#  Last revision April 24, 2002. Slight change for directories with and 
#  without trailing slash, made by Vince.

#### 
# IMPORTANT: Change HOME to where you want the script to be created.
# If you're unfamiliar with the syntax, just comment out the line below
# (by putting a # in front of it) and add a line below that which says
# "HOME=/path/you/want/to/use" (no quotes though.) Make sure that this
# path does NOT end with a slash.

test $1 && HOME=$1
