the cd directory stack
-#
-# If the new directory is a directory in the stack and the options selected
-# it (-n, -s), the new working directory is printed
-#
-# If the variable CDHISTFILE is set, the cd directory stack is loaded from
-# and written to $CDHISTFILE every time `cd' is executed.
-#
-# Note: I got this off the net somewhere; I don't know the original author
