# 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
