+#
+# 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 want to able to define shell aliases with the same name of shell
+# builtins.
+#
+# 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.
