# To use a different version of emacs, set the EMACS environment
# variable before running.
# After running, update those files mentioned in $byhand by hand.
# Always review the output of this script before committing it!
# A useful command to review the output is:
# filterdiff -x \*.c -x \*.cc -x \*.h -x \*.exp updates.diff
# This removes the bulk of the changes which are most likely
# to be correct.
####
# Configuration
####
# As of Emacs 22.0 (snapshot), wrapping and copyright updating do not
# handle these file types - all reasonable:
# Assembly (weird comment characters, e.g. "!"); .S usually has C
# comments, which are fine)
# Fortran ("c" comment character)
# igen
# Autoconf input (dnl)
# texinfo (@c)
# tex (%)
# *.defs as C
# man
# So these need to be done by hand, as needed
