# This is a perl script for editing your source files that were
# written with ctemplate <0.95, to use the new #include paths,
# namespace names, and function locations in ctemplate 0.95.
#
# This script will modify your files in place. It is safe to
# call it multiple times. To call it, do something like:
# find <root of my project tree> -print0 | xargs -0 ./convert_to_95.pl
#
# Issues:
# TemplateFromString logic is tricky. Best to check up by hand.
# Can't always tell when 1st arg to TemplateFromString is empty string.
# If it might be for your app, change the logic to use StringToTemplate.
# Fails if TemplateFromString or StringToTemplate span multiple lines.
# Change all the #include lines
