I find such restrictions IDIOTIC - to say the least. This piece of idiocy code
interrupted my download in the middle of mirroring some 50000+ papers,
including their .bib files. Who are you to tell me when to stop?
Now I restarted it by adding -#L9999999 - how idiotic is that? Does it mean it
have to stop at 10 million files, but 9,999,999 are OK?
I find such artificial restrictions absolutely stupid. PLEASE remove them
ASAP! I know what I am doing, I don't need you to protect me!
