1 | # Make a TAGS file for emacs ``M-x find-tag'' from all <c,h,y,xs> source files. |
2 | # (``make realclean'' first to avoid generated files, or ``make'' first |
3 | # to get tags from all files.) |
4 | # |
5 | # (IZ: to be a happier jumper: install 'imenu-go.el' from |
6 | # ftp://ftp.math.ohio-state.edu/pub/users/ilya/emacs.) |
7 | # |
8 | # (Some tags should probably live in their own subdirs, like those in x2p/, |
9 | # but I have never been interested in x2p anyway.) |

13 | # Ilya Zakharevich, Oct 97: minor comments, add CPerl scan; |
14 | # Use Hallvard's scan for XS files - since he processes the "C" part too - |
15 | # but with a lot of improvements: now it is no worse than CPerl's one. |
