[Geiser-users] Calling `tar' with `sudo'

[Diogo F. S. Ramos]

The following files and line references

  ./README:54
  ./INSTALL:61
  ./doc/install.texi:87
  ./README.elpa:47

have the following command

  curl http://3e8.org/pub/chicken-doc/chicken-doc-repo.tgz | sudo tar zx

Is it necessary to call `tar' with `sudo'?
