Nzb validation before download on linux

[ulthar]

I want to check that all files exist on my newsserver before I start to download anything. I found some windows program for this on google (nzb validator), but I need a program for linux. Are there any linux programs for this?

I don't have much use for my Windows program, since I rarely have to repair anything.

Also, validation results from Astraweb are inaccurate.
