| 22 | # To use a different version of emacs, set the EMACS environment |
| 23 | # variable before running. |
| 24 | |
| 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 |
| 30 | # to be correct. |

| 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) |
| 41 | # igen |
| 42 | # Autoconf input (dnl) |
| 43 | # texinfo (@c) |
| 44 | # tex (%) |
| 45 | # *.defs as C |
| 46 | # man |
| 47 | # So these need to be done either by hand, as needed, or by the copyright.py |
| 48 | # script. |
