[GRASSLIST:2666] RE: [GRASSLIST:2639] couldn´t execute "v.trim": no such file or directory

Try v.rm.dangles

I wanted to use v.trim but the command wasn´t found. But the manual
exists, so why can´t I use this modul?
I am using GRASS 5.0.2 Binaries from April 2003

Any idea? What can I use instead?
