+Busybox POSIX conformance table
+
+See POSIX documentation (1003.1-2008) here:
+http://www.opengroup.org/onlinepubs/9699919799/
+And the complete list of all utilities that POSIX covers:
+http://www.opengroup.org/onlinepubs/9699919799/utilities/utilities.html
+
+This listing is a work in progress, and currently only covers
+tool options (not operands, enviroment variables, return codes, etc..).
+For each option it is set if it (a) exists and (b) compliant to POSIX 2008.
+Some options exist but there is no value in the 'compliant' column: that
+means no one has yet bothered to make sure that the option does what it is
+required to do.
