I am not sure if this is good way to check if ctags supports "-e" or not. + then ctags --version 2>&1 | grep -- -e >/dev/null Perhaps, "--help" might be intended rather than "--version" to check supported options? Even so, ctags would have other option whose name contains "-e" than Emacs support, so this check could end in a wrong result. Therefore, it seems to me that it is better to check immediately if etags is available in case that we don't have Exuberant-type ctags.
