# Usage: cd src/gdb && sh ./copyright.sh

# 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
