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

# Hallvard B Furuseth <h.b.furuseth@usit.uio.no>, Aug -96.
#
# Ilya Zakharevich, Oct 97: minor comments, add CPerl scan;
#   Use Hallvard's scan for XS files - since he processes the "C" part too -
#   but with a lot of improvements: now it is no worse than CPerl's one.

# Avoid builtin on OS/2:
if test ! -z "$OS2_SHELL"; then alias find=gnufind; fi

# Insure proper order (.h after .c, .xs before .c in subdirs):
# Move autogenerated less-informative files to the end:
# Hard to do embed.h and embedvar.h in one sweep:

topfiles="`echo ' ' *.y *.c *.h ' ' | sed 's/ \(embed\(var\|\)\.h\|obj\(pp\|XSUB\)\.h\|globals\.c\) \(\(embedvar\|objpp\).h \|\)/ /g'`"

## PP(pp_const)
## PERLVARI(Grsfp, PerlIO *, Nullfp)
## PERLVAR(cvcache,      HV *)

# Putting PL_\1 in the substitution line makes etags dump core
# Thus we do it later (but 20.2.92 does it OK).
