# Check if the given shell is good enough to run our test scripts.
# Inspired to gnulib's 'tests/init.sh'.
#
# We require POSIX and XSI features (e.g., '$(...)' for command
# substitutions, '$((...))' for shell arithmetic, and support for
# '${var#...}' and '${var%...}' parameter expansions).
#
# We require that the shell can correctly trap EXIT when 'set -e' is in
# effect (OSF1/Tru64 sh failed to do so, see commit v1.10b-52-g9fe8259).
#
# We also prefer shells that, when 'set -x' is in effect, do not also
# redirect traces upon stderr redirections. For example,
# $ set -x; echo x 2>file
# would emit "+ echo x" into file with older zsh versions. Similarly,
# $ set -x; P=1 true 2>file
# would emit "P=1" into file with /usr/xpg4/bin/sh from Solaris 10 and
# /bin/sh from SunOS 5.11 and OpenBSD 4.7.
#
# Finally, we look for weird bugs and portability problems mentioned in
# the Autoconf manual, and reject shells that suffers from them. (TODO)
#
# Use '$am_score' to indicate the degree of acceptability of the shell.
# A score of "10" means that the shell is good enough for our needs;
# a score of "9" means that the shell has some minor bugs or limitation,
# but is still (barely) acceptable for our uses. Any other score means
# that the shell is broken or unfit.
