ctags/etags: rc file?

[Alfred M. Szmidt]

Would it be possible for ctags/etags to read a simple .etags (or
something) file that contains the command line arguments?  The reason
for it is that often projects have a bunch of default arguments that
are being passed to etags, which are not just regexps and it is
annoying to keep track of them at times.

If .etags (one argument per line) contains,

  --language=none
  --regex='/[ \t]*function.*=[ \t]*\([^ \t]*\)[ \t]*(/\1/'
  --regex='/###key \(.*\)/\1/'
  --regex='/[ \t]*global[ \t].*/'
  *.m

And then issuing "etags -Z" (or some other sensible short option) it
would be equivalent to running,

  etags --language=none --regex='/[ \t]*function.*=[ \t]*\([^ \t]*\)[ 
\t]*(/\1/' --regex='/###key \(.*\)/\1/' --regex='/[ \t]*global[ \t].*/' *.m
