# ObExcuse: This is my first perl script

#
# To use the script, make a subdirectory and save (or symlink)
# it there. This will be the script data directory.
# Adjust the path to your napshare temporary directory,
# any file not blacklisted and existing in that directory will be
# downloaded.
#
# While used as a filter, the filenames are normalized, matched
# against some filters and, depending on the result, written to
# 1.txt (new), 2.txt or 3.txt (different blocklists) as long as
# they are neither in f_getlist or f_blocklist.
#
# to download, move a line from 1.txt to f_getlist.
# to never display a line again, move it to f_blocklist.
# (if the filter is still active, rename the .txt-file first).
