Hi to all

great stuff explained here: http://alexott.net/en/writings/emacs-devenv/EmacsCedet.html
(thanks Alex!)

including usage like
;; enable ctags for some languages:
;;  Unix Shell, Perl, Pascal, Tcl, Fortran, Asm
(when (cedet-ectag-version-check)

however, svn version of Exuberant Ctags for --version gives like:

ctags --version

  Addresses: <dhiebert@users.sourceforge.net>, http://ctags.sourceforge.net

  Optional compiled features: +wildcards, +regex

which cannot be parsed nicely by semantic-ectags-version,

below is the patch , which hopefully should help:
