This program provides an easy way to create a message reporting a bug
in parrot, and e-mail it to the parrot developers.
It is *NOT* intended for:
- sending test messages,
- or reporting bugs in languages targetting parrot,
- or reporting bugs in some library bindings for parrot,
- or simply verifying that parrot works.
It is *ONLY* a mean of reporting verifiable problems with the core
parrot distribution, and any solutions to such problems, to parrot
developers.
If you're just looking for help with parrot, subscribe to the parrot
mailing list, parrot-porters<at>perl.org.
