# fixchanges will take a file as input and look for text matching
# the pattern [THRIFT-nnnn] (the number of digits is not important)
# which is not a markdown link, and change it to be a markdown link.
# The tool writes to stdout so you can redirect it to a temporary
# file and then compare against the original file before replacing
# it.
#
# This tool was developed after the 0.12.0 release to assist with
# generation of CHANGES.md content.
