6 | | -(An `x' indicates that some progress has been made, but that the feature is |
7 | | -not complete yet.) |
| 6 | +With the 3.0 release, we are acknowledging that awk is not PERL, nor should |
| 7 | +it become PERL. (To paraphrase Dennis Ritchie, "If you want PERL, you |
| 8 | +know where to get it.") |

| 10 | +The focus on the future is thus narrowed to performance and functional |
| 11 | +enhancements, with only minor plans for significant new features. |
