# samba-print-pdf
# This is a script which allows you to set up a virtual printer on samba
# which will take the file (generated by a postscript filter on windows)
# and turn it into a PDF, informing the user of where it is when it
# is done

# Arguments:
# $1 = file (usually passed with %s from samba)
# $2 = unix prefix to where to place the file (~%u should work)
# $3 = windows prefix to the same location (\\%L\%u should work)
# $4 = user/computer to send a notification to (%u or %m)
# $5 = IP address of client (%I)
