| 50 | .SH NAME |
| 51 | s2p - Sed to Perl translator |
| 52 | .SH SYNOPSIS |
| 53 | .B s2p [options] filename |
| 54 | .SH DESCRIPTION |
| 55 | .I S2p |
| 56 | takes a sed script specified on the command line (or from standard input) |
| 57 | and produces a comparable |
| 58 | .I perl |
| 59 | script on the standard output. |
| 60 | .Sh "Options" |
| 61 | Options include: |
| 62 | .TP 5 |
| 63 | .B \-D<number> |
| 64 | sets debugging flags. |
| 65 | .TP 5 |
| 66 | .B \-n |
| 67 | specifies that this sed script was always invoked with a sed -n. |
| 68 | Otherwise a switch parser is prepended to the front of the script. |
| 69 | .TP 5 |
| 70 | .B \-p |
| 71 | specifies that this sed script was never invoked with a sed -n. |
| 72 | Otherwise a switch parser is prepended to the front of the script. |
| 73 | .Sh "Considerations" |
| 74 | The perl script produced looks very sed-ish, and there may very well be |
| 75 | better ways to express what you want to do in perl. |
| 76 | For instance, s2p does not make any use of the split operator, but you might |
| 77 | want to. |
| 78 | .PP |
| 79 | The perl script you end up with may be either faster or slower than the original |
| 80 | sed script. |
| 81 | If you're only interested in speed you'll just have to try it both ways. |
| 82 | Of course, if you want to do something sed doesn't do, you have no choice. |
| 83 | .SH ENVIRONMENT |
| 84 | S2p uses no environment variables. |
