我不明白如何启动 slrn，特别是使用 jnewsrc 与 newsrc 文件：
nicholas@mordor:~$
nicholas@mordor:~$ slrn
slrn 1.0.3
Loading /usr/share/slrn/slang/slrn.sl
Reading startup file /etc/news/slrn.rc.
Using newsrc file /home/nicholas/.jnewsrc for server mordor.saundersconsulting.tech.slrn fatal error:
Unable to open /home/nicholas/.jnewsrc.
If you want to create /home/nicholas/.jnewsrc, add command line options:
-f /home/nicholas/.jnewsrc --create
nicholas@mordor:~$
nicholas@mordor:~$
nicholas@mordor:~$ slrn -f /home/nicholas/.jnewsrc --create
slrn 1.0.3
Loading /usr/share/slrn/slang/slrn.sl

目前使用 Pan 作为 NNTP，以 news.eternal-september.org 作为服务器。
