[ includes uuencoded executable ...tad ]
Filter copies all valid ASCII characters from the source file to the
object file. Non-ASCII characters are excluded. Carriage returns
(ASCII 13) are also excluded since a linefeed (ASCII 10) is the standard
end of line marker under AmigaDOS.
#!/bin/sh
# This is a shell archive. Remove anything before this line, then unpack
# it by saving it into a file and typing "sh file". To overwrite existing
# files, type "sh file -c". You can also feed this as standard input via
# unshar, or by typing "sh <file", e.g.. If this archive is complete, you
# will see the following message at the end:
# "End of archive 1 (of 1)."
# Contents: filter.c filter.uu
