#!/bin/sh# This file illustrates how to generate a useful TAGS file via etags# for emacs.  This should be invoked from the top source directory i.e.:#   > build/MakeEtags# and will create a TAGS file in the top source directory.# This script falls under the Apache License.# See http://www.apache.org/docs/LICENSE# Once you have created ./TAGS in emacs you'll need to setup# tag-table-alist with an entry to assure it finds the single ./TAGS# file from the many source directories.  Something along these lines:# (setq tag-table-alist#	'(("/home/me/work/httpd-2.0/" #	   . "/home/me/work/httpd-2.0/")#	 ))# This requires a special version of etags, i.e. the# one called "Exuberant ctags" available at:#    http://fly.hiwaay.net/~darren/ctags/# Once that is setup you'll need to point to the# executable here:etags=~/local/bin/etags# Exuberant etags is necessary since it can ignore some defined symbols# that obscure the function signatures.ignore=AP_DECLARE,AP_DECLARE_NONSTD,__declspec# Create an etags file at the root of the source# tree, then create symbol links to it from each# directory in the source tree.  By passing etags# absolute pathnames we get a tag file that is# NOT portable when we move the directory tree.find . -name '*.[ch]' -print | $etags -I "$ignore"  -L -
