Please find instructions on how to apply the new license at

I've been using the attached relicense.pl rather than the python script in
the committers directory, because it preserves the copyright years. It does
even more, adding the year 2004 automatically.
Questions:
- Does anyone already have a forrested version of LICENSE.txt?
- Does anyone already have a Docbook version of LICENSE.txt?

# This file takes as input a directory of source files.
# It scans the directory for files matching the regular
# expression $searchRe. In fact this means, that the
# file must contain a line beginning with
#
#" * The Apache Software License, Version 1.1"
#
# followed by another line ending with
#
#"SUCH DAMAGE."
#
# If such a pattern is detected and it contains a copyright year
# (like 2003, or 2002-2003, or 2001, 2003), then the pattern is
# replaces with the string $NEW_LICENSE, indented by " * ".
# In other words, it handles C or Java style comments.
#
# The script updates the copyright year in the following sense:
# - If the year 2004 is already included, the year is copied
#verbatimly.
# - If the year 2004 is not yet included, but ends with
#",2003", then the string "-2004" is included.
# - Otherwise the year is copied and the string ",2004" is
#appended.
