21 # Usage: cd src/gdb && sh ./copyright.sh
22 # To use a different version of emacs, set the EMACS environment
23 # variable before running.
25 # After running, update those files mentioned in $byhand by hand.
26 # Always review the output of this script before committing it!
27 # A useful command to review the output is:
28 # filterdiff -x \*.c -x \*.cc -x \*.h -x \*.exp updates.diff
29 # This removes the bulk of the changes which are most likely
36 # As of Emacs 22.0 (snapshot), wrapping and copyright updating do not
37 # handle these file types - all reasonable:
38 # Assembly (weird comment characters, e.g. "!"); .S usually has C
39 # comments, which are fine)
40 # Fortran ("c" comment character)
42 # Autoconf input (dnl)
47 # So these need to be done by hand, as needed
61 # Files which should not be modified, either because they are
62 # generated, non-FSF, or otherwise special (e.g. license text,
63 # or test cases which must be sensitive to line numbering).
88 # Disable filename expansion, so that we can get at the glob patterns
