Little Disk Space
-----------------
The startup files can get rather large, so you may want to cut their
sizes a bit if you are running out of space.
`gnus-save-newsrc-file'
If this is `nil', Gnus will never save `.newsrc'--it will only
save `.newsrc.eld'. This means that you will not be able to use
any other newsreaders than Gnus. This variable is `t' by default.
`gnus-save-killed-list'
If this is `nil', Gnus will not save the list of dead groups. You
should also set `gnus-check-new-newsgroups' to `ask-server' and
`gnus-check-bogus-newsgroups' to `nil' if you set this variable to
`nil'. This variable is `t' by default.
