# Written January 1996 by Rick Jansen (rick@sara.nl)
# URL: http://www.sara.nl/rick
# usage: treesed pattern1 pattern2 -tree
# treesed pattern1 pattern2 -files file1 file2 ...
# example: treesed href HREF -files *.html
# Treesed searches for pattern1 and replaces pattern1 by pattern2
# if pattern2 supplied. If only pattern1 given treesed just searches.
# Treesed will search in all files and subdirectories of the current
# directory
