New tool for textutils

Recently i needed a tool for removing from a text file the lines longer 
or shorter than certain limits, and i couldn't find one in the textutils 
package.
So i have written a program named "sieve" to do that.
The output of "sieve --help" is:

------------------ BEGIN OF OUTPUT -------------------

Usage: sieve [options] [file]
remove lines of given length from file or standard input,
writing to standard output.
Options:
  -h, --help               display this help and exit
  -V, --version            output version information and exit
  -M, --max-length=<n>     remove lines longer than <n>
  -m, --min-length=<n>     remove lines shorter than <n>
  -o <file>                place the output into <file>

Report bugs to <ant_diaz@xxxxxxxxxxx>.

------------------ END OF OUTPUT -------------------

If you think this program is useful enough to include in the coreutils 
package, please tell me. I'll send you the code, give copyright to the 
FSF, change the name of the program if necessary, etc.

Regards.
