# This program works as a filter that reads from stdin, copies to
# stdout *and* creates an error file that can be read by vim.
#
# This program has only been tested on SGI, Irix5.3.
#
# Written by Ives Aerts in 1996. This little program is not guaranteed
# to do (or not do) anything at all and can be freely used for
# whatever purpose you can think of.
