+                          Use PaTh if PATH isn't specified in the environment
+                          when the shell starts.  A value without . in it is
+                          safest.
+                          The default value is \"/bin:/usr/bin:/sbin:/usr/sbin\".
+  --enable-shell={sh,ksh} Specify the kind of shell that is to be built (the
+                          default is sh).  Specifiying sh compiles out:
+                          command line editing (emacs/vi), history,
+                          a bunch of aliases, [[ .. ]], select, let,
+                          brace-expansion, extended globing (*(..|..), etc.),
+                          co-processes, some special environment variables
+                          (ie, MAIL, MAILCHECK, MAILPATH, RANDOM, SECONDS,
+                          TMOUT).
+  --disable-emacs         Compile out emacs command line editing (by default,
+                          this is compiled in for ksh, compiled out for sh).
+  --disable-vi            Compile out vi command line editing (by default,
+                          this is compiled in for ksh, compiled out for sh).
+  --disable-jobs          Compile out job control support.  If your system
+                          doesn't support job control, this will automatically
+			  be compiled out.
+  --disable-brace-expand  Compile out brace expansion code (a{b,c} -> ab ac)
+                          (by default, this is compiled in for ksh, compiled
+                          out for sh).  Brace expansion can also be disabled
+                          at run time (see set +o braceexpand).
+  --enable-history={no,simple,complex} By default, simple history is used for
+                          ksh, no history is used for sh.  \`simple' means
+                          history file is read on start-up, written when shell
+                          exists.  \`complex' means history files are updated
+                          after each command so concurrent shells read each
+                          other's commands.  Note: \`complex' history doesn't
+                          work well across NFS; also, it requires the mmap()
+                          and flock() functions - if these aren't available,
+                          \`simple' history is automatically used.
+  --enable-posixly-correct Enable if you want POSIX behavior by default
+                          (otherwise, posix behavior is only turned on if the
+                          environment variable POSIXLY_CORRECT is present or by
+                          using \"set -o posix\"; it can be turned off with
+                          \"set +o posix\").  See the POSIX Mode section in the
+                          man page for details on what this option affects.
+                          NOTE:  posix mode is not compatable with some bourne
+                          sh/at&t ksh scripts.
+  --enable-default-env=FILE Include FILE if ENV parameter is not set when
+                          the shell starts.  This can be useful when used with
+                          rsh(1), which creates a non-login shell (ie, profile
+                          isn't read, so there is no opertunity to set ENV).
+                          Setting ENV to null disables the inclusion of
+                          DEFAULT_ENV.  NOTE: This is a non-standard feature
+                          (ie, at&t ksh has no default environment).
+  --enable-silly          [A silly option]
+  --enable-swtch          For use with shell layers (shl(1)).  This has not
+                          been tested for some time.
