261 # substitutions, '$((...))' for shell arithmetic, and support for
262 # '${var#...}' and '${var%...}' parameter expansions).
264 # We require that the shell can correctly trap EXIT when 'set -e' is in

267 # We want to able to define shell aliases with the same name of shell
270 # We also prefer shells that, when 'set -x' is in effect, do not also
271 # redirect traces upon stderr redirections. For example,
272 # $ set -x; echo x 2>file
273 # would emit "+ echo x" into file with older zsh versions. Similarly,
274 # $ set -x; P=1 true 2>file
275 # would emit "P=1" into file with /usr/xpg4/bin/sh from Solaris 10 and
276 # /bin/sh from SunOS 5.11 and OpenBSD 4.7.
278 # Finally, we look for weird bugs and portability problems mentioned in
279 # the Autoconf manual, and reject shells that suffers from them. (TODO)
281 # Use '$am_score' to indicate the degree of acceptability of the shell.
282 # A score of "10" means that the shell is good enough for our needs;
283 # a score of "9" means that the shell has some minor bugs or limitation,
