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